conjunction with ISO/IEC’s Joint Picture Experts Group (JPEG), ITU-T’s Study Group 16
hosted a workshop
on Video and Image Coding and Applications (VICA) at ITU headquarters in
Geneva, 22 to 23 July.
Key experts joined users to review the development, assessment and application
of video and image coding and to discuss and start work on an action plan and a
roadmap for VICA standardization.
Introducing the workshop, Houlin Zhao, director of TSB, emphasized the
importance of video and image compression not only from a telecommunication
perspective, but also for consumers. He highlighted ITU-T’s extensive and
constructive partnerships with both MPEG, and ISO/IEC’s Joint Photographic
Experts Group (JPEG), which have achieved practical and innovative results. He
also highlighted the importance of the work from universities in the field.
The workshop introduced topics including the history and challenges of video
and image compression up to the development of ITU-T Recommendation H.264, and
of the JPEG-2000 family of standards. It looked at how these standards will be
applied to current and future technologies surrounding television, computers,
videoconferencing, home networking and mobile phones, and how VICA standards
are affected by the evolution of multimedia services and applications.
Presentations also stimulated discussion on how standards work in the field,
including how next generation networks (NGN) can support the development of
so-called ubiquitous networks – any device, anytime, anywhere. Current work on
home network environments was also taken into account.
Following the event, Study Group 16 met from 26 July to 5 August and further
discussed the results of the workshop in order to continue to develop standards
that will improve the quality of service and ubiquity of telecommunication
technologies and facilitate the global dissemination of multimedia content.
