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.
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]

Together with JPEG, MPEG is organized under ISO/IEC JTC 1/SC 29 – Coding of audio, picture, multimedia and hypermedia information.
MPEG-4 is a group of international standards for the compression of digital audio and visual data, multimedia systems, and file storage formats. It was originally introduced in late 1998 as a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) under the formal standard ISO/IEC 14496 – Coding of audio-visual objects. Uses of MPEG-4 include compression of audiovisual data for Internet video and CD distribution, voice and broadcast television applications. The MPEG-4 standard was developed by a group led by Touradj Ebrahimi and Fernando Pereira.
MPEG-1 Audio Layer II or MPEG-2 Audio Layer II is a lossy audio compression format defined by ISO/IEC 11172-3 alongside MPEG-1 Audio Layer I and MPEG-1 Audio Layer III (MP3). While MP3 is much more popular for PC and Internet applications, MP2 remains a dominant standard for audio broadcasting.
