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. SC 29 includes the well-known JPEG and MPEG experts groups, and 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]

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 Dolby Labs (2021–present, originally from Microsoft before moving to Dolby in 2023).^[5][6]

In 2003, SC 29 was the inaugural recipient of the Lawrence D. Eicher Award, an award that has been given by ISO to only one technical committee or subcommittee each year, which "recognizes the significant contribution and superior performance of an ISO technical committee (TC) or subcommittee (SC) to the development of ISO International Standards".^[7][8]

As of January 2023, SC 29 is responsible for 610 currently published standards and updates of 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), MHEG-5 (ISO/IEC 13522-5), etc.^[9][10]

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

• In 1996, when the JPEG, MPEG-1, and MPEG-2 standards became widely recognized for their technological advancements, SC 29 was awarded a 1995–1996 Technology and Engineering Emmy Award for Outstanding Achievement in Technical/Engineering Development.^{[11][12][13]: 11}
• The MPEG-4 AVC video coding standard also won two Emmys:^{[13]: 20 [14][15][16][17][18]}
  • The Primetime Emmy Engineering Award in September 2008 for the High Profile of the standard
  • The Technology and Engineering Emmy Award in January 2009 (for the standard as a whole)
• The MPEG-2 transport stream format was recognized by a Technology and Engineering Emmy Award in 2014.^[19]
• The High Efficiency Video Coding (HEVC) standard was recognized by a Primetime Emmy Engineering Award in 2017.^[20]
• The JPEG standard was recognized by a Primetime Emmy Engineering Award in 2019.^[21]
• The ISO Base Media File Format (ISOBMFF) standard was recognized by a Technology and Engineering Emmy Award in 2021.^[22]
• Two Technology and Engineering Emmy Awards were received in 2022:^[23][5][6]
  • The MPEG-DASH video streaming protocol
  • The Open Font Format standard

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.^[9]

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.^[24] 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:^[9]
