1.2 - DBE 4110 OVERVIEW
The DBE 4110 is a compact MPEG-2-standard encoding (or compression) device offering both MP@ML and 4:2:2P@ML standard. The use of the 4:2:2 Profile allows compression rates of up to 50Mbit/s without prior sub-sampling and ensures a high quality compression. Performance and cost-effectiveness are achieved through the THOMSON second generation chipset which offers five-level hierarchical motion estimation, far-ranging motion vector calculations and two-pass rate control for improved bit-rate allocation. The DBE 4110 single-service encoder performs encoding from a composite source or SDI with or without embedded audio. A maximum of 6 separate audio inputs are available. The DBE 4110 ensures interoperability with DVB-standard equipment. A fully DVB-compliant transport stream composed of video, audios, data as well as SI/PSI information is delivered directly in DVB-ASI format. Furthermore the DBE 4110 is fully compliant with the scrambling features defined by EBU (namely mode 1), for exchanging scrambled MPEG-2 streams. The DBE 4110 can be controlled through its front panel to facilitate basic operation. The DBE 4110 is provided with two Control&Command software programs, running on Windows NTTM based PC station using an Ethernet 10 baseT interface: • Fast_DSNG software for easy and intuitive operation, specially designed for DSNG operators, • Stand-Alone Control&Command software for advanced operation.
This document refers to release 7.0 of the DBE 4110.
Figure 1.2 gives an overview of the DBE 4110.

1.4.1 - Description of basic functions 1.4.1.1 - Video audio interface (SDI) The SMPTE 259M standard SDI input uses a female 75Ω BNC connector. It accepts a 270Mbit/s “component” 625 or 525 line serial stream. It operates with a 0200m length cable (type RG11A/V Filotex or 8281 Belden).
1.4.1.2 - De-embedded audio inputs Audio de-embedding is SMPTE 272MA-compliant. Audio de-embedding is possible when: • the video encoder uses the SDI input, • the video encoder is not used and there is a signal at the SDI input, and is not possible when the video encoder uses the composite video input. The 270Mbit/s signal can contain up to 8 stereo audios. The DBE 4110 can deembed 2 stereo audios which are either: • stereos 1 and 2 (DID = 2FF), or • stereos 3 and 4 (DID = 1FD), or • stereos 5 and 6 (DID = 1FB), or • stereos 7 and 8 (DID = 2F9). Characteristics: • synchronous 48kHz 20 bits audio, • de-embedding of 2 stereo audio channels, • C, U and V bits are ignored, • no pre-emphasis or de-emphasis.

The audio encoding module performs automatic audio/video compensation delay. The audio encoding module has audio pattern generation capability (2.1kHz 0dBFS signal). Input selection between analogue audio, de-embedded audio and AES/EBU audio (N41HATADAK option) is separate for the 2 MPEG-1 audio encoders. Selection is supervision-controlled. Mono, stereo or dual-channel can be selected either manually, or automatically from VPS information when present in the video source. All command running is seamless apart from audio/video compensation delay modification, analogue input level adjustment and changing between one and two PIDs. Each MPEG-1 dual channel encoder can be configured in such a way that it is conveyed as a single PID or as two distinct PIDs. In this case the audio encoder generates two single channel elementary streams, both having the same

configuration except for the PID and the language code (both components will have the same bitrate, etc.). When there is no video component, the MPEG-1 encoder is in “radio mode” and the delay (from SDI encoder input to PTS value, +/- 5ms) becomes equal to 150ms (50Hz and 60Hz).
1.4.1.8 - SI/PSI management The DBE 4110 has three operating modes for signalling generation: • no signalling generated, • generation of ISO tables (PAT, CAT, PMT, TSDT), • generation of DVB tables (ISO tables + SDT, TDT, TOT, BAT, NIT). The operating mode is selected by the operator. The DBE 4110 regularly broadcasts signalling information according to repetition rates that can be set up from the Control & Command station (remote control). Tables required for DVB DSNG operation are automatically generated according to transmitted signal configuration.
1.4.1.9 - Low delay mode Two trade offs between delay and video compression quality are now available: “Low delay” mode 4:2:0MP@ML MPEG-2 video
• Delay from SDI encoder input to PTS value (+/- 5ms): 320ms (50Hz), 267ms (60Hz), guaranteed delay from 4 to 15Mbit/s. • I and P pictures, no B picture.
4:2:2P@ML MPEG-2 video
• Delay from SDI encoder input to PTS value (+/- 5ms): 280ms (50Hz), 233ms (60Hz), guaranteed delay from 6 to 50Mbit/s. • I and P pictures, no B picture.

• Delay from SDI encoder input to PTS value (+/- 5ms): 100ms (50Hz), 100ms (60Hz), guaranteed delay from 6 to 50Mbit/s. • I pictures, no P and B pictures.
SIF mode is not available in ultra low delay mode. Use of MSU 4422 decoder adds approximately 70 ms to each delay. Switching between normal and low delay or ultra low delay is not seamless (picture is disturbed for 2 or 3 seconds). Bitrates below 4Mbit/s in low delay / 4:2:0 mode, and bitrates below 6Mbit/s in low delay / 4:2:2 mode and ultra low delay mode are reserved for almost still pictures, depending on encoding resolution and picture complexity.

1.4.1.11 - Stream Editing In order to obtain an editable MPEG stream between two time code values, the DBE 4110 encoder can insert an I picture and create a closed GOP when the incoming DVITC reaches a predefined value. The DBE 4110 automatically chooses the DVITC if it is on lines 19 and 332 (50Hz) or lines 11 and 274 (60Hz). If the DVITC is on other lines, the user must specify the lines using the DBS 2930 Control&Command software. The predefined value is sent to the DBE 4110 via MTEP / TCP/IP protocol (available on request). This value must be sent in advance with reference to the current time code value. The DBE 4110 can store up to 32 preset values. About this limit the new values are ignored. Notes: - Stream Editing does not operate with the VITC. - Stream Editing does not operate in 60Hz drop frame mode.

The COMPIN board features a VTR mode which is recommended for using bad quality, jittered signals. In VTR mode, the sampling is made on 8 bits instead of 10 and the bandwidth is around 3MHz. The COMPIN board features a built-in synchroniser. This synchroniser can be used in order to synchronise video input to an external composite video reference. This synchroniser can also be used with or without an external reference in order to help the encoder to deal with bad quality signals. The COMPIN board does not add any delay, except when the built-in synchroniser is activated and in that case it adds approximatively 30ms in 50Hz and 25ms in 60Hz. The synchroniser drops or repeats a frame when the accumulative delay between the input and the reference is excessive. Hence the lipsync evolves like a sawtooth between - 10ms and + 30ms (in 50Hz, without reference signal). In normal mode and in NTSC standard, the COMPIN board can be programmed to take into account or not a 7.5 IRE setup.
1.4.2 - Description of optional functions 1.4.2.1 - ASI TS input (option) Sales reference: N41STS1NAK ASI standard TS input on a female 75Ω BNC connector. The 270Mbit/s signal can carry 188/204 length TS packets. The max. TS data rate is 54Mbit/s. The TS Input interface accepts both “data burst” and “data packet” modes. Incoming data must be spread over time, so that no more than one TS packet is received over a period of 26µs. The external TS ASI input can be used for encoder cascading: up to three encoders can be cascaded by connecting the ASI output of one encoder to the ASI input of another one. This results in an MPTS with consistent PSI/SI tables, each video source having its own PCR unless the locking on incoming PCR is used (see the section below). To perform encoder cascading from the front panel, only one parameter must be set. When encoders are cascaded, incoming PID/service-id can be remapped to avoid conflicts.

Notes: - DBE 4110 TS OUT connected to DBE 4110 TS IN operates with a cable up to 200m in length, BELDEN 8281 type. - A programme going from ASI IN to ASI OUT will undergo a PCR jitter increase of +/75ns max. The maximum PCR jitter allowed by DVB standard is +/- 500ns. A programme encoded by a DBE 41XX will present an original PCR jitter of +/- 37.5 ns max.
∗
Locking on incoming PCR
This function requires the ASI TS input option. It is possible to create a single programme with components generated by more than one encoder. The principal application is the generation of a programme containing one video component and many audio components, like a "mosaic" programme or a mutilingual programme. All encoders must receive the same video source (even an encoder which is used only for audio encoding), and all encoders must use the same PCR. All encoders must be set to provide the same end to end delay. The use of the same PCR by all encoders is made possible by the new ability of the encoder to lock its internal PCR generator on the PCR coming from a component present in the ASI TS input stream. We recommend that you limit the cascade to three or less devices.

1.4.2.2 - DVB Common Scr. (option) Sales reference: N41SDVCFAK This option includes the capability to scramble the outgoing transport stream according to the DVB common scrambling standard. The DBE 4110 is fully compliant with the scrambling features defined by EBU (BISS modes 1 and E), for exchanging scrambled MPEG-2 streams. The control word is fixed. The fixed control word can be set using the front panel. No ECMs are broadcast in this case, and there is no need for EMM generation. The control word must be entered in the decoder to enable descrambling. Attention : 1. The incoming stream from the ASI input cannot be scrambled from the front panel and the Fast_DSNG software. To scramble the incoming stream, the encoder must be controlled by the DBS 2930 software with the N2930140 option (fixed control word) and the DBS 2908/11/12 MPEG Channel Controller. 2. The BISS mode E is only controlled by the front panel.

PROCEDURE
The following five steps are necessary before your encoder is ready for use: 1) Install the encoder. Installation involves the following steps: • manually set switches. • observe certain principles. • install the encoder in a rack. 2) Connect the encoder to other devices. 3) Switch on the device. 4) Adjust the cable corrector if the link exceeds 10m. 5) Install the control and command software. These various operations are described in the following sections.

2.1 - ENCODER INSTALLATION
The DBE 4110 encoder is designed for use in a horizontal position. The On/Off switch and the power cord should be within reach so that the device can be switched off easily.
2.1.1 - Manual switch setting " SSEB board - Set input impedance (audio)
The four switches LEFT 1, RIGHT 1, LEFT 2 and RIGHT 2 (mark 1) set incoming audio impedance. Each one comprises 2 switches which must be moved as a pair. Switch Up: high impedance
Switch Down: 600Ω impedance
The default setting is 600Ω. UP

• Enabling/Disabling the alarm relay In the event of a prompt alarm from the main processing board, a contact dry loop is activated on the MSDL board. The S2 switch (RSMAINT board) disables the alarm relay. The red LED (UNIT FAIL) comes on on the front panel of the device to signal the presence of a prompt alarm (regardless of S2 setting). Note: Do not forget to set the S2 switch from "Test/Alarm" back to "Normal" once the fault has been corrected.

• Choice of alarm relay mode In a system configuration with several DBE 41xx devices, the user can choose to interconnect the dry contacts of the alarm relays in series or parallel. The setting of the two microswitches on the MSDL board determines either open or closed contact mode: - choosing “open contact” for the alarm relay, associated with an unacknowledged fault means that all dry loop contacts must be set in series, - choosing “closed contact” for the alarm relay, associated with an unacknowledged fault means that all dry loop contacts must be set in parallel.

2.1.2 - Desktop installation The DBE 4110 encoder is fitted with four small plastic feet to ensure a minimum space of 1cm is guaranteed between the power supply of the encoder and the desktop for safety reasons.
2.1.3 - Rack installation Principles " " " " " " "
Prevent outgoing hot air being reinjected into other devices. Ensure an equal and acceptable air flow to the air-capture points of all devices. Avoid the effects due to natural convection between devices. Avoid short-cuts between hot and cold air and vice versa. Avoid transversal effects with connected racks. Avoid thermal pockets (obstruction of hot air). Check the air flow rate that will be used.
If the encoder is installed in a rack, the plastic feet can be removed. The device should be mounted on L-profiles in the rack. These should be low profile to ensure adequate air flow (see Figure 2.3). Note: The DBE 4110 encoder does not feature air filters. If used in a dusty environment, a filtered rack should be used.

3.1 - OPERATING PRINCIPLE
In stand-alone configuration, supervision is carried out from the front panel (described in this chapter) and from a PC terminal connected to the DBE 4110 by an Ethernet link and equipped with "Stand-alone" software supplied with the equipment (described in the following chapter) or Fast DSNG software (described in the chapter immediately afterwards). Front panel operation is designed to take into consideration the operating conditions of DSNG operators (Service Providers using the device for straightforward event coverage or the more complex occasional links). The following sections describe the control / command menu tree of the DSNG DBE 4110 encoder. Caution: When a parameter is changed by the supervision applications, the front panel display is not updated, it is necessary to validate the parameters.

4.5.3.1.2 - “Output” item
Figure 4.33: Parameters related to output Purpose: set the output signal. In the Output clock area Internally synthesised
The MPEG output signal rate is given by an adjustable internal frequency synthesiser. It is possible, using the Set command two lines below, to optimise the rate by minimising the number of null packets sent by the encoder. The calculation takes into account the values of the component rates generated by the device as well as the rates allocated to signalling and ECM. Notes: 1. If the TS output is exceeded, the component rate must not be increased. If this is the case, firstly reduce the component rate. It is necessary to increase first the TS output and then the component rate. 2. If the Set command does not take into account the Output clock changes when you modify the Max bitrate value. For example:

Optimal frequency
Minimum clock frequency of the TS for transmitting the defined service. This frequency can be calculated with the Set button. It can be useful to help recording the TS output on a server.
In the Maximum Bitrates area Signalisation
This value sets the alarm generation threshold and reserves the output rate required to send the signalling. When the equipment output rate is low, it is necessary to make adjustments to optimise the reserved rate. The maximum value is 3Mbit/s.
ECM
Used for alarm generation.
In the TS packet size area, the operator can choose the size of packets multiplexed in the outgoing TS. 188 bytes
This button corresponds to the standardised TS packet size, conforming to the MPEG2 ISO 13818-1: “Generic Coding of Moving Pictures and Associated Audio: Systems” standard.
188+16 bytes
The device adds 16 stuffing bytes after each 188 byte packet. This mode may be used when the device is connected to a satellite or cable modulator. The modulator then replaces these bytes by Reed-Solomon error correcting code. Note: When the ISMB board is used, TS packets must be in 188 + 16 form.

For the Country field, a list of countries is given by default. But it is possible to type three characters for the country code which is not proposed in the list. The lists of default language and country codes can be customised to include additional languages or countries or restrict default lists to the most common choices. These lists can be customised by changing the content of the codes.ini text file in the DBS 2930 setup directory. When language or country codes are defined in this file, the DBS 2930 uses these instead of the default lists regardless of the version (French or English) of the DBS 2930. The order in which codes are declared sets the order in which they appear in the choice lists. The file format observes Windows .ini file syntax.
Example of a .ini file [country_code] FRA=France [ISO_639_language_code] est=Estonien fre=Français
The [country_code] section contains the country codes. The name of each key is the ISO 8859-1 three-character code for the country. Its value is the text to be displayed in the list of choices. The [ISO_639_language_code] section contains the language codes. The name of each key is the ISO 639 three-character code for the language.

Notes: 1. When the Pattern source is selected, the internal PLL is no longer locked onto the video input, but to a fixed internal frequency. In these conditions, the SDI audio source transmitted with the video signal could give rise to alarms due to synchronisation problems, thereby creating disturbance in the sound signal. 2. There is no test to check whether the same PID is used as the output PID of two transiting components. PID instructions are considered to be instruction opportunities and only apply when the components do indeed feature on input. If however, the two components were to exist at the same time, one of them would be stopped and an alarm raised.
Profile
Choice between MP@ML and 422P@ML.
The Multiplex parameters area has the following fields: PID
Identification of the TS packets transporting the video component.
PCR
Choice between • No PCR: the component does not carry the PCR, • Service PCR: the component is referenced to carry the service PCR. In this case, the PID of this component fills the PCR PID field in the Service dialogue box (Figure 4.61 page 240), • Contains a PCR: the component carries a PCR without being referenced to carry the Service PCR. In this case, each component of the service can carry the PCR. These facilities mean that in remultiplexing operations, a TV service containing one video and several audios may be split into one TV service and several radio services each containing a single audio only.
Off air
This field is used to suspend transmission of the component without erasing it from the configuration.

The Compression area has the following fields: Rate
value between 0.5 and 15 Mb/s if MP@ML. value between 0.5 and 50 Mb/s if 4:2:2 P@ML. The operator can now set a video bitrate lower than the minimum bitrate indicated in the DBE 41xx encoder technical specifications. However, in any case an input of under 0.5 Mbit/s is rejected. When exiting the video parameter editing screen, a warning message requests the operator to confirm settings. The message specifies the minimum bitrate recommended by NEXTREAM for information purposes (i.e. 2 Mbit/s).
Figure 4.67: Warning message Mode
The mode optimises video compression. In Film mode, encoding and motion prediction are forced to frame mode because there is no motion between the 2 interleaved fields making up the frame. In Video mode, encoding and motion prediction are forced to field mode. In Auto mode, the encoder itself sets the best mode (film or video) having analysed the two interleaved fields. Only auto mode is capable of correct processing of a 3:2 pull down film mode (60Hz).

reception of the WSS signal, the format is specified by the field Default value 4:3 or 16:9. Note: With an SDI source transporting WSS in digital form (DID/SDID), you must declare the digital WSS in one of the VBI components (see section 4.5.4.1.3 - Editing parameters of the VBI component page 264). In any other case, it is all done automatically.
• Automatic AFD: format assignment depends on the AFD (Automatic Format Description) information contained in the incident 4:2:2 video signal. In case of non-reception of the AFD signal, the format is specified by the field Default value 4:3 or 16:9. Note: The AFD, also known as ARD, was defined by the BBC. It is the modified "video index" (line 11 and 324 in 50 Hz and 14 and 277 in 60 Hz) which supplies, among other things, information on image format (4:3, 16:9). The AFD can only be received in a video from the SDI input. The Aspect ratio default value is used until the AFD data has been received. Once the AFD has been detected, the image format is determined by the AFD data. Unlike WSS, when the AFD data disappears, the image format keeps the format contained in the AFD (it does not revert to the default format).

Note concerning the audio source names from the SDI input. An SDI signal can contain up to 16 mono audio channels. Two mono audios constitute an AES/EBU channel. AES/EBU channels are grouped in pairs and each pair forms a group. The reference of the AES/EBU channel is made up of the group number (1 to 4) and the number of the AES/EBU channel in the pair (1 or 2). Mono

Comments: 1. SSEB board: The SSEB board includes 2 stereo audio compressors, thus enabling two stereo audios in the output signal (stereo audios 1 and 2). The possible sources for the each stereo audio are as follows: • the SSEB board SDI input; • the SSEB board analogue input. When the SDI input is selected, a group number must be supplied. This number identifies the group to which the stereo audio belongs. When the source of the two stereo audios 1 and 2 is SDI, SSEB board internal wiring requires both stereo audios to be taken from the same group (one de-embedder for each pair of stereo audios).

2. ATADI board (option N41HATADAK): When this board is present, the list of possible sources for the audio 1 and audio 2 components contains two additional options: • the balanced digital input; • the unbalanced digital input. When the audio 1 and 2 source is a digital input, ATADI board internal wiring requires both inputs to be of the same type (Balanced or Unbalanced). 3. AMuSE board (option N41HAMUBAK): The AMuSE board is now dual-standard, i.e. MPEG-1 Layer II and Dolby AC-3. It is capable of packetising up to four Dolby AC-3 sounds from external audio encoders, or up to four sounds in MPEG-1 Layer II standard It is not possible to combine MPEG-1 Layer II encoding and Dolby AC-3 packetising with the same AMuSE board. The four audio channels on the AMuSE board are configured in either MPEG-1 Layer II or Dolby AC-3. In both cases, for each audio, the source options are as follows: the AMuSE board SDI input; the AES balanced digital input; the AES unbalanced digital input. When SDI input is selected, a group number must be supplied. This number identifies the group to which the audio component belongs. Some restrictions apply: 1. When the audio compressor 1 and 2 sources come from the SDI signal, internal wiring of the AMuSE board requires selection of the same group for the two sources. This rule also applies to compressor 3 and 4 sources. The SDI source (with AC-3 audio) must be synchronous with the one sent to the video encoder (SSEB board). 2. When the audio compressor sources are AES digital inputs, internal wiring of the AMuSE board requires all AES inputs to be of the same type (balanced or unbalanced). When either of these sources is used, the external Dolby encoder must be genlocked through the synchronisation output from the REF OUT connector on the AMuSE board. 4. PATTERN signal: The audio test signal consists in the transmission of a 2100 Hz frequency signal at 0 dBFS (full scale level). Be careful when using the audio test signal, as it produces a very loud sound. Note: In pre-compressed AC-3 mode, the AMuSE board does not generate an internal audio test signal.

The Multiplex area has the following fields: PID
Identification of the TS packets transporting the audio component.
PCR
Choice between • No PCR: the component does not carry the PCR, • Service PCR: the component is referenced to carry the service PCR. In this case, the PID of this component fills the PCR PID field in the Service dialogue box (Figure 4.61 page 240), • Contains a PCR: the component carries a PCR without being referenced to carry the Service PCR. In this case, each component of the service can carry the PCR. These facilities mean that in remultiplexing operations, a radio service containing several audios may be split into several radio services each containing a single audio only.

To change an audio mono-left or mono-right component to an audio stereo, joint-stereo or dual channel component, the other mono component must be deinstalled.
Rate
Choice between 64kb/s, 96kb/s, 128kb/s, 192kb/s, 256kb/s and 384kb/s according to the mode (MPEG standard does not allow any Mode/Rate combination).
VPS automatic mode
In MPEG Layer II compression mode, VPS information contained in the incident 4:2:2 video signal can be used to control automatic selection of the audio mode and the bitrate. When automatic VPS mode is validated, the input values in the Compression mode fields are default values that are only applied in the absence of VPS information. Note: With an SDI source transporting VPS in digital form (DID/SDID), you must declare the digital VPS in one of the VBI components (see section 4.5.4.1.3 - Editing parameters of the VBI component page 264). In any other case, it is all done automatically.
Alignment level and Headroom For analogue audio source only: The maximum input level is the analogue level in dBU with input saturation. After conversion, a digital level of 0 dBFS is produced. Two parameters are used to set the maximum input level: alignment level and headroom. Alignment is the level in dBU which corresponds to 0VU. It can be set between 0 and 4 dBU in 1 dBU steps. Headroom is the difference in dB between alignment level and input saturation. It can be set between 8 and 20 dB in 1 dB steps. Physically, the analogue audio input saturation level corresponds to alignment level + headroom in dBU.

This parameter is used to adjust the phase of the audio component with respect to the video component. The additional delay is used to recover a correct lipsync when a non-standard decoder is used. The accuracy of the value in ms is not guaranteed. Do not use the additional delay to compensate bad audio/video synchronisation of the encoder service signal. Please reboot the DBE 4110 after changing the additional delay. The additional delay should remain set to 0, which corresponds to a correct lipsync (tested with an MSU 4422 decoder). However, in certain conditions the TS bitrate used by THOMSON DBE 4110 MPEG-2/DVB Encoder - User manual

This change is only possible when an MPEG 1 Layer II coded audio component is attached to a service not containing any video component (radio service for instance). The Additional Delay parameter can then be set between –50ms and +350ms instead of 50ms/+50ms. The DBS 2930 performs the following checks: - when editing the parameters of an audio component, the value of the Additional Delay parameter is checked; - when adding a component to a service, addition of a video component is rejected if the service contains an audio component from an AMuSE board with an Additional Delay value of above 50ms.

The Component selection area is used for setting the injection parameters TS input and Input PID. Note: The incident PID is replaced by the one supplied by the Operating Station (see Figure 4.77 page 271).
The Incoming signalling area is used for programming the behaviour of the encoder with regard to incoming signalling. • If Dropped is selected, this means that the streamtype information and the descriptors contained in the PMT and the SDT input tables of the incoming TS stream are not kept. The Stream_type value of the first tab ("General") is taken into account and the Edit additional PMT info... and Edit additional SDT info... commands are used for adding new descriptors. • If Added to the local signalling is selected, this means that the stream-type information and the descriptors contained in the PMT and the SDT input tables are kept and added to the descriptors edited locally. The Stream_type value of the first tab ("General") is not used. Note: If a transiting service component is linked to a generated service via the "local" option for descriptor insertion, the list of descriptors mentioned will be associated with the component in both PMTs generated by the multiplexer (the descriptors associated with the component in the PMT of the original service are forgotten). In other words, the multiplexer only generates one context per component, and the transiting component is assigned the modifications made when it is used as a linked component.

4.5.4.2 - Advanced Functions 4.5.4.2.1 - Shared components A shared component is a component which is linked to two or more services in the SI/PSI tables. Actually data of a shared component are not duplicated. The elementary stream is just indicated by the signalling of different services. A typical application of shared components is a live information service. For instance this service could be a news service that displays stock exchange quotes on the TV set in real time. To be accessible from every service these data must be broadcast into each TS of the network and referenced by each service. There are three methods of implementation: Signalling

Figure 4.92: Principle of Shared Components In the first solution (case a), the elementary stream is duplicated for each service in the TS and is referenced as a private data component. The cost of this solution in terms of bandwidth is very high. The second way (case b) is to broadcast the elementary stream (ES) once in the TS. A private descriptor is used to reference the component. The decoder is able to interpret that descriptor and tune to the component. This solution is acceptable but not compatible with any remultiplexing operation since the component is not described in the SI/PSI signalling.

The last solution (case c) is to use the share component feature. The data are broadcast once and the component is described in SI/PSI signalling. Any type of component can be shared.
, Procedure 1. Select a service. 2. Select the Add components... command. 3. Consult the list of components. 4. Check the Show shared components box to display all the proposed resources (including those already used in another service). 5. Select the components to share in the list. 6. Click on OK. Shared components are displayed like the other components in the main window. This means they can appear several times in the tree view. Notes: 1. When parameters of a shared component are changed, all the items of the list referring to the shared component are updated. This means that each parameter of a shared component is identical regardless of the service except for the PCR. This parameter can have different values according to the generated service that uses it. When a shared component is removed from a service, it is not removed from other services. Actually only the reference to this service is deleted. But when a shared component is only referenced by one service, it automatically becomes a non shared component. The remove command works exactly as it does for a non shared component. 2. A shared component can only be scrambled locally if all the transmitted instances of this component belong to the same access group. Thus, when a component belongs to two services and scrambling is only required for one of the services, then the component is transmitted in clear.
4.5.4.2.2 - Ghost components Ghost components are components broadcast by an encoder that are not referenced in SI or PSI tables. To recover a ghost component the receiver must know its PID. Since the PID is not present in SI/PSI signalling, the receiver and the transmitter must have a non standard mechanism to exchange the PID. This could be a private

data descriptor or a private table. Ghost components are used by some networks for testing purposes or to generate non DVB/ISO streams. Notes: 1. Ghost components cannot automatically be transmitted at the remultiplexing stage even if the multiplexer is set to pass all services. They must be explicitly indicated to get through the multiplexer. 2. Ghost components cannot carry the PCR. 3. If a component is a ghost component (non indicated in the outgoing stream), It does not be associated to a service. If a component is declared "ghost component" issued of a SRV1 service on the tributary, and the broadcast of the service SRV1 is authorised without stopping the component, the component is neither a ghost component because it describes in the PMT of the service SRV1.
To avoid confusion for users who do not need this feature, the Ghost component item is hidden by default. To show this item and gain access to the ghost component facilities, select the Manage ghost components command in the pop-up menu of the Generated Services item.

All types of filtering are possible: • First level filtering: first level filtering provides global action on the TS input. The Unused command stops the TS input whilst the Used command lets the TS input stream through, applying the second, third and fourth level filtering conditions defined below. • Second level filtering: global filtering conditions may be defined (Stop all or Pass all) on each of the following three entities: services, EMM data, access control data. For both the Services and EMM data entities, additional filters can be used to authorise or drop individual services and EMM flows: Authorise a service to be transmitted or Drop a service and Authorise an EMM service or Drop an EMM service commands. Other facilities are also offered, e.g. • checking incident TS stream identity (not implemented), • selecting incident table processing mode, • authorising automatic reallocation of component PIDs in the event of conflict, • monitoring the TS input bitrate. Monitoring allows the TS input to be stopped if bitrate is exceeded with notification to the operator. • Third level filtering: the identification parameters for authorised services (service_id, service_type, service_name) and authorised EMM flows (EMM_PID) can be redefined. In addition, service components are filtered at this level; filtering may be global (Stop all or Pass all), or specific (Add a component or Drop a component). Other facilities are also proposed, e.g. • suspending or starting up transmission of a transit service, • attaching locally generated components to a transit service, • monitoring bitrates for incoming services. Monitoring allows incident services to be stopped if bitrate is exceeded with notification to the operator. • Fourth level filtering: all functions affecting components are grouped at this level, i.e.: • redefining a component PID. • suspending or starting up transmission of a transit component, • monitoring bitrates for incoming components. Monitoring allows incident components to be stopped if bitrate is exceeded with notification to the operator.

The encoder load can be reduced by requesting that only part of the incoming signalling is managed. There are five modes available: No signalling: all signalling arriving on the input is ignored. When this mode is enabled, all filtering instructions are ignored as there is no analysis of signalling. Consequently, the filters placed on this input are not implemented. Data received on this input can only be used to define TS components. Default: the mode selected is the same as that set for output (see editing of encoder advanced parameters). ISO signalling: Only ISO tables are analysed. DVB tables are ignored (SDT and EIT). If the multiplexer is configured to generate a DVB output signal, the current SDT is generated by default by the encoder by automatic creation of service and service provider names. DVB restricted: ISO and DVB tables are analysed except for EIT p/f and EIT s tables which are still filtered. The current SDT table is produced from the data elements available in the current incoming SDT. DVB signalling: ISO and DVB tables are analysed. The SDT and EIT tables for each service are retransmitted if the filtering instructions authorise transmission of the service.

If the signal is scrambled, only the ECMs and their references in the signalling are removed.
In the Case of PID conflict area PID reallocation authorised
If a transit component PID comes into conflict with a locally generated service PID, the encoder reallocates another available PID value.
PID reallocation not authorised
If a transit component PID comes into conflict with a locally generated service PID, the encoder stops the component and raises an alarm to the operating terminal.
Notes: 1. Generated components have priority over transiting components. So, when generating a component whose PID enters into conflict with that of a transiting component, the latter is stopped (if reallocation is barred on the tributary) or its PID is reallocated. A transiting component linked to a locally generated service is not considered as a generated component. 2. It is advisable not to change the authorised/not authorised reallocation mode during normal operation and to always keep the same mode. In PID reallocation authorised mode, the way in which PIDs are reallocated is directly linked to the order in which they are detected in the incoming stream. It is therefore not surprising that reallocation can differ between a redundant device and its back up device. 3. The device accepts both services with a PCR carried by a specific PID and reallocation of the supported PID as required; however, one case of reallocation has not been solved. take the following example: S1 (Vid = 200, Aud = 201, PCR = 400), S2 (Vid = 300, Aud = 301, PCR = 400), S3 (Vid = 400, Aud = 401, PCR = 400). If no specific reallocation instruction is given, the output signal will be correct. But if video 400 to video 500 reallocation is required, the output signal will be as follows: S1 (Vid = 200, Aud = 201, PCR = 400), S2 (Vid = 300, Aud = 301, PCR = 400), S3 (Vid = 500, Aud = 401, PCR = 500). In fact the result depends on the arrival and processing order of the PMTs. The problem does not arise if the PCR is not carried by a component.

This window may be accessed by clicking on or choosing the Services and data flow command in the drop-down View menu in the menu bar. The window consists of two sub-windows. The first sub-window displays the input services and rates on TS input. The second sub-window displays the output services and bit rates supplied by the encoder. Component bitrates are measured every second in the device. The bitrates fed back to the operating station appear fixed whereas in reality they fluctuate.
Figure 4.123: "Services and data flow" window The tree view has three levels: • at level one, the encoder (in the "Input services..." subwindow) and the Transport Stream conveying the set of services (in the "Output services..." subwindow). It shows the maximum rate allowed depending on the output frequency of the encoder and the size of the TS packets (see section 4.5.3.1.2 “Output” item page 194) as well as the current rate. • at level two, the services of the selected device with data flow information. The representation of services gives the name of the service, service identifier and service data flow. • at level three, the components of a service with data flow information. The representation of components depends on their scrambling (the icon is greyed out if the component is scrambled). Information given for components includes component type (Video, Audio, etc.), PID (in decimal and hexadecimal) and component data flow. 47232437AK01 June 2003

4.8 - {EVENT LOG} APPLICATION
4.8.1 - Principles of the {Event Log} application The purpose of this paragraph is to list all the functions of the {Event Log} application.
4.8.1.1 - Event " Event types The event types displayed are as follows: • • • • • • • •
rising alarm; falling alarm; reboots; device connections; device disconnections; device configuration changes (activations); service switching (to replacing) by INBAND command; service switching (to regular) by INBAND command.
" Paired events Some events can be grouped into pairs. Paired events are: • rising and falling alarm; • service switching to replacing and regular by INBAND command; • setup and release of connections with devices.
" Parameters displayed Each event is displayed with the following parameters: • • • •
a record number; an event identifier (event_id); a sub-identifier (event_extension); the name of the device which caused the event;

• the text describing the event; • the date and local time of event occurrence; • the duration (this parameter is significant only for rising alarm events).
4.8.1.2 - View configuration functions These functions facilitate event viewing by displaying just some of the information according to operator-defined criteria.
" Sorting Sorting consists of changing the order in which events are displayed in the list. Two sort options are available: • sorting by record number; • sorting by date and time.
" Filtering Filtering consists of defining events to be displayed on the screen. Those displayed satisfy the following criteria: • they belong to event identifier lists; • they come from given devices; • they fall between two dates set by the Operator.
" Masking This function is used to mask the display of certain untimely events. These events are not deleted, they are simply no longer visible.
" Searching This function is used to move the cursor in the view of the current event to the event with which it is paired. If the search fails (the paired event is not present or not visible on account of the filter applied), an error message notifies the operator that the command has failed.
4.8.1.3 - Event exporting It is now possible to export the list of events to a text file. Any given event is represented over one line, each field of the event being delimited by a tabulation. 47232437AK01 June 2003

" Calculation of durations
The Tools/Calc durations... command in the menu bar is used to calculate the duration between a rising alarm and a falling alarm or the next device reboot. Given the time required for the calculation, this command is only available on backup files and the Operator has to confirm command execution. Once the calculation has been performed, the duration of each event is displayed in the Duration column in the main window. Durations are stored in the event log file. It is not necessary to recalculate duration each time a file is opened. Note: When the calculation proves impossible (if the falling alarm is not saved in the same file) or duration is insignificant, the Duration column remains blank.

4.10.3.3 - LTW_offset Set LTW_offset flag when service PCR (Yes:1 No:2) (x)? This parameter tells the encoder whether or not it should add the LTW offset value to the video when the video is carrying the PCR. Default value = 1.
4.10.3.4 - SPE (SuperEncoder) switch source mode SPE switch source mode (same as old board:1 same as new board:2) (x)? This parameter is used to choose the SuperEncoder board switch mode: • if you have an old version of the board (version AG), mode 1 must be selected • if you have a recent version of the board (versions AH, AJ or AK), mode 2 must be selected. However, if the video input signals are not synchronous then interference caused by the switch appears on the picture. In this case mode 1 can be used to reduce interference.
4.10.3.5 - VBI stream type VBI stream_type with MT lines (ISO:1 BARCO:2) (x)? This parameter is used to choose the stream type value used for Monochrome transparent VBI components. The (ISO) default value is the 0x06 standardised value. The other possible (BARCO) value is 0x92 which corresponds to a BARCO proprietary value used for Monochrome transparent lines. All Monochrome transparent lines generated by the encoder have either a 0x06 or 0x92 stream type value and no combination is possible. A descriptor must be added to the PMT. See {Technical Configuration} application section Editing parameters of the VBI component page 264.
4.10.3.6 - LDSChurch mode LDSChurch mode -ignored when SPE board is declared- (ON:1 OFF:2) (x) ? This mode only concerns operation in 60Hz mode. When the mode is set to ON, the active lines in fields 1 and 2 are moved up a line. The first active line is therefore line 21 for field 1 and line 284 for field 2 (the first line being line 1). This mode is used to transmit the sub-titles as a useful part of the video signal. THOMSON DBE 4110

On a DBE 4130 or 4150 Encoder featuring a SuperEncoder board, this parameter is not acknowledged and the lines are not moved up. The SuperEncoder board is detected when the device is turned on. Checking the "closed caption" box in the DBS 2930 Operating station, video component parameters VBI tab is unnecessary. If the box is checked, the sub-titles will be transmitted in the video stream twice (as user data and in line 21). Default value = 2
4.10.3.7 - ABSAT mode ABSat mode (ON:1 OFF:2) (x) ? This mode, designed for the DBE 4130 Encoder, is used to modify Video encoding so that it is compatible with Philips "G+2" series decoders. When ABsat mode has been selected: - the VBV delay value is calculated and sent for each picture, - the default quantisation matrix is systematically included for each I-picture. The DBE 4130 Encoder in ABSat mode remains DVB compliant. Notes: - operation in ABSat mode is not guaranteed with decoders other than Philips "G+2" series decoders. - ABsat mode has been designed for the DBE 4130 Encoder. Operation in ABsat mode is not guaranteed for other DBE 41XX Encoders. - ABsat mode only operates in 50Hz mode. - the Helper Channel application, which is a specific function of the DBE 4120 Encoder, does not operate in ABsat mode. Default value = 2
4.10.3.8 - Multichoice-D1 mode Multichoice-D1 mode (ON:1 OFF:2) (x) ? This mode implements an MPEG-2 syntax specifically for the video component. - Each PES contains a single GOP, - The PES is formatted as follows:

- the DataAlignmentIndicator bit is set to 1 (PES payload begins on a video "Elementary Stream" header), - the PES data length field uses 10 bytes instead of 11 for I and P-pictures (a 0xFF stuffing byte has been deleted). - There is no stuffing byte between pictures at "Elementary Stream" level (no 16-bit alignment), - There is no stuffing "Elementary Stream" (minimum payload at TS level). When the mode is set to OFF, each PES contains a picture, the DataAlignmentIndicator is set to 0, the PES data length field uses 11 bytes, there is a number of stuffing "Elementary Streams" (required to align the start of the PES with the start of the TS packet) and there is no longer 16-bit alignment. Default value = 2.
4.10.3.9 - Foxtel 6dB uplift Foxtel 6dB uplift (ON:1 OFF:2) (x) ? This mode adds +6dB of gain to audio samples encoded in MPEG-1 by the SSEB board. The audio is doubled before peak limiting and encoding. All SSEB board audio inputs are concerned: - SDI, - Analogue audio converted to digital. All audio components encoded by the SSEB board are affected. AES/EBU audio signals generated by the ATADI board are affected. The 2.1kHz test signal, 0dB generated by the SSEB board is not affected. Audio signals generated by the AMUSE board are not affected. The uncompressed audio mode (DBE 4120) is not affected. Note: you are advised not to use Foxtel mode and a 384Kbit/s bitrate at the same time, as in this case audio quality is not guaranteed. Default value = 2

4.10.3.10 - Closed Caption type Closed Caption type -only with DBE4130- (DVB/ATSC:1 DVB/DSS:2) (x) ? In 60Hz mode, the DBE 41XX can extract line 21 sub-title information (the first line being line 1) from the video input signal (if the information is modulated and not binary) and can insert it into the "Video Elementary stream" according to the ATSC A/53 standard. This is done when the "Closed caption" box is checked in the Technical Configuration application, video component advanced parameters, VBI tab. With a DBE 4130 Encoder, the sub-titles can be inserted into the "Video Elementary stream" according to two standards: DVB/ATSC: 1 = "DVB / ATSC A/53" standard, DVB/DSS: 2 = "DTV95MDB-04, DirectTV MPEG1 and MPEG2 video stream specifications for IRDs, version 2.1" standard. This parameter does not affect the MPEG-2 TS layer or the PSI and SI tables. This function is only implemented on DBE 4130 Encoders. On other DBE 41XX Encoders, the parameter value is set to 1. Default value = 1 (DVB/ATSC A/53)
4.10.3.11 - Extended-data insertion (line 284) Extended-data insertion (line 284) -only with DBE4130- (ON:1 OFF:2) (x) ? Line 21 of the second field (i.e. line 284) can contain information similar to sub-title information known as "extended data services". This parameter can have two values: 2 = OFF 1 = ON, the "extended data services" data is extracted from the video input signal (only in modulated form) and inserted into the "Video Elementary stream" syntax in the same way as the sub-titles. This function is only implemented on DBE 4130 Encoders operating in 60Hz mode. On other DBE 41XX Encoders, the parameter value is set to 2 (OFF).

5.1 - FAST-DSNG
A DSNG system is used to transmit pictures and sound between the site of an event and a professional television (producer, television channel, etc.). The signals are produced at the site of the event from a mobile system containing the equipment required to produce video and audio signals and transmit them to a site for broadcast via a satellite link. The size of the DSNG system can vary considerably, depending on the coverage desired for the event and the mobility required. A DSNG system can just as easily be a camera, encoder, satellite modulator/up-converter which can fit into one or two flight cases, as several O.B. vans containing cameras, mixing desks, encoders, cables, etc. Those involved in DSNG systems are: - satellite operators; - satellite antenna manufacturers; - satellite modem manufacturers; - manufacturers of power amplifiers and RF systems; - video encoder/decoder manufacturers; - audio encoder/decoder manufacturers; - supervision system manufacturers; - systems integrators. "

Setting up DSNG communications
Setting up a satellite link requires that a procedure defined by the satellite operator be followed: 1. The satellite operator notifies the DSNG operator of the: - position of the satellite; - transmission power; - uplink frequency; - bandwidth; - downlink frequency after frequency translation by the satellite. 2. The DSNG operator contacts the reception station by telephone and begins a connection procedure. 3. This operator directs the satellite antenna and transmits a low power, pure carrier on the uplink frequency. When communication occurs on frequency C-band, spectral inversion may be required. 47232437AK01 June 2003

Chapter 5 5.1 - Fast-DSNG
4. The reception station confirms reception of the signal. 5. From this moment onwards, the DSNG operator can no longer interrupt the signal transmitted to the satellite because signal absence may be interpreted by automatic frequency allocation systems as availability of the frequency and bandwidth. 6. The DSNG operator increases the power and sets the modulator to modulation mode. 7. If the operator has a decoder and his geographical position enables him to receive the transmitted signal, he checks that the transmission is being sent correctly. In the event of a problem, he may also check the signal at the modulator output by using the L-BAND output.

Purpose
This software is supplied as standard with DBE 4110 encoders. The main purpose of this software is to facilitate input of the parameters required for setting up a satellite link on the encoders and the modulator. Configuration using the graphic interface is very simple. The operator can display all the transmission parameters together with the composition of the transmitted signal on six screens. Configuration changes are optimised by reducing operator actions. The software operates on a PC (laptop) with standard performance, featuring: - Windows 95, 98 or NT operating system; - Ethernet 10BaseT interface; - 640x800 colour screen with 256 colours; - pointer device (mouse or other). The application is only available in English.

Chapter 5 5.5 - Operation
5.5.2 - Setup panel This panel is mainly used on initial application start-up. It allows the software to be configured to indicate: - whether Control/Command communication of the equipment is enabled or disabled; - the system configuration (1, 2 or 3); - the parameters required for setting up the Control/Command links of the encoders, i.e. their IP address. The parameters are saved to the hard disk and are read automatically each time the software is started up. They are saved in a file of the Windows initialisation file (.ini) type.
Figure 5.2: Setup panel
The choice of configuration and IP addresses of the encoders is only possible when communication with the devices is stopped. To do this, press the button in the bottom left hand of the window. Follow the instructions in the box on the right-hand side of the panel: • Enter the IP address of the first encoder, THOMSON DBE 4110 MPEG-2/DVB Encoder - User manual

• Select other devices, modulator or a second encoder: - Check Controls a modulator box (if a modulator is present), - Check Uses an external signal in TS input box, to enable the TS input (the option is present in the first encoder) to be connected to an external device not controlled by the {Fast_DSNG} application, - Check Use and Control a second encoder box, to allow the control of a second encoder. The TS input option must be present in the second encoder (check Use an external signal in TS input box), enter its IP address, - Enter the name of the service in the Station name put in window, 6 characters plus -1 (or -2).
Caution! The encoder(s) and the PC must have different IP addresses. If two devices have the same IP address, software behaviour may be unpredictable.
When the information has been entered, press Connect to DSNG system to start up Control/Command communication with devices. When communication is enabled, the software attempts to set up communication with the encoder(s) in order to gather the configuration information displayed to the user in the other panels.

5.5.3.1 - Transmission parameters Transmission parameters are found in two areas. The upper area is used during the procedure for setting up satellite communication. The lower area is used for configuring the modulator. In the upper part, four buttons control the modulator output: • In Off position (key F9), the modulator does not transmit a signal. The operator can then set the modulation parameters (frequency, bandwidth, etc.) in the lower area. The application does not send any configuration to encoder. • In Ready position (key F10), the modulator does not transmit, the parameters can no longer be edited. The software sends the configuration to the encoders. • In any Pure carrier position (key F11), the modulator transmits a pure carrier with the level displayed under the button. The parameters entered in the lower area can no longer be edited. • In Modulation position (key F12), the modulator transmits a modulated signal with the level set to High. In this mode, level and modulation parameters can no longer be edited. Note: If the system is disconnected, all the devices remain in the initial state. The parameters displayed in the lower area can only be modified in the Off position (key F9). Access is unauthorised in the other positions and the cursor indicates this by changing its form ( ). The Symbol rate and Bandwidth parameters are interlinked by a formula that involves the Convolution parameter. Each time the operator changes one of these three, the Bandwidth and/or Symbol rate parameters are recalculated immediately. Thus, if the operator enters the symbol rate, the application will immediately calculate the bandwidth for information purposes, or vice versa. The calculated value will be displayed in the process. Note: If a bad format is chosen, the bandwidth cannot be calculated and the field remains blank. An error message is displayed.

5.5.3.2 - Parameters linked to encoder control and signal content In Figure 5.3, the right-hand area of the dialogue box is dedicated to encoder control and the content of the transmitted signal. The button in the Components area title is used to quickly modify the service-id parameter.
Figure 5.4: Service Id Editor
It displays two lists of available components (one list per encoder). The content of the list depends on the software and hardware options installed on each encoder. Above each list, an alarm symbol appears in front of each encoder name. Its appearance depends on alarm status: • Green: no alarm, • Orange or red flashing: alarms have occurred. In the list, a check box in front of each item allows a component to be inserted into the signal transmitted to the satellite. By clicking these boxes, the components are inserted into, or removed from, the signal one by one. If the Video bitrate automatic adjustment in the Transmission panel is checked, each time a component is inserted into or removed from the signal, the application recalculates the bit rate of the video components automatically to ensure optimum use of the bandwidth. For systems with two encoders, the rate allocated to each video component is always identical. For advanced use, a button located under each list allows access to parameters of the component selected in the list. This screen can be used to modify the PID, profile or other advanced parameters. The presentation of the parameters in these screens is identical to that of the DBS 2930. To change video parameters, the procedure is: 1. Select the component, 47232437AK01 June 2003

This panel is used to configure each encoder with the configurations saved in the encoder memory, save configurations and delete backup configurations. Two types of memory are defined for DBE 4110 encoders: • the authorised read and write memories that can be programmed by the Operator using the Fast_DSNG software. • the authorised read-only memories that are programmed at the manufacturers. They contain the standard predefined configurations. The contents of these memories cannot be changed by the Operator. A list is displayed for each encoder in which each line represents a memory identified by a number or letter (1 to 8 for read and write memories; and A, B, and C for read-only memories). Each line also contains the name of the archived configuration and the memory status (Empty, Read only or Used). No name is shown in the second column when a memory is empty.

5.5.8 - Dynamic behaviour This section contains the software specification elements that are liable to change.
5.5.8.1 - No connection On starting up the application, the software attempts to set up a control/command link with the main encoder then with the second encoder. As long as all connections (one or two depending on the configuration) are not set up, the configuration parameters are not displayed. As long as communications are not set up, the encoder parameters in the Transmission, Alarms, Scrambling and Information panels are masked.
5.5.8.2 - Setting up a connection As soon as all the connections are set up, the software displays the current configuration. If the encoder does not know how manage the current configuration, it sends a message and proposes another standard configuration. • For a configuration with two encoders, the following tests are carried out: - If the Main encoder does not feature the N41STSIN option, communications are broken and a message is displayed; - If the Main encoder features the N41STSIN option, the TS input configuration is forced to allow all the services through.
• When an external signal is used on the TS input, all the services pass through. Once the tests have been carried out, the encoder configuration is displayed on the software screens. Subsequently, the alarms are regularly requested from the device and displayed in the Alarms panel.

Chapter 6 6.1 - Device connection problems
6.1 - DEVICE CONNECTION PROBLEMS
Connection problems are often difficult to solve as causes are numerous and varied. A malfunction may be caused by the network being incorrectly set-up on the PC, a wiring problem or damage to a non-responding device. The aim of this section is to provide a procedure that can be followed to solve these problems in a minimum of time. When the DBE 4110 is signalled as not responding, proceed as follows: 1. Check that the DBE 4110 is operational and that the front panel is working, by moving around the menus. 2. Check that the IP address assigned to the device on the PC in the {Equipment Installation} application matches the one assigned to the device displayed on the front panel in the Other/Tools/IP Address menu. 3. Check that the DBE 4110 responds to network prompts; use the Ping IP address command in an MS-DOS window. If the device responds, skip the next paragraph. 4. Check the value of the subnet mask in the network set-up panel on the PC; the subnet mask identifies the part identifying the subnet in the IP address; like an IP address it consists of 4 numbers separated by "."; if the device address is not in the subnet, the device will not be accessible. 5. Check the cables with the ohmmeter; Ethernet cables are quite fragile and connector crimping may be faulty.

5. Measure the fuse value with an ohmmeter. - If a fuse is faulty, contact the NEXTREAM Customer Service. A faulty fuse indicates that the product is damaged. You are therefore not advised to simply change the fuse. Please have the product inspected by a qualified member of NEXTREAM maintenance staff. - If the fuse is not faulty, another fuse in the power supply drawer may be faulty. To inspect this fuse, the unit requires dismounting and hence comes under a higher maintenance level. The procedure is not described in this manual.

6.3.1 - Fan life expectancy The DBE 4110 has built in fans with a life expectancy of roughly 7 years at 30°C (6 years at 40°C). When your DBE 4110 reaches this age, fans will need to be replaced; please, contact NEXTREAM After Sales Service.
6.3.2 - Front panel LCD blank If the DBE 4110 is on and the front panel LCD is backlighted but does not show any indication or shows only four rows of black blocks, check that the contrast is properly set.
6.3.3 - Default analogue video input In the case of a device fitted with a DPSN board, the choice analogue video input PAL/SECAM (50Hz) or NTSC (60 Hz) should be available. If not, check that the DPSN board has been declared present ("Other/Tools/Option/Hardware").
6.3.4 - Autotest problem When a device cannot exit the autotest, try to clear the memory. To do this, switch off and set the rotary switch (on the RSMAINT board, if present, if not, on the SSEB board) to position 5. Switch on, wait 1 minute, switch off, return the rotary switch to position 0, and switch on. However, all the configurations (the current one and those saved) will be lost.

Chapter 1 1.2 - DBE 4110 overview
1.2 - DBE 4110 OVERVIEW
The DBE 4110 is a compact MPEG-2-standard encoding (or compression) device offering both MP@ML and 4:2:2P@ML standard. The use of the 4:2:2 Profile allows compression rates of up to 50Mbit/s without prior sub-sampling and ensures a high quality compression. Performance and cost-effectiveness are achieved through the THOMSON second generation chipset which offers five-level hierarchical motion estimation, far-ranging motion vector calculations and two-pass rate control for improved bit-rate allocation. The DBE 4110 single-service encoder performs encoding from a composite source or SDI with or without embedded audio. A maximum of 6 separate audio inputs are available. The DBE 4110 ensures interoperability with DVB-standard equipment. A fully DVB-compliant transport stream composed of video, audios, data as well as SI/PSI information is delivered directly in DVB-ASI format. Furthermore the DBE 4110 is fully compliant with the scrambling features defined by EBU (namely mode 1), for exchanging scrambled MPEG-2 streams. The DBE 4110 can be controlled through its front panel to facilitate basic operation. The DBE 4110 is provided with two Control&Command software programs, running on Windows NTTM based PC station using an Ethernet 10 baseT interface: • Fast_DSNG software for easy and intuitive operation, specially designed for DSNG operators, • Stand-Alone Control&Command software for advanced operation.
This document refers to release 7.0 of the DBE 4110.
Figure 1.2 gives an overview of the DBE 4110.

1.4 - SPECIFICATIONS
1.4.1 - Description of basic functions 1.4.1.1 - Video audio interface (SDI) The SMPTE 259M standard SDI input uses a female 75Ω BNC connector. It accepts a 270Mbit/s “component” 625 or 525 line serial stream. It operates with a 0200m length cable (type RG11A/V Filotex or 8281 Belden).
1.4.1.2 - De-embedded audio inputs Audio de-embedding is SMPTE 272MA-compliant. Audio de-embedding is possible when: • the video encoder uses the SDI input, • the video encoder is not used and there is a signal at the SDI input, and is not possible when the video encoder uses the composite video input. The 270Mbit/s signal can contain up to 8 stereo audios. The DBE 4110 can deembed 2 stereo audios which are either: • stereos 1 and 2 (DID = 2FF), or • stereos 3 and 4 (DID = 1FD), or • stereos 5 and 6 (DID = 1FB), or • stereos 7 and 8 (DID = 2F9). Characteristics: • synchronous 48kHz 20 bits audio, • de-embedding of 2 stereo audio channels, • C, U and V bits are ignored, • no pre-emphasis or de-emphasis.

The audio encoding module performs automatic audio/video compensation delay. The audio encoding module has audio pattern generation capability (2.1kHz 0dBFS signal). Input selection between analogue audio, de-embedded audio and AES/EBU audio (N41HATADAK option) is separate for the 2 MPEG-1 audio encoders. Selection is supervision-controlled. Mono, stereo or dual-channel can be selected either manually, or automatically from VPS information when present in the video source. All command running is seamless apart from audio/video compensation delay modification, analogue input level adjustment and changing between one and two PIDs. Each MPEG-1 dual channel encoder can be configured in such a way that it is conveyed as a single PID or as two distinct PIDs. In this case the audio encoder generates two single channel elementary streams, both having the same

configuration except for the PID and the language code (both components will have the same bitrate, etc.). When there is no video component, the MPEG-1 encoder is in “radio mode” and the delay (from SDI encoder input to PTS value, +/- 5ms) becomes equal to 150ms (50Hz and 60Hz).
1.4.1.8 - SI/PSI management The DBE 4110 has three operating modes for signalling generation: • no signalling generated, • generation of ISO tables (PAT, CAT, PMT, TSDT), • generation of DVB tables (ISO tables + SDT, TDT, TOT, BAT, NIT). The operating mode is selected by the operator. The DBE 4110 regularly broadcasts signalling information according to repetition rates that can be set up from the Control & Command station (remote control). Tables required for DVB DSNG operation are automatically generated according to transmitted signal configuration.
1.4.1.9 - Low delay mode Two trade offs between delay and video compression quality are now available: “Low delay” mode 4:2:0MP@ML MPEG-2 video
• Delay from SDI encoder input to PTS value (+/- 5ms): 320ms (50Hz), 267ms (60Hz), guaranteed delay from 4 to 15Mbit/s. • I and P pictures, no B picture.
4:2:2P@ML MPEG-2 video
• Delay from SDI encoder input to PTS value (+/- 5ms): 280ms (50Hz), 233ms (60Hz), guaranteed delay from 6 to 50Mbit/s. • I and P pictures, no B picture.

“Ultra low delay” mode 4:2:0MP@ML MPEG-2 video
• Delay from SDI encoder input to PTS value (+/- 5ms): 140ms (50Hz), 134ms (60Hz), guaranteed delay from 6 to 15Mbit/s. • I pictures, no P and B pictures.
4:2:2P@ML MPEG-2 video
• Delay from SDI encoder input to PTS value (+/- 5ms): 100ms (50Hz), 100ms (60Hz), guaranteed delay from 6 to 50Mbit/s. • I pictures, no P and B pictures.
SIF mode is not available in ultra low delay mode. Use of MSU 4422 decoder adds approximately 70 ms to each delay. Switching between normal and low delay or ultra low delay is not seamless (picture is disturbed for 2 or 3 seconds). Bitrates below 4Mbit/s in low delay / 4:2:0 mode, and bitrates below 6Mbit/s in low delay / 4:2:2 mode and ultra low delay mode are reserved for almost still pictures, depending on encoding resolution and picture complexity.

1.4.1.11 - Stream Editing In order to obtain an editable MPEG stream between two time code values, the DBE 4110 encoder can insert an I picture and create a closed GOP when the incoming DVITC reaches a predefined value. The DBE 4110 automatically chooses the DVITC if it is on lines 19 and 332 (50Hz) or lines 11 and 274 (60Hz). If the DVITC is on other lines, the user must specify the lines using the DBS 2930 Control&Command software. The predefined value is sent to the DBE 4110 via MTEP / TCP/IP protocol (available on request). This value must be sent in advance with reference to the current time code value. The DBE 4110 can store up to 32 preset values. About this limit the new values are ignored. Notes: - Stream Editing does not operate with the VITC. - Stream Editing does not operate in 60Hz drop frame mode.

The COMPIN board features a VTR mode which is recommended for using bad quality, jittered signals. In VTR mode, the sampling is made on 8 bits instead of 10 and the bandwidth is around 3MHz. The COMPIN board features a built-in synchroniser. This synchroniser can be used in order to synchronise video input to an external composite video reference. This synchroniser can also be used with or without an external reference in order to help the encoder to deal with bad quality signals. The COMPIN board does not add any delay, except when the built-in synchroniser is activated and in that case it adds approximatively 30ms in 50Hz and 25ms in 60Hz. The synchroniser drops or repeats a frame when the accumulative delay between the input and the reference is excessive. Hence the lipsync evolves like a sawtooth between - 10ms and + 30ms (in 50Hz, without reference signal). In normal mode and in NTSC standard, the COMPIN board can be programmed to take into account or not a 7.5 IRE setup.
1.4.2 - Description of optional functions 1.4.2.1 - ASI TS input (option) Sales reference: N41STS1NAK ASI standard TS input on a female 75Ω BNC connector. The 270Mbit/s signal can carry 188/204 length TS packets. The max. TS data rate is 54Mbit/s. The TS Input interface accepts both “data burst” and “data packet” modes. Incoming data must be spread over time, so that no more than one TS packet is received over a period of 26µs. The external TS ASI input can be used for encoder cascading: up to three encoders can be cascaded by connecting the ASI output of one encoder to the ASI input of another one. This results in an MPTS with consistent PSI/SI tables, each video source having its own PCR unless the locking on incoming PCR is used (see the section below). To perform encoder cascading from the front panel, only one parameter must be set. When encoders are cascaded, incoming PID/service-id can be remapped to avoid conflicts.

Notes: - DBE 4110 TS OUT connected to DBE 4110 TS IN operates with a cable up to 200m in length, BELDEN 8281 type. - A programme going from ASI IN to ASI OUT will undergo a PCR jitter increase of +/75ns max. The maximum PCR jitter allowed by DVB standard is +/- 500ns. A programme encoded by a DBE 41XX will present an original PCR jitter of +/- 37.5 ns max.

Locking on incoming PCR
This function requires the ASI TS input option. It is possible to create a single programme with components generated by more than one encoder. The principal application is the generation of a programme containing one video component and many audio components, like a "mosaic" programme or a mutilingual programme. All encoders must receive the same video source (even an encoder which is used only for audio encoding), and all encoders must use the same PCR. All encoders must be set to provide the same end to end delay. The use of the same PCR by all encoders is made possible by the new ability of the encoder to lock its internal PCR generator on the PCR coming from a component present in the ASI TS input stream. We recommend that you limit the cascade to three or less devices.

The DBE 4110 is fully compliant with the scrambling features defined by EBU (BISS modes 1 and E), for exchanging scrambled MPEG-2 streams. The control word is fixed. The fixed control word can be set using the front panel. No ECMs are broadcast in this case, and there is no need for EMM generation. The control word must be entered in the decoder to enable descrambling. Attention : 1. The incoming stream from the ASI input cannot be scrambled from the front panel and the Fast_DSNG software. To scramble the incoming stream, the encoder must be controlled by the DBS 2930 software with the N2930140 option (fixed control word) and the DBS 2908/11/12 MPEG Channel Controller. 2. The BISS mode E is only controlled by the front panel.

• Enabling/Disabling the alarm relay In the event of a prompt alarm from the main processing board, a contact dry loop is activated on the MSDL board. The S2 switch (RSMAINT board) disables the alarm relay. The red LED (UNIT FAIL) comes on on the front panel of the device to signal the presence of a prompt alarm (regardless of S2 setting). Note: Do not forget to set the S2 switch from "Test/Alarm" back to "Normal" once the fault has been corrected.

• Choice of alarm relay mode In a system configuration with several DBE 41xx devices, the user can choose to interconnect the dry contacts of the alarm relays in series or parallel. The setting of the two microswitches on the MSDL board determines either open or closed contact mode: - choosing “open contact” for the alarm relay, associated with an unacknowledged fault means that all dry loop contacts must be set in series, - choosing “closed contact” for the alarm relay, associated with an unacknowledged fault means that all dry loop contacts must be set in parallel.

2.1.2 - Desktop installation The DBE 4110 encoder is fitted with four small plastic feet to ensure a minimum space of 1cm is guaranteed between the power supply of the encoder and the desktop for safety reasons.
2.1.3 - Rack installation Principles " " " " " " "
Prevent outgoing hot air being reinjected into other devices. Ensure an equal and acceptable air flow to the air-capture points of all devices. Avoid the effects due to natural convection between devices. Avoid short-cuts between hot and cold air and vice versa. Avoid transversal effects with connected racks. Avoid thermal pockets (obstruction of hot air). Check the air flow rate that will be used.
If the encoder is installed in a rack, the plastic feet can be removed. The device should be mounted on L-profiles in the rack. These should be low profile to ensure adequate air flow (see Figure 2.3). Note: The DBE 4110 encoder does not feature air filters. If used in a dusty environment, a filtered rack should be used.

Ensure that the device is properly grounded before power-up. On the rear panel, connect the power cable and turn the power switch to ON. When the device is switched on, check that the green "POWER" LED on the front panel is on. If not, refer to the "Troubleshooting" chapter. When switched on, the device runs an autotest after which the main screen is displayed (see Welcome and main screens page 108). Caution: • When the DBE 4110 encoder is first switched on, the non volatile RAM is initialised with a configuration not defining any service. It is necessary to create or recall a service. Refer to the "PC operation - Control & Command software" chapter. • When the device is switched on, the last active configuration is loaded.

3.1 - OPERATING PRINCIPLE
In stand-alone configuration, supervision is carried out from the front panel (described in this chapter) and from a PC terminal connected to the DBE 4110 by an Ethernet link and equipped with "Stand-alone" software supplied with the equipment (described in the following chapter) or Fast DSNG software (described in the chapter immediately afterwards). Front panel operation is designed to take into consideration the operating conditions of DSNG operators (Service Providers using the device for straightforward event coverage or the more complex occasional links). The following sections describe the control / command menu tree of the DSNG DBE 4110 encoder. Caution: When a parameter is changed by the supervision applications, the front panel display is not updated, it is necessary to validate the parameters.

4.5.3.1.2 - “Output” item
Figure 4.33: Parameters related to output Purpose: set the output signal. In the Output clock area Internally synthesised
The MPEG output signal rate is given by an adjustable internal frequency synthesiser. It is possible, using the Set command two lines below, to optimise the rate by minimising the number of null packets sent by the encoder. The calculation takes into account the values of the component rates generated by the device as well as the rates allocated to signalling and ECM. Notes: 1. If the TS output is exceeded, the component rate must not be increased. If this is the case, firstly reduce the component rate. It is necessary to increase first the TS output and then the component rate. 2. If the Set command does not take into account the Output clock changes when you modify the Max bitrate value. For example:

- Change the Max bitrate value, - Click on the OK button and close the window, - Open the window and click on Set command, - Validate the changes.
Optimal frequency
Minimum clock frequency of the TS for transmitting the defined service. This frequency can be calculated with the Set button. It can be useful to help recording the TS output on a server.
In the Maximum Bitrates area Signalisation
This value sets the alarm generation threshold and reserves the output rate required to send the signalling. When the equipment output rate is low, it is necessary to make adjustments to optimise the reserved rate. The maximum value is 3Mbit/s.
ECM
Used for alarm generation.
In the TS packet size area, the operator can choose the size of packets multiplexed in the outgoing TS. 188 bytes
This button corresponds to the standardised TS packet size, conforming to the MPEG2 ISO 13818-1: “Generic Coding of Moving Pictures and Associated Audio: Systems” standard.
188+16 bytes
The device adds 16 stuffing bytes after each 188 byte packet. This mode may be used when the device is connected to a satellite or cable modulator. The modulator then replaces these bytes by Reed-Solomon error correcting code. Note: When the ISMB board is used, TS packets must be in 188 + 16 form.

Figure 4.43: Parameters related to DVB signalling Purpose: set table broadcasting frequency. Repetition rates of DVB actual tables area This panel is used to set the recurrence of DVB (NIT, SDT, TOT, BAT, TDT, EITp/f, EITs) table transmission in the output signal. Notes: 1. When a table or sub-table is externally loaded with a defined repetition rate, it is no longer affected by these default values. 2.When a sub-table is loaded in an multiplexer to replace a previous one, the replacement actually happens when the previous equivalent sub-table has been transmitted in full (i.e. after the last section of the sub-table). In the meantime, the new sub-table is stored but not transmitted. In addition, each sub-table has to be sent at least once to avoid discontinuity of version numbers. Various side effects ensue: 47232437AK01 June 2003

- in the intermediate stage, the two sub-tables co-exist and take up space in the device buffers, - if another equivalent sub-table is loaded in the intermediate stage, there will be three sub-tables in the memory, - if EITs (with a very slow broadcast rate) are loaded very quickly, it is possible to end up with a number of equivalent tables at the same time which may require several seconds to clear. For example, when five EIT tables are loaded very quickly (with a repetition rate of 10 seconds), the last one loaded will be transmitted 40 to 50 seconds after loading. 3. Only the EIT_schedule 80 to 84 tables are supported by devices (equivalent to 20 days of programme guide).
Generate TSDT area The TSDT table is an ISO table, the contents of which are defined by DVB. This table is used in DSNG applications where editing of the SI tables in the field may be impossible due to operational problems (compliant with ETS prEN 301 210 standard). The TSDT is used to identify the transmitting satellite station. The station identification parameter entered here is displayed on the front panel of the encoder. Repetition rates of DVB other tables area This panel is used to set the recurrence of DVB other table transmission in the output signal.

For the Country field, a list of countries is given by default. But it is possible to type three characters for the country code which is not proposed in the list. The lists of default language and country codes can be customised to include additional languages or countries or restrict default lists to the most common choices. These lists can be customised by changing the content of the codes.ini text file in the DBS 2930 setup directory. When language or country codes are defined in this file, the DBS 2930 uses these instead of the default lists regardless of the version (French or English) of the DBS 2930. The order in which codes are declared sets the order in which they appear in the choice lists. The file format observes Windows .ini file syntax.
Example of a .ini file [country_code] FRA=France [ISO_639_language_code] est=Estonien fre=Français
The [country_code] section contains the country codes. The name of each key is the ISO 8859-1 three-character code for the country. Its value is the text to be displayed in the list of choices. The [ISO_639_language_code] section contains the language codes. The name of each key is the ISO 639 three-character code for the language.

Notes: 1. When the Pattern source is selected, the internal PLL is no longer locked onto the video input, but to a fixed internal frequency. In these conditions, the SDI audio source transmitted with the video signal could give rise to alarms due to synchronisation problems, thereby creating disturbance in the sound signal. 2. There is no test to check whether the same PID is used as the output PID of two transiting components. PID instructions are considered to be instruction opportunities and only apply when the components do indeed feature on input. If however, the two components were to exist at the same time, one of them would be stopped and an alarm raised.
Profile
Choice between MP@ML and 422P@ML.
The Multiplex parameters area has the following fields: PID
Identification of the TS packets transporting the video component.
PCR
Choice between • No PCR: the component does not carry the PCR, • Service PCR: the component is referenced to carry the service PCR. In this case, the PID of this component fills the PCR PID field in the Service dialogue box (Figure 4.61 page 240), • Contains a PCR: the component carries a PCR without being referenced to carry the Service PCR. In this case, each component of the service can carry the PCR. These facilities mean that in remultiplexing operations, a TV service containing one video and several audios may be split into one TV service and several radio services each containing a single audio only.

The Compression area has the following fields: Rate
value between 0.5 and 15 Mb/s if MP@ML. value between 0.5 and 50 Mb/s if 4:2:2 P@ML. The operator can now set a video bitrate lower than the minimum bitrate indicated in the DBE 41xx encoder technical specifications. However, in any case an input of under 0.5 Mbit/s is rejected. When exiting the video parameter editing screen, a warning message requests the operator to confirm settings. The message specifies the minimum bitrate recommended by NEXTREAM for information purposes (i.e. 2 Mbit/s).

The mode optimises video compression. In Film mode, encoding and motion prediction are forced to frame mode because there is no motion between the 2 interleaved fields making up the frame. In Video mode, encoding and motion prediction are forced to field mode. In Auto mode, the encoder itself sets the best mode (film or video) having analysed the two interleaved fields. Only auto mode is capable of correct processing of a 3:2 pull down film mode (60Hz).

reception of the WSS signal, the format is specified by the field Default value 4:3 or 16:9. Note: With an SDI source transporting WSS in digital form (DID/SDID), you must declare the digital WSS in one of the VBI components (see section 4.5.4.1.3 - Editing parameters of the VBI component page 264). In any other case, it is all done automatically.
• Automatic AFD: format assignment depends on the AFD (Automatic Format Description) information contained in the incident 4:2:2 video signal. In case of non-reception of the AFD signal, the format is specified by the field Default value 4:3 or 16:9. Note: The AFD, also known as ARD, was defined by the BBC. It is the modified "video index" (line 11 and 324 in 50 Hz and 14 and 277 in 60 Hz) which supplies, among other things, information on image format (4:3, 16:9). The AFD can only be received in a video from the SDI input. The Aspect ratio default value is used until the AFD data has been received. Once the AFD has been detected, the image format is determined by the AFD data. Unlike WSS, when the AFD data disappears, the image format keeps the format contained in the AFD (it does not revert to the default format).

Note concerning the audio source names from the SDI input. An SDI signal can contain up to 16 mono audio channels. Two mono audios constitute an AES/EBU channel. AES/EBU channels are grouped in pairs and each pair forms a group.

Comments: 1. SSEB board: The SSEB board includes 2 stereo audio compressors, thus enabling two stereo audios in the output signal (stereo audios 1 and 2). The possible sources for the each stereo audio are as follows: • the SSEB board SDI input; • the SSEB board analogue input. When the SDI input is selected, a group number must be supplied. This number identifies the group to which the stereo audio belongs. When the source of the two stereo audios 1 and 2 is SDI, SSEB board internal wiring requires both stereo audios to be taken from the same group (one de-embedder for each pair of stereo audios).

2. ATADI board (option N41HATADAK): When this board is present, the list of possible sources for the audio 1 and audio 2 components contains two additional options: • the balanced digital input; • the unbalanced digital input. When the audio 1 and 2 source is a digital input, ATADI board internal wiring requires both inputs to be of the same type (Balanced or Unbalanced). 3. AMuSE board (option N41HAMUBAK): The AMuSE board is now dual-standard, i.e. MPEG-1 Layer II and Dolby AC-3. It is capable of packetising up to four Dolby AC-3 sounds from external audio encoders, or up to four sounds in MPEG-1 Layer II standard It is not possible to combine MPEG-1 Layer II encoding and Dolby AC-3 packetising with the same AMuSE board. The four audio channels on the AMuSE board are configured in either MPEG-1 Layer II or Dolby AC-3. In both cases, for each audio, the source options are as follows: the AMuSE board SDI input; the AES balanced digital input; the AES unbalanced digital input. When SDI input is selected, a group number must be supplied. This number identifies the group to which the audio component belongs. Some restrictions apply: 1. When the audio compressor 1 and 2 sources come from the SDI signal, internal wiring of the AMuSE board requires selection of the same group for the two sources. This rule also applies to compressor 3 and 4 sources. The SDI source (with AC-3 audio) must be synchronous with the one sent to the video encoder (SSEB board). 2. When the audio compressor sources are AES digital inputs, internal wiring of the AMuSE board requires all AES inputs to be of the same type (balanced or unbalanced). When either of these sources is used, the external Dolby encoder must be genlocked through the synchronisation output from the REF OUT connector on the AMuSE board. 4. PATTERN signal: The audio test signal consists in the transmission of a 2100 Hz frequency signal at 0 dBFS (full scale level). Be careful when using the audio test signal, as it produces a very loud sound. Note: In pre-compressed AC-3 mode, the AMuSE board does not generate an internal audio test signal.

VPS automatic mode
In MPEG Layer II compression mode, VPS information contained in the incident 4:2:2 video signal can be used to control automatic selection of the audio mode and the bitrate. When automatic VPS mode is validated, the input values in the Compression mode fields are default values that are only applied in the absence of VPS information. Note: With an SDI source transporting VPS in digital form (DID/SDID), you must declare the digital VPS in one of the VBI components (see section 4.5.4.1.3 - Editing parameters of the VBI component page 264). In any other case, it is all done automatically.
Alignment level and Headroom For analogue audio source only: The maximum input level is the analogue level in dBU with input saturation. After conversion, a digital level of 0 dBFS is produced. Two parameters are used to set the maximum input level: alignment level and headroom. Alignment is the level in dBU which corresponds to 0VU. It can be set between 0 and 4 dBU in 1 dBU steps. Headroom is the difference in dB between alignment level and input saturation. It can be set between 8 and 20 dB in 1 dB steps. Physically, the analogue audio input saturation level corresponds to alignment level + headroom in dBU.

This parameter is used to adjust the phase of the audio component with respect to the video component. The additional delay is used to recover a correct lipsync when a non-standard decoder is used. The accuracy of the value in ms is not guaranteed. Do not use the additional delay to compensate bad audio/video synchronisation of the encoder service signal. Please reboot the DBE 4110 after changing the additional delay. The additional delay should remain set to 0, which corresponds to a correct lipsync (tested with an MSU 4422 decoder).

This change is only possible when an MPEG 1 Layer II coded audio component is attached to a service not containing any video component (radio service for instance). The Additional Delay parameter can then be set between –50ms and +350ms instead of 50ms/+50ms. The DBS 2930 performs the following checks: - when editing the parameters of an audio component, the value of the Additional Delay parameter is checked; - when adding a component to a service, addition of a video component is rejected if the service contains an audio component from an AMuSE board with an Additional Delay value of above 50ms.

The Component selection area is used for setting the injection parameters TS input and Input PID. Note: The incident PID is replaced by the one supplied by the Operating Station (see Figure 4.77 page 271).
The Incoming signalling area is used for programming the behaviour of the encoder with regard to incoming signalling. • If Dropped is selected, this means that the streamtype information and the descriptors contained in the PMT and the SDT input tables of the incoming TS stream are not kept. The Stream_type value of the first tab ("General") is taken into account and the Edit additional PMT info... and Edit additional SDT info... commands are used for adding new descriptors. • If Added to the local signalling is selected, this means that the stream-type information and the descriptors contained in the PMT and the SDT input tables are kept and added to the descriptors edited locally. The Stream_type value of the first tab ("General") is not used. Note: If a transiting service component is linked to a generated service via the "local" option for descriptor insertion, the list of descriptors mentioned will be associated with the component in both PMTs generated by the multiplexer (the descriptors associated with the component in the PMT of the original service are forgotten). In other words, the multiplexer only generates one context per component, and the transiting component is assigned the modifications made when it is used as a linked component.

4.5.4.2 - Advanced Functions 4.5.4.2.1 - Shared components A shared component is a component which is linked to two or more services in the SI/PSI tables. Actually data of a shared component are not duplicated. The elementary stream is just indicated by the signalling of different services. A typical application of shared components is a live information service. For instance this service could be a news service that displays stock exchange quotes on the TV set in real time. To be accessible from every service these data must be broadcast into each TS of the network and referenced by each service. There are three methods of implementation: Signalling

Figure 4.92: Principle of Shared Components In the first solution (case a), the elementary stream is duplicated for each service in the TS and is referenced as a private data component. The cost of this solution in terms of bandwidth is very high. The second way (case b) is to broadcast the elementary stream (ES) once in the TS. A private descriptor is used to reference the component. The decoder is able to interpret that descriptor and tune to the component. This solution is acceptable but not compatible with any remultiplexing operation since the component is not described in the SI/PSI signalling.

The last solution (case c) is to use the share component feature. The data are broadcast once and the component is described in SI/PSI signalling. Any type of component can be shared.
, Procedure 1. Select a service. 2. Select the Add components... command. 3. Consult the list of components. 4. Check the Show shared components box to display all the proposed resources (including those already used in another service). 5. Select the components to share in the list. 6. Click on OK. Shared components are displayed like the other components in the main window. This means they can appear several times in the tree view. Notes: 1. When parameters of a shared component are changed, all the items of the list referring to the shared component are updated. This means that each parameter of a shared component is identical regardless of the service except for the PCR. This parameter can have different values according to the generated service that uses it. When a shared component is removed from a service, it is not removed from other services. Actually only the reference to this service is deleted. But when a shared component is only referenced by one service, it automatically becomes a non shared component. The remove command works exactly as it does for a non shared component. 2. A shared component can only be scrambled locally if all the transmitted instances of this component belong to the same access group. Thus, when a component belongs to two services and scrambling is only required for one of the services, then the component is transmitted in clear.
4.5.4.2.2 - Ghost components Ghost components are components broadcast by an encoder that are not referenced in SI or PSI tables. To recover a ghost component the receiver must know its PID. Since the PID is not present in SI/PSI signalling, the receiver and the transmitter must have a non standard mechanism to exchange the PID. This could be a private

data descriptor or a private table. Ghost components are used by some networks for testing purposes or to generate non DVB/ISO streams. Notes: 1. Ghost components cannot automatically be transmitted at the remultiplexing stage even if the multiplexer is set to pass all services. They must be explicitly indicated to get through the multiplexer. 2. Ghost components cannot carry the PCR. 3. If a component is a ghost component (non indicated in the outgoing stream), It does not be associated to a service. If a component is declared "ghost component" issued of a SRV1 service on the tributary, and the broadcast of the service SRV1 is authorised without stopping the component, the component is neither a ghost component because it describes in the PMT of the service SRV1.
To avoid confusion for users who do not need this feature, the Ghost component item is hidden by default. To show this item and gain access to the ghost component facilities, select the Manage ghost components command in the pop-up menu of the Generated Services item.

All types of filtering are possible: • First level filtering: first level filtering provides global action on the TS input. The Unused command stops the TS input whilst the Used command lets the TS input stream through, applying the second, third and fourth level filtering conditions defined below. • Second level filtering: global filtering conditions may be defined (Stop all or Pass all) on each of the following three entities: services, EMM data, access control data. For both the Services and EMM data entities, additional filters can be used to authorise or drop individual services and EMM flows: Authorise a service to be transmitted or Drop a service and Authorise an EMM service or Drop an EMM service commands. Other facilities are also offered, e.g. • checking incident TS stream identity (not implemented), • selecting incident table processing mode, • authorising automatic reallocation of component PIDs in the event of conflict, • monitoring the TS input bitrate. Monitoring allows the TS input to be stopped if bitrate is exceeded with notification to the operator. • Third level filtering: the identification parameters for authorised services (service_id, service_type, service_name) and authorised EMM flows (EMM_PID) can be redefined. In addition, service components are filtered at this level; filtering may be global (Stop all or Pass all), or specific (Add a component or Drop a component). Other facilities are also proposed, e.g. • suspending or starting up transmission of a transit service, • attaching locally generated components to a transit service, • monitoring bitrates for incoming services. Monitoring allows incident services to be stopped if bitrate is exceeded with notification to the operator. • Fourth level filtering: all functions affecting components are grouped at this level, i.e.: • redefining a component PID. • suspending or starting up transmission of a transit component, • monitoring bitrates for incoming components. Monitoring allows incident components to be stopped if bitrate is exceeded with notification to the operator.

THOMSON DBE 4110 MPEG-2/DVB Encoder - User manual
The encoder load can be reduced by requesting that only part of the incoming signalling is managed. There are five modes available: No signalling: all signalling arriving on the input is ignored. When this mode is enabled, all filtering instructions are ignored as there is no analysis of signalling. Consequently, the filters placed on this input are not implemented. Data received on this input can only be used to define TS components. Default: the mode selected is the same as that set for output (see editing of encoder advanced parameters). ISO signalling: Only ISO tables are analysed. DVB tables are ignored (SDT and EIT). If the multiplexer is configured to generate a DVB output signal, the current SDT is generated by default by the encoder by automatic creation of service and service provider names. DVB restricted: ISO and DVB tables are analysed except for EIT p/f and EIT s tables which are still filtered. The current SDT table is produced from the data elements available in the current incoming SDT. DVB signalling: ISO and DVB tables are analysed. The SDT and EIT tables for each service are retransmitted if the filtering instructions authorise transmission of the service.

If the signal is scrambled, only the ECMs and their references in the signalling are removed.
In the Case of PID conflict area PID reallocation authorised
If a transit component PID comes into conflict with a locally generated service PID, the encoder reallocates another available PID value.
PID reallocation not authorised
If a transit component PID comes into conflict with a locally generated service PID, the encoder stops the component and raises an alarm to the operating terminal.
Notes: 1. Generated components have priority over transiting components. So, when generating a component whose PID enters into conflict with that of a transiting component, the latter is stopped (if reallocation is barred on the tributary) or its PID is reallocated. A transiting component linked to a locally generated service is not considered as a generated component. 2. It is advisable not to change the authorised/not authorised reallocation mode during normal operation and to always keep the same mode. In PID reallocation authorised mode, the way in which PIDs are reallocated is directly linked to the order in which they are detected in the incoming stream. It is therefore not surprising that reallocation can differ between a redundant device and its back up device. 3. The device accepts both services with a PCR carried by a specific PID and reallocation of the supported PID as required; however, one case of reallocation has not been solved. take the following example: S1 (Vid = 200, Aud = 201, PCR = 400), S2 (Vid = 300, Aud = 301, PCR = 400), S3 (Vid = 400, Aud = 401, PCR = 400). If no specific reallocation instruction is given, the output signal will be correct. But if video 400 to video 500 reallocation is required, the output signal will be as follows: S1 (Vid = 200, Aud = 201, PCR = 400), S2 (Vid = 300, Aud = 301, PCR = 400), S3 (Vid = 500, Aud = 401, PCR = 500). In fact the result depends on the arrival and processing order of the PMTs. The problem does not arise if the PCR is not carried by a component.

" Services and data flow window
This window may be accessed by clicking on or choosing the Services and data flow command in the drop-down View menu in the menu bar. The window consists of two sub-windows. The first sub-window displays the input services and rates on TS input. The second sub-window displays the output services and bit rates supplied by the encoder. Component bitrates are measured every second in the device. The bitrates fed back to the operating station appear fixed whereas in reality they fluctuate.
Figure 4.123: "Services and data flow" window The tree view has three levels: • at level one, the encoder (in the "Input services..." subwindow) and the Transport Stream conveying the set of services (in the "Output services..." subwindow). It shows the maximum rate allowed depending on the output frequency of the encoder and the size of the TS packets (see section 4.5.3.1.2 “Output” item page 194) as well as the current rate. • at level two, the services of the selected device with data flow information. The representation of services gives the name of the service, service identifier and service data flow. • at level three, the components of a service with data flow information. The representation of components depends on their scrambling (the icon is greyed out if the component is scrambled). Information given for components includes component type (Video, Audio, etc.), PID (in decimal and hexadecimal) and component data flow. 47232437AK01 June 2003

4.8 - {EVENT LOG} APPLICATION
4.8.1 - Principles of the {Event Log} application The purpose of this paragraph is to list all the functions of the {Event Log} application.
4.8.1.1 - Event " Event types The event types displayed are as follows: • • • • • • • •
rising alarm; falling alarm; reboots; device connections; device disconnections; device configuration changes (activations); service switching (to replacing) by INBAND command; service switching (to regular) by INBAND command.
" Paired events Some events can be grouped into pairs. Paired events are: • rising and falling alarm; • service switching to replacing and regular by INBAND command; • setup and release of connections with devices.
" Parameters displayed Each event is displayed with the following parameters: • • • •
a record number; an event identifier (event_id); a sub-identifier (event_extension); the name of the device which caused the event;

• the text describing the event; • the date and local time of event occurrence; • the duration (this parameter is significant only for rising alarm events).
4.8.1.2 - View configuration functions These functions facilitate event viewing by displaying just some of the information according to operator-defined criteria.
" Sorting Sorting consists of changing the order in which events are displayed in the list. Two sort options are available: • sorting by record number; • sorting by date and time.
" Filtering Filtering consists of defining events to be displayed on the screen. Those displayed satisfy the following criteria: • they belong to event identifier lists; • they come from given devices; • they fall between two dates set by the Operator.
" Masking This function is used to mask the display of certain untimely events. These events are not deleted, they are simply no longer visible.
" Searching This function is used to move the cursor in the view of the current event to the event with which it is paired. If the search fails (the paired event is not present or not visible on account of the filter applied), an error message notifies the operator that the command has failed.
4.8.1.3 - Event exporting It is now possible to export the list of events to a text file. Any given event is represented over one line, each field of the event being delimited by a tabulation. 47232437AK01 June 2003

" Calculation of durations
The Tools/Calc durations... command in the menu bar is used to calculate the duration between a rising alarm and a falling alarm or the next device reboot. Given the time required for the calculation, this command is only available on backup files and the Operator has to confirm command execution. Once the calculation has been performed, the duration of each event is displayed in the Duration column in the main window. Durations are stored in the event log file. It is not necessary to recalculate duration each time a file is opened. Note: When the calculation proves impossible (if the falling alarm is not saved in the same file) or duration is insignificant, the Duration column remains blank.

4.10.3.3 - LTW_offset Set LTW_offset flag when service PCR (Yes:1 No:2) (x)? This parameter tells the encoder whether or not it should add the LTW offset value to the video when the video is carrying the PCR. Default value = 1.
4.10.3.4 - SPE (SuperEncoder) switch source mode SPE switch source mode (same as old board:1 same as new board:2) (x)? This parameter is used to choose the SuperEncoder board switch mode: • if you have an old version of the board (version AG), mode 1 must be selected • if you have a recent version of the board (versions AH, AJ or AK), mode 2 must be selected. However, if the video input signals are not synchronous then interference caused by the switch appears on the picture. In this case mode 1 can be used to reduce interference.
4.10.3.5 - VBI stream type VBI stream_type with MT lines (ISO:1 BARCO:2) (x)? This parameter is used to choose the stream type value used for Monochrome transparent VBI components. The (ISO) default value is the 0x06 standardised value. The other possible (BARCO) value is 0x92 which corresponds to a BARCO proprietary value used for Monochrome transparent lines. All Monochrome transparent lines generated by the encoder have either a 0x06 or 0x92 stream type value and no combination is possible. A descriptor must be added to the PMT. See {Technical Configuration} application section Editing parameters of the VBI component page 264.
4.10.3.6 - LDSChurch mode LDSChurch mode -ignored when SPE board is declared- (ON:1 OFF:2) (x) ? This mode only concerns operation in 60Hz mode. When the mode is set to ON, the active lines in fields 1 and 2 are moved up a line. The first active line is therefore line 21 for field 1 and line 284 for field 2 (the first line being line 1). This mode is used to transmit the sub-titles as a useful part of the video signal. THOMSON DBE 4110

On a DBE 4130 or 4150 Encoder featuring a SuperEncoder board, this parameter is not acknowledged and the lines are not moved up. The SuperEncoder board is detected when the device is turned on. Checking the "closed caption" box in the DBS 2930 Operating station, video component parameters VBI tab is unnecessary. If the box is checked, the sub-titles will be transmitted in the video stream twice (as user data and in line 21). Default value = 2
4.10.3.7 - ABSAT mode ABSat mode (ON:1 OFF:2) (x) ? This mode, designed for the DBE 4130 Encoder, is used to modify Video encoding so that it is compatible with Philips "G+2" series decoders. When ABsat mode has been selected: - the VBV delay value is calculated and sent for each picture, - the default quantisation matrix is systematically included for each I-picture. The DBE 4130 Encoder in ABSat mode remains DVB compliant. Notes: - operation in ABSat mode is not guaranteed with decoders other than Philips "G+2" series decoders. - ABsat mode has been designed for the DBE 4130 Encoder. Operation in ABsat mode is not guaranteed for other DBE 41XX Encoders. - ABsat mode only operates in 50Hz mode. - the Helper Channel application, which is a specific function of the DBE 4120 Encoder, does not operate in ABsat mode. Default value = 2
4.10.3.8 - Multichoice-D1 mode Multichoice-D1 mode (ON:1 OFF:2) (x) ? This mode implements an MPEG-2 syntax specifically for the video component. - Each PES contains a single GOP, - The PES is formatted as follows:

- the DataAlignmentIndicator bit is set to 1 (PES payload begins on a video "Elementary Stream" header), - the PES data length field uses 10 bytes instead of 11 for I and P-pictures (a 0xFF stuffing byte has been deleted). - There is no stuffing byte between pictures at "Elementary Stream" level (no 16-bit alignment), - There is no stuffing "Elementary Stream" (minimum payload at TS level). When the mode is set to OFF, each PES contains a picture, the DataAlignmentIndicator is set to 0, the PES data length field uses 11 bytes, there is a number of stuffing "Elementary Streams" (required to align the start of the PES with the start of the TS packet) and there is no longer 16-bit alignment. Default value = 2.
4.10.3.9 - Foxtel 6dB uplift Foxtel 6dB uplift (ON:1 OFF:2) (x) ? This mode adds +6dB of gain to audio samples encoded in MPEG-1 by the SSEB board. The audio is doubled before peak limiting and encoding. All SSEB board audio inputs are concerned: - SDI, - Analogue audio converted to digital. All audio components encoded by the SSEB board are affected. AES/EBU audio signals generated by the ATADI board are affected. The 2.1kHz test signal, 0dB generated by the SSEB board is not affected. Audio signals generated by the AMUSE board are not affected. The uncompressed audio mode (DBE 4120) is not affected. Note: you are advised not to use Foxtel mode and a 384Kbit/s bitrate at the same time, as in this case audio quality is not guaranteed. Default value = 2

4.10.3.10 - Closed Caption type Closed Caption type -only with DBE4130- (DVB/ATSC:1 DVB/DSS:2) (x) ? In 60Hz mode, the DBE 41XX can extract line 21 sub-title information (the first line being line 1) from the video input signal (if the information is modulated and not binary) and can insert it into the "Video Elementary stream" according to the ATSC A/53 standard. This is done when the "Closed caption" box is checked in the Technical Configuration application, video component advanced parameters, VBI tab. With a DBE 4130 Encoder, the sub-titles can be inserted into the "Video Elementary stream" according to two standards: DVB/ATSC: 1 = "DVB / ATSC A/53" standard, DVB/DSS: 2 = "DTV95MDB-04, DirectTV MPEG1 and MPEG2 video stream specifications for IRDs, version 2.1" standard. This parameter does not affect the MPEG-2 TS layer or the PSI and SI tables. This function is only implemented on DBE 4130 Encoders. On other DBE 41XX Encoders, the parameter value is set to 1. Default value = 1 (DVB/ATSC A/53)
4.10.3.11 - Extended-data insertion (line 284) Extended-data insertion (line 284) -only with DBE4130- (ON:1 OFF:2) (x) ? Line 21 of the second field (i.e. line 284) can contain information similar to sub-title information known as "extended data services". This parameter can have two values: 2 = OFF 1 = ON, the "extended data services" data is extracted from the video input signal (only in modulated form) and inserted into the "Video Elementary stream" syntax in the same way as the sub-titles. This function is only implemented on DBE 4130 Encoders operating in 60Hz mode. On other DBE 41XX Encoders, the parameter value is set to 2 (OFF).

5.1 - FAST-DSNG
A DSNG system is used to transmit pictures and sound between the site of an event and a professional television (producer, television channel, etc.). The signals are produced at the site of the event from a mobile system containing the equipment required to produce video and audio signals and transmit them to a site for broadcast via a satellite link. The size of the DSNG system can vary considerably, depending on the coverage desired for the event and the mobility required. A DSNG system can just as easily be a camera, encoder, satellite modulator/up-converter which can fit into one or two flight cases, as several O.B. vans containing cameras, mixing desks, encoders, cables, etc. Those involved in DSNG systems are: - satellite operators; - satellite antenna manufacturers; - satellite modem manufacturers; - manufacturers of power amplifiers and RF systems; - video encoder/decoder manufacturers; - audio encoder/decoder manufacturers; - supervision system manufacturers; - systems integrators. "
"
Setting up DSNG communications
Setting up a satellite link requires that a procedure defined by the satellite operator be followed: 1. The satellite operator notifies the DSNG operator of the: - position of the satellite; - transmission power; - uplink frequency; - bandwidth; - downlink frequency after frequency translation by the satellite. 2. The DSNG operator contacts the reception station by telephone and begins a connection procedure. 3. This operator directs the satellite antenna and transmits a low power, pure carrier on the uplink frequency. When communication occurs on frequency C-band, spectral inversion may be required. 47232437AK01 June 2003

Chapter 5 5.1 - Fast-DSNG
4. The reception station confirms reception of the signal. 5. From this moment onwards, the DSNG operator can no longer interrupt the signal transmitted to the satellite because signal absence may be interpreted by automatic frequency allocation systems as availability of the frequency and bandwidth. 6. The DSNG operator increases the power and sets the modulator to modulation mode. 7. If the operator has a decoder and his geographical position enables him to receive the transmitted signal, he checks that the transmission is being sent correctly. In the event of a problem, he may also check the signal at the modulator output by using the L-BAND output.

Purpose
This software is supplied as standard with DBE 4110 encoders. The main purpose of this software is to facilitate input of the parameters required for setting up a satellite link on the encoders and the modulator. Configuration using the graphic interface is very simple. The operator can display all the transmission parameters together with the composition of the transmitted signal on six screens. Configuration changes are optimised by reducing operator actions. The software operates on a PC (laptop) with standard performance, featuring: - Windows 95, 98 or NT operating system; - Ethernet 10BaseT interface; - 640x800 colour screen with 256 colours; - pointer device (mouse or other). The application is only available in English.

5.5.3.1 - Transmission parameters Transmission parameters are found in two areas. The upper area is used during the procedure for setting up satellite communication. The lower area is used for configuring the modulator. In the upper part, four buttons control the modulator output: • In Off position (key F9), the modulator does not transmit a signal. The operator can then set the modulation parameters (frequency, bandwidth, etc.) in the lower area. The application does not send any configuration to encoder. • In Ready position (key F10), the modulator does not transmit, the parameters can no longer be edited. The software sends the configuration to the encoders. • In any Pure carrier position (key F11), the modulator transmits a pure carrier with the level displayed under the button. The parameters entered in the lower area can no longer be edited. • In Modulation position (key F12), the modulator transmits a modulated signal with the level set to High. In this mode, level and modulation parameters can no longer be edited. Note: If the system is disconnected, all the devices remain in the initial state. The parameters displayed in the lower area can only be modified in the Off position (key F9). Access is unauthorised in the other positions and the cursor indicates this by changing its form ( ). The Symbol rate and Bandwidth parameters are interlinked by a formula that involves the Convolution parameter. Each time the operator changes one of these three, the Bandwidth and/or Symbol rate parameters are recalculated immediately. Thus, if the operator enters the symbol rate, the application will immediately calculate the bandwidth for information purposes, or vice versa. The calculated value will be displayed in the process. Note: If a bad format is chosen, the bandwidth cannot be calculated and the field remains blank. An error message is displayed.

5.5.3.2 - Parameters linked to encoder control and signal content In Figure 5.3, the right-hand area of the dialogue box is dedicated to encoder control and the content of the transmitted signal. The button in the Components area title is used to quickly modify the service-id parameter.
Figure 5.4: Service Id Editor
It displays two lists of available components (one list per encoder). The content of the list depends on the software and hardware options installed on each encoder. Above each list, an alarm symbol appears in front of each encoder name. Its appearance depends on alarm status: • Green: no alarm, • Orange or red flashing: alarms have occurred. In the list, a check box in front of each item allows a component to be inserted into the signal transmitted to the satellite. By clicking these boxes, the components are inserted into, or removed from, the signal one by one. If the Video bitrate automatic adjustment in the Transmission panel is checked, each time a component is inserted into or removed from the signal, the application recalculates the bit rate of the video components automatically to ensure optimum use of the bandwidth. For systems with two encoders, the rate allocated to each video component is always identical. For advanced use, a button located under each list allows access to parameters of the component selected in the list. This screen can be used to modify the PID, profile or other advanced parameters. The presentation of the parameters in these screens is identical to that of the DBS 2930. To change video parameters, the procedure is: 1. Select the component, 47232437AK01 June 2003

Figure 5.15: Preset panel
This panel is used to configure each encoder with the configurations saved in the encoder memory, save configurations and delete backup configurations. Two types of memory are defined for DBE 4110 encoders: • the authorised read and write memories that can be programmed by the Operator using the Fast_DSNG software. • the authorised read-only memories that are programmed at the manufacturers. They contain the standard predefined configurations. The contents of these memories cannot be changed by the Operator. A list is displayed for each encoder in which each line represents a memory identified by a number or letter (1 to 8 for read and write memories; and A, B, and C for read-only memories). Each line also contains the name of the archived configuration and the memory status (Empty, Read only or Used). No name is shown in the second column when a memory is empty.

Three buttons are also available to: • copy the current encoder configuration onto the selected memory (Save button); • activate the configuration from the selected memory (Recall button); • delete the content of the selected memory (Clear button). Note: the value of the parameters recognised by the factory set configurations A, B and C are identical to those described in section 4.5.3.6 - Archived configurations.

5.5.8 - Dynamic behaviour This section contains the software specification elements that are liable to change.
5.5.8.1 - No connection On starting up the application, the software attempts to set up a control/command link with the main encoder then with the second encoder. As long as all connections (one or two depending on the configuration) are not set up, the configuration parameters are not displayed. As long as communications are not set up, the encoder parameters in the Transmission, Alarms, Scrambling and Information panels are masked.
5.5.8.2 - Setting up a connection As soon as all the connections are set up, the software displays the current configuration. If the encoder does not know how manage the current configuration, it sends a message and proposes another standard configuration. • For a configuration with two encoders, the following tests are carried out: - If the Main encoder does not feature the N41STSIN option, communications are broken and a message is displayed; - If the Main encoder features the N41STSIN option, the TS input configuration is forced to allow all the services through.
• When an external signal is used on the TS input, all the services pass through. Once the tests have been carried out, the encoder configuration is displayed on the software screens. Subsequently, the alarms are regularly requested from the device and displayed in the Alarms panel.

Chapter 6 6.1 - Device connection problems
6.1 - DEVICE CONNECTION PROBLEMS
Connection problems are often difficult to solve as causes are numerous and varied. A malfunction may be caused by the network being incorrectly set-up on the PC, a wiring problem or damage to a non-responding device. The aim of this section is to provide a procedure that can be followed to solve these problems in a minimum of time. When the DBE 4110 is signalled as not responding, proceed as follows: 1. Check that the DBE 4110 is operational and that the front panel is working, by moving around the menus. 2. Check that the IP address assigned to the device on the PC in the {Equipment Installation} application matches the one assigned to the device displayed on the front panel in the Other/Tools/IP Address menu. 3. Check that the DBE 4110 responds to network prompts; use the Ping IP address command in an MS-DOS window. If the device responds, skip the next paragraph. 4. Check the value of the subnet mask in the network set-up panel on the PC; the subnet mask identifies the part identifying the subnet in the IP address; like an IP address it consists of 4 numbers separated by "."; if the device address is not in the subnet, the device will not be accessible. 5. Check the cables with the ohmmeter; Ethernet cables are quite fragile and connector crimping may be faulty.

Chapter 6 6.2 - Inspecting the power supply fuse
437
6.2 - INSPECTING THE POWER SUPPLY FUSE
If the "POWER" LED on the front panel is off, check the following in the order specified: 1. Check that the ON/OFF switch is ON. 2. Check the mains power supply source. 3. Reset the mains switch to OFF and disconnect the power cord. 4. Open the fuse holder on the switch base.
Fuse holder
5. Measure the fuse value with an ohmmeter. - If a fuse is faulty, contact the NEXTREAM Customer Service. A faulty fuse indicates that the product is damaged. You are therefore not advised to simply change the fuse. Please have the product inspected by a qualified member of NEXTREAM maintenance staff. - If the fuse is not faulty, another fuse in the power supply drawer may be faulty. To inspect this fuse, the unit requires dismounting and hence comes under a higher maintenance level. The procedure is not described in this manual.

6.3 - MISCELLANEOUS PROBLEMS
6.3.1 - Fan life expectancy The DBE 4110 has built in fans with a life expectancy of roughly 7 years at 30°C (6 years at 40°C). When your DBE 4110 reaches this age, fans will need to be replaced; please, contact NEXTREAM After Sales Service.
6.3.2 - Front panel LCD blank If the DBE 4110 is on and the front panel LCD is backlighted but does not show any indication or shows only four rows of black blocks, check that the contrast is properly set.
6.3.3 - Default analogue video input In the case of a device fitted with a DPSN board, the choice analogue video input PAL/SECAM (50Hz) or NTSC (60 Hz) should be available. If not, check that the DPSN board has been declared present ("Other/Tools/Option/Hardware").
6.3.4 - Autotest problem When a device cannot exit the autotest, try to clear the memory. To do this, switch off and set the rotary switch (on the RSMAINT board, if present, if not, on the SSEB board) to position 5. Switch on, wait 1 minute, switch off, return the rotary switch to position 0, and switch on. However, all the configurations (the current one and those saved) will be lost.

6.3.5 - Recommendations when using the MSU 4440 decoder Picture freeze: • A PCR component must be generated. • If "PSI OFF" decoder mode is used, check that the PCR PID is correct (generally the video component PID). • The recommended value of the V_PTS offset is 400 (menu "CHANNEL #1/IRD CONFIG/V_PTS=400"). This value is mandatory as specified in the decoder user manual. Picture chroma incorrect, colours not stable: • The 27 MHz clock generated by the decoder is jittering: its internal PLL is not locked. Check that the PCR PID is correct (PID of another service present in the input multiplex) or verify that the PCR is present.
