EUSIPCO '98 Conference

TUTORIAL - A

MULTIMEDIA AUDIOVISUAL

COMMUNICATION SERVICES

Low bit rate audio visual communication services aimed at mobile (cellular) channels, multimedia videoconferencing on a PC via ordinary telephone lines, and videophones. Video over the internet, video e-mail. Object/content based coding. Synthetic & natural (hybrid) video/audio coding. Animation, graphics, video composition etc.

1. IS G.723.1 Dual rate speech coder for multimedia telecommunication transmitting at 5.3 and 6.3 Kbits/s. Also annexes.

2. MPEG-4 Video/Audio Coding ISO/IEC JTC1/SC29/WG11, Requirements, Test/Evaluation, Call for proposals, Verification Models, (VM) system description language (MSDL) (IS: Nov. 1998). VM 9.0 (Oct. 1997), Synthetic and natural images hybrid coding (SNHC). Audio coding. (Oct. 1997). Audio WD V 5.0. Systems,Content/object based coding, functionalities and applications.

3. Very low bit rate audiovisual communication services, H.263 IS by ITU-T study Group 15. H. 263 is part of H.324 which includes multiplexing protocols, multimedia system control, terminals, dialing etc., IS: International Standard H. 263 + Near term standardization of enhancements of the H. 263 video coding algorithm for real-time telecommunication. IS: April 1997. H. 263 L (Long term) LBR video coding recommendation achieving better video quality, lower complexity and better error resilience. ITU-T low bit-rate experts groups advanced video coding project aimed at real-time audio/visual conversational services/ applications. IS to coincide with MPEG-4. Draft Rec. H.223/Annex A: Multiplexing protocol for low bit-rate multimedia communication.

4. MPEG-2 Multiview profile (stereoscopic video coding), 4:2:2 profile and adaptive audio coder (nonbackward compatible audio) (AAC)

5. JPEG Extensions, JPEG-2000

6. MPEG-7: Multimedia content driven interface.

INTENDED AUDIENCE:

This course is directed at researchers, engineers, technical managers and academia who like to keep abreast with the emerging/established standards aimed at interactive video/audio communications/storage services at very low bit rates so that software/hardware at various levels can be designed/developed. They can also integrate the boards/codecs with their existing PCs/workstations resulting in multimedia, teleconferencing, videophone and other interactive services.

SPEAKER:

Dr. K. R. Rao has conducted the short course/workshop/tutorial in this field worldwide for Universities, Research Institutes and Industries. He is co-author of the book "Techniques and standards for image, video and audio coding" Prentice Hall (1996). This book is now translated into Japanese.
