ISO/IEC JTC 1/SC 29, entitled Coding of audio, picture, multimedia and hypermedia information, is a standardization subcommittee of the Joint Technical Committee ISO/IEC JTC 1 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It develops and facilitates international standards, technical reports, and technical specifications within the field of audio, picture, multimedia, and hypermedia information coding. The standards developed by SC 29 have been recognized by nine Emmy Awards.

The international secretariat of SC 29 is the Japanese Industrial Standards Committee (JISC) of Japan.[1]

History

ISO/IEC JTC 1/SC 29 was established in 1991, when the subcommittee took over the tasks of ISO/IEC JTC 1/SC 2/WG 8. Its title, "Coded representation of audio, picture, multimedia and hypermedia information", has not been changed since its inception. Within its first year, SC 29 established four working groups, a secretariat, and working group conveners, and held its first plenary in Tokyo, Japan. Its founding chair was Hiroshi Yasuda of NTT, who continued to serve in that capacity through 1999. Subsequent chairs have been Hiroshi Watanabe of NTT (2000–2006),[2] Kohtaro Asai of Mitsubishi Electric (2007–2017),[3] Teruhiko Suzuki of Sony (2018–2020),[4] and Gary Sullivan of Microsoft (2021–present).[5][6]

ISO/IEC JTC 1/SC 29 has published 599 standards, including standards for JPEG (ISO/IEC 10918-1), JPEG-2000 (ISO/IEC 15444-1), MPEG-1 (ISO/IEC 11172-1), MPEG-2 (ISO/IEC 13818), MPEG-4 (ISO/IEC 14996), MPEG-4 AVC (ISO/IEC 14496-10), JBIG (ISO/IEC 11544), and MHEG-5 (ISO/IEC 13522-5).[7]

Emmy Award recognitions

ISO/IEC JTC 1/SC 29 has received nine Emmy Awards in recognition of the standards it has developed.

Scope

The scope of ISO/IEC JTC 1/SC 29 includes the development of standards for "efficient coding of digital representations of images, audio and moving pictures" and other digital information, along with supporting media systems and associated quality of experience and performance metrics.[21]

Structure

ISO/IEC JTC 1/SC 29 has eight active working groups (WGs), each of which carries out specific tasks in standards development within scope of the subcommittee.[22] It also contains five advisory groups (AG) for coordination and to provide expertise on particular subjects. Working groups and advisory groups can be created or disbanded by decisions of the subcommittee and are ordinarily chartered for renewable three-year terms. The focus of each working group is described in the group's terms of reference. The active advisory groups and working groups of SC 29 are:[23]
