Nera’s Product – Mobile Receiver (Mobile Set Top Box)

Current Product Development Nera had recently completed developing and testing a new generation of mobile DVB-T diversity receiver and had carried out a number of field trials in Singapore, Norway, UK, France and Germany to evaluate the use of COFDM modulation and maximum ratio combining or MRC technology. The end result was the introduction of the first diversity receiver for mobile DVB-T. The mobile digital diversity receiver uses two antennas, and it combines the two signals it received to achieve good reception performance. The advantages of the mobile digital diversity receiver is that it offers a sensitive and dual (IF and RF) automatic gain control (AGC) offering more than 70 dB dynamic input range. This receiver provides a better and dynamic FFT positioning, accurate channel estimation for high Doppler frequencies and as well as FFT leakage compensation and equalization. Thus, drastically improve the receiver’s reception capability and performance when compared to the single-tuner receiver. Below is a brief overview of Nera mobile digital diversity receiver: -

Overview The diversity mobile receiver is DVB compliant MPEG-2 reception of broadcast up to Main Profile @ Main level. The diversity mobile receiver comes with controls for setting the receiver. By the controls the operator is able to select channel, modes of the DVB-T and the program for the MPEG decoding part of instrument. The default for DVB-T setting is an automatic mote in this mode the instrument will search for the right combination of parameters. However, for special application a manual setting is available. When locked to a signal the instrument will display the number of MPEG channels carried in the transport stream. The instrument is designed for 9V to 36V operations, in use for mobile transportation. The front panel controls can support stereo volume control for analogue audio output.

System Capabilities 1.1 RF The diversity mobile receiver works in the RF frequency range from 470 to 868 MHz or from Channel 21 to Channel 69. At input level from 25 dBuV to 115 dBuV, with input impedance of 75 Ohm, the diversity mobile receiver is being optimized for mobile environment. 1.2 Modes The diversity mobile receiver operates in the DVB-T environment at: • IFFT: 2k and 8k • COFDM: All modulation modes, code rates and guard interval defined by the DVB-T standard 1.3 Features The diversity mobile receiver comes with automatic program loading via scanning installation.

Nera’s Project Reference - TVMobile

Project Background TV Mobile has deployed a digital terrestrial television broadcast network in Singapore. A. single-frequency network (Channel 37) B. main transmitter plus nine fill-in sites to give 99% coverage C. Two video streams D. 2k carriers, 16QAM modulation for 'rugged' reception on-the-move E. 1/2 forward error correction rate, 1/4 guard interval F. audio also carried on conventional FM for individual reception on portables G. multiple LCD screens on 1500 buses H. on-air February 2001 I. programme services operated by MediaCorp (MCS) Nera was engaged by TV Mobile Pte Ltd as the main contractor to build and commissioned the first commercial mobile DTV system in the world. The digital TV Mobile channel was officially launched in 14 February 2001. Part of Nera’s contract was to plan, design and build the multiplexing and transmission system for Singapore's mobile digital TV service followed successful trials in 2001. Initially the most robust but least efficient form of COFDM modulation was used (QPSK). This produced extremely reliable reception, even to the extent that passengers were unable to appreciate the 'difficulty' of providing off-air TV pictures on-the-move! For the permanent service, higher-order modulation (16-QAM) will be used to increase the capacity of the system while still maintaining robust reception. For fixed-aerial reception (as in the UK), 64-QAM modulation is more usual, allowing even more program streams but with a consequent loss of robustness. As is often the case, audio provides many challenges in the TV environment. On the buses, audio was distributed through small speakers situated around the bus interior. With the inevitable range of individual preferences, audio level could be a real problem. The audio channels were therefore also distributed via conventional FM transmitters allowing independent reception through existing portable devices. To install a bus takes one team of 6-8 men one night to complete. To equip 1500 buses clearly a large and well-planned multi-team installation schedule was involved, and Nera has successfully managed that! During the TV Mobile project deployment, Nera had developed and manufactured the world first mobile digital receiver and dc-to-dc converter to be installed in the SBS bus together with bus antenna, pre-amplifier, audio amplifier, LCD monitors, audio speakers and other necessary cabling and supporting accessories.

Though along the way there were teething technical problems in the mobile digital receiver development, Nera was able to overcome all the technical difficulties and delivered the complete digital television reception systems for 1500 buses on schedule. After the successful development of the world first, mobile digital receiver for the public SBS buses of the TVMobile project, Nera has moved on to develop even more mobile digital receivers. The new generations of mobile digital receivers are built with enhanced performance and with value-added features to be deployed in other transportation platform such as car, boats, outdoor eating places and more. Today, Nera already have five generations of mobile digital receivers, each with improved reception performance and size reduction to be fitted in the space constraint vehicles.

We have made the assumption that Media Prima will make its own provision for either the optical fiber or microwave network link connectivity between the main system headend and the various distributed transmission sites. The preliminary DTTV solution design in this proposal comprise of a functional DVB-T system with the main system headend located in Klang Valley selected as the main site. One corresponding DVB-T transmission site will be connected via the assumed provided telecom fiber network from the main station headend, which will function as the pilot test site. The budgetary pricing that is provided in this proposal hence comprise of one main Headend system and one remote distributed Transmission site in broadcasting the digital signal via terrestrial means based on DVB-T standard. The proposed single distributed Transmission site serves as a pilot site for other subsequent distributed terrestrial transmission sites to be added in extending a wider coverage of DVB-T signal to the identified western part of Malaysia. Nera is not able to determine the actual number of distributed transmission sites at this preliminary design proposal stage prior to conducting further site surveys and thorough RF coverage prediction studies and analysis. Nevertheless, Media Prima can base on the single pilot transmission site costing given in this proposal in multiplying by the number of additional required distributed transmission sites to provide an estimated total budgetary pricing. Note that this assumption is only applicable if the link between the Headend and selected remote transmission site is via the fiber network infrastructure. Costing for other means via microwave or satellite link between the Headend main site and the respective transmission sites will be different. The proposed DTTB solution is based on Single Frequency Network (SFN) design.

Technical Architecture Description

4.2.1

General System Overview The Digital Compression system consists of a single Main Head End and 1st Transmission site over a Telecom Fiber Network. The Digital Compression system is responsible for grooming the channels required for the DVB-T bouquet. It is responsible for scrambling the new MPTS and for converting them into the telecommunication system. It has been assumed that Media Prima will provide the optical fibre network connectivity between the main headend and the transmission site(s). Depending on the signal loss of each component, it might be possible to add an optical amplifier. The diagram below shows the functional parts of the system:

Figure 4-1: DTV Compression Block diagram

4.2.2

System description 4.2.2.1 Equipment The Digital Terrestrial TV Head-end includes the following parts: 4.2.2.1.1

Input signals and Transrating

Page 16 of 16

The 20 unscrambled SPTS from the compression platform will be connected to the Digital Terrestrial TV platform. The number of MPTS may be increased depending on Media Prima needs by adding input card within the Transrater. The role of the router is mainly to ensure the routing (in case of the transrater failure) of the signals source to the redundant encoder inside the pool. It also allows a flexible distribution of the sources to each pool of encoder. Patch panels are located before the inputs and after the outputs of the routers to offer a manual redundancy of the grid in case of router failure.

4.2.2.3.2

Multiplexing

The MPTS Output of each master transrater is then scrambled by the Multiplexer. The SI/PSI data is inserted by the multiplexer as well. They are connected through an ASI router, which handles transraters and Multiplexers redundancy. Each multiplexer offers 4 identical DVB-ASI outputs:

• •

The 1st ASI output is connected to the SFN adaptor and then to the telecom adapter XNA through a router. The 3 other remaining outputs are kept free for other purpose (additional monitoring for example).

The output 3 & 4 can be unscrambled with the related software option. 4.2.2.3.3

SFN adapter & GPS receiver

Each MPEG2/DVB-Transport Stream ASI signal coming from the pool of multiplexers is connected to SFN adapter through an ASI router. SFN adapter is necessary for the synchronisation of DVB-T Transmitter operating as a Single Frequency Network. These SFN adapters compute GPS time clock reference and control information useful by transmitter to synchronise the modulation process. The two SFN (normal and redundant) are connected to ASI router, which manages redundancy. 4.2.2.3.4

Telecom adapter

Each MPEG2/DVB Transport Stream ASI signal coming from the pool of multiplexers is connected to the telecom adapters through an ASI router. Each telecom adapter (XNA) multiplex the 3 multiplexer outputs to constitute a 155Mb/s G703 signal feeding the optical fibre up to the Transmitting site. An optical splitter 1:8 gives the ability to duplicate the optical signal towards two fibres where optical switch is not needed.

4.2.2.4 Signal Flow Terrestrial Transmitting site 4.2.2.4.1

Telecom adapter

The two XNA (normal and redundant) are connected to an optical splitter from the Telecom Network, and deliver 3 pairs of redundant MPTS- DVB-T ASI streams from the Main Headend. Each MPTS pair (MPTS main & redundant) is connected to a dual inputs ASI of the modulators stage of the Transmitter. 4.2.2.4.2

The C&C is assumed to be exchanged through out of band the Media Prima WAN Network e.g. ISDN links or any other means to interconnect central Head-end and distribution sites IP networks. (solution presenting the best availability with 2 separate transmissions links between the Video/Audio and C&C data).

4.2.3

Redundancy 4.2.3.1 Redundancy policy At the Transrating/grooming level, the redundancy is performed on a 3+1. At the multiplexing level, the redundancy is performed on a N+1 basis for each group of equipment. We have considered 1 pool of 3+1 multiplexers. At the SFN Adaptor level, the redundancy is performed on a 1+1 basis. The redundancy of the XNA is performed on the 1+1 basis. The MCCs are secured in a “cold stand by” mode. This redundancy is selectable in automatic mode. More details on redundancy mechanism are given below. 4.2.3.2 Redundancy architecture The redundancy architecture is based on routers at each stage or the system: ASI (encoders output), ASI (multiplexers output) and optical interface (XNA output). The C&C equipment is able to manually or automatically manage the N+1 redundancy of the encoders, multiplexers and network adaptors. It will perform the re-routing of the signals coming from the ASI router to the redundant equipment up to the redundancy switching unit. The configuration setting of the redundant equipment is automatically loaded (mirroring function). The MCC is equipped with the automatic redundancy feature, which allows it to perform redundancy without referring to the C&C equipment that's why even is case of the PC's failure, the automatic redundancy is performed. Using this configuration, the platform can support multiple failures. 4.2.3.3 Redundancy mechanism 4.2.3.3.1

Redundancy of SFN

In case of failure of a SFN, the video inputs are rerouted to its dedicated backup SFN, which has the same configuration already loaded. Even in manual configuration, all these operations are done automatically by the system, the operator's action is a simple click on the C&C PC. 4.2.3.3.2

Redundancy of the multiplexers / transrater

In case of failure of a multiplexer, all input ASI signals are rerouted to the backup multiplexer, the configuration of the failing multiplexer is loaded on the backup multiplexer and the output of the backup multiplexer is re-routed to the correct input of the Modulator. Even in manual configuration, all these operations are done automatically by the system, the operator's action is a simple click on the C&C PC. 4.2.3.3.3

Redundancy of the network adaptor

In case of a network adaptor failure, the transmitter will be able to detect the loss of incoming signals and then switch to the backup.

4.2.3.3.4

Control & Command PC failure

No data are needed to be stored on the PC. Configuration files are useful if the system needs to be reinstalled (after accidental deletion of part of the configuration due to an operator errors). We recommend to copy these files on a floppy disk and to have the same files on the back up PC. If the PC fails, there is no impact on the system. The system runs as before, with redundancy, with ECM, EMM injection. 4.2.3.3.5

MPEG Channel Controller failure

The MCC stores the complete configuration of equipment under its control. This configuration is stored on a removable PCMCIA memory board. If the MCC fails, the system is still running but no redundancy action can occur. It is important to point out that the multiplexer, in case a break in the communication with MCC keeps the last correct ECM it has received and continue to work with it. So, apart from below, any MCC failure will not have any impact on the service given to the customer: • If there is another failure that requires redundancy action • If something changes in the commercial conditions of one or more services. Nera proposes to have a standby unit installed in the racks, pre-cabled, and having the same IP address as the nominal MPEG Channel Controller. This back-up unit is switched off under normal operation.

CONDITIONAL ACCESS SYSTEM

6.1

System Requirement 6.1.1.1 Provide a Conditional Access management system that is able to centrally perform dynamic control, updating, and generate cross referencing of subscriber’s access rights to individual broadcast services and products. The sms gateway interface allows the SMS to dynamically control and update individual smartcard profiles. The SMS can be integrated to query the CAS on which products are assigned to specific smartcards. 6.1.1.2 Must be capable of provisioning access and update of profiles for individuals, groups, or all of the subscribers. The sms gateway interface allows the SMS to address individual smartcards or send global commands (addressing all subscribers). Group provisioning is used by the internal Positive Addressing system. 6.1.1.3 Should provide suggestions or methods to improve the efficiency of the provisioning operations and administration, such as through the use of batch processing, pre-enablement, or bar codes. All methods of improving the efficiency of the provisioning operations are heavily dependant on the Media Prima business model and its mode of operations, and also on the capabilities of the SMS. The set of commands available to the SMS offers many control options, allowing the SMS to send the absolute minimum number of commands in each individual case, for example, when STB are recycled. Such optimization of sent commands require knowing the details of the Media Prima business model, what happens when to STB, etc. Other options are to have smart card sent to the STB manufacturer, so that both items are already packaged together. The STB manufacturer can send a file containing the STB and smart card ID pairs packaged. Another mechanism to consider is self-provisioning, where an application on the STB communicates with the SMS to enable services, correct addresses, etc. 6.1.1.4 Support the allocation of new digital packaging by groups, categories and bouquets. The product line-up for the terrestrial offering can be created and managed. The terrestrial PayTV channels can be considered as separate channels, allowing a completely separate product line-up for the terrestrial offering. 6.1.1.5 Must provide smart card and subscriber details management. Smartcard details (smartcard serial numbers, credit information, subscriptions and pay-per-view booked) management is provided. Some subscriber details like addresses and billing information must be managed in the SMS. 6.1.1.6 Support pre-booked and impulse Pay-per-View. Pre-booked Pay-per-view is supported as per existing system. Impulse Pay-per-view requires a return path on the STB. 6.1.1.7 Should be upgradeable to interface with middleware and applications system to support payment and authentication for t-commerce, ebanking, online billing and other interactive services. 6.1.1.8 Nagravision Conditional Access System currently does not support a “chaining” mechanism, which allows the transfer of personal information or profile from one smart card to another one replacing it (due to faulty card interface). There are three reasons for not supporting the “chaining” mechanism: -

Confidential

Page 22 of 22

6.1.1.8.1 6.1.1.8.2 6.1.1.8.3

Such a mechanism implies the STB has the capability to locally write something to the card, which is a security risk. The Nagravision System is designed to avoid smart card replacement, by allowing the smart card to be upgraded over the air. The Nagravision System is in place since 1995 and no smart card has been replaced due to security reason. The same subscriber experience can be achieved with other mechanisms at the head-end. If a smart card is faulty and must be replaced. It is very likely that it would not be readable by any chaining mechanism.

6.1.1.9 Must be able to re-route any unsubscribed channel or service to a default preview channel, or any pre-defined channel. The Nagravision Conditional Access Kernel (CAK), running on the STB, is able to tell the STB application this channel cannot be accessed. It then up to the application to tune to a designed channel. Such a channel designation may be added to the SI stream generated by the Nagravision Information Management System (IMS). 6.1.1.10 Must be able to interface with the Digital Set Top Boxes and be able to pre-programme channel maps and channel numbers. The channel map will be specific to the DVB-T offering and broadcasted to the STB using DVB-SI (NIT). Specific channel number information can be added to the SI stream as well.
