A concept of …

What is a Digital Media ƒ The form and technology used to communicate digital information; ƒ Examples: ƒ Text … … ASCII Code, JIS Code, EUC ƒ Graphics … BMP, PNG, GIF, TIFF, JPEG (2D & 3D) Open GL, VRML ƒ Sound …… MIDI, MP3, WMA ƒ Video … …. RMV, MPEG,WMV ƒ Animation … GIF Animation, Flash, 3-D Animation, Virtual Reality 6

A concept of …

What is a Digital Multimedia ƒ The use of computers to present text, graphics, sound, video, and animation in an integrated way ƒ Any combination of two or more media, represented in digital form, sufficiently integrated to be presented via a single interface, or manipulated by a single computer program. 7

What is a multimedia system? ƒ A multimedia system supports the integrated

storage, transmission and representation of the discrete media types text, graphics and image and the continuous media types audio and video on a digital computer. ƒ Examples: ƒ ƒ ƒ

MS-PowerPoint ….multimedia presentation WebCT …. Web-based multimedia e-learning i-Tunes and YouTube web system…..Multimedia storage and transmission (Multimedia Management System), etc 8

Time-Independent and Time-Dependent Media Time-Independent Media ƒ Information is not related to the timing of the data stream ƒ All „classic“ media in the computer, such as: ƒ text ƒ graphics (line drawings, vector graphic) ƒ image (photo, pixel graphics).

Time-Dependent Media ƒ Information is time-related, must be shown to the user at specific points in time ƒ Continuous data streams ƒ Data appears in regular intervals ƒ Examples: ƒ ƒ ƒ ƒ

Audio (continuous) Video (continuous) An animation (not a continuous stream, but time-dependent) An interactive game on the Internet (not a continuous stream, but has real-time requirements) 9

Definition of a Multimedia System ƒ A multimedia system is characterized by the integrated ƒ ƒ ƒ ƒ ƒ

production, processing, storage, transmission and representation

of several time-dependent and time independent media streams.

Network Requirements of Different Types of Data Streams

12

Goals of Compression

The compression of multimedia data streams saves ƒ storage space ƒ transmission bandwidth 13

Multimedia Courses in CAP-ICT Curriculum (A Multimedia Track) ƒ The Multimedia related courses: ƒ ƒ ƒ ƒ ƒ ƒ

Design Usability………… Design Fundamental Multimedia Design Technologies …multimedia contents design Design in Digital Age ……multimedia storage and transmission CAD/CAM ………………..3 Dimensional (3D) Modeling Computer Graphics………3D programming Multimedia applications … Case study of multimedia applications

ƒ The courses introduce students to basic understanding on ƒ ƒ ƒ

multimedia design technology. Students will be introduced to Multimedia tools and trained in actual multimedia contents design and programming. The courses will provide students with basic skills and various aspects and issues of the area of the multimedia design technology. The class will mostly be lectures, practical trainings and projects. 14

Basic Understanding on Multimedia Technologies Contents:

ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ

Introduction to Multimedia, Enabling Technologies, Graphics; Vector graphics and Bitmapped graphics, Image processing, File Formats, Color Science, Digitizing Sound and Video, Hypertext and Hypermedia, Multimedia programming, Multimedia and Networks, etc 15

Digital Media Tools Available tools in the classroom and Multimedia Lab:

ƒ ƒ ƒ ƒ ƒ

Photoshop ……for manipulating bitmapped images Illustrator ……. for manipulating vector graphics Flash ………… for animation and interactivity Premiere ……. for video and sound Dreamweaver…for multimedia web development , etc

16

Area of Research ƒ Multimedia Contents Development, ƒ Contents Management System, ƒ Multimedia Applications, ƒ Modeling and Visualization ƒ Data Processing, Compressing and Transmission, etc.

17

Conclusion ƒ Modern multimedia systems are all-digital. ƒ We define multimedia as the integrated production, processing, storage, transmission and representation of several time-dependent and time-independent media streams. ƒ There are some Multimedia related courses in the APU-ICT curriculum (Multimedia Track) ƒ Digital media tools are available to be used in APU multimedia lab (CAMAS) and IPS-9

18

Multimedia Design Technologies (A course overview) ƒ Recommended qualifications / knowledge ƒ Introduction to programming and Internet Fundamentals courses have been successfully completed with passing grades

ƒ Teaching Methods : ƒ ƒ ƒ ƒ

Lectures (hardcopy handouts, Power Point, Video) Practical training of multimedia contents design Projects (individually or in group) Reports submission & Quizzes

ƒ (The course will be conducted through lectures and practical training will be provided according to the textbook. Reports will be assigned as the course proceeds. Teaching assistants will be arranged to facilitate individual guidance during the practical training. )

19

Method of Grade Evaluation ƒ The final grade (100%) will be awarded using the following criteria of evaluation: ・Attendance …………………… 20 % ・Quizzes…………………………20 % ・Exercises/assignments ……… 20% ・Mid-term Project………………. 15 % ・End of Term Project……………25 %
