ISO/IEC JTC 1/SC 29 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), that develops and facilitates international standards, technical reports, and technical specifications within the field of audio, picture, multimedia, and hypermedia information coding. The international secretariat of ISO/IEC JTC 1/SC 29 is the Japanese Industrial Standards Committee (JISC) located in 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 original title was “Coded Representation of Audio, Picture, Multimedia and Hypermedia Information.” Within its first year, ISO/IEC JTC 1/SC 29 established four working groups, appointed its chairperson, secretariat, and working group conveners, and held its first plenary in Tokyo, Japan. ISO/IEC JTC 1/SC 29 has published 475 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 14996-1), MPEG-4 AVC (ISO/IEC 14496-10), JBIG (ISO/IEC 11544), and MHEG-5 (ISO/IEC 13522-5).[2] In 1996, when the JPEG, MPEG-1, and MPEG-2 standards became widely recognized for their technological advancements, ISO/IEC JTC 1/SC 29 was awarded the 1995-1996 Technology and Engineering Emmy Award for Outstanding Achievement in Technical/Engineering Development.[3][4][5]:11 The MPEG-4 AVC standard also won two Emmys: The Primetime Emmy Engineering Award in September 2008, and the 2007-2008 Technology and Engineering Award in January 2009.[5]:20[6][7][8][9][10]

Scope

The scope of ISO/IEC JTC 1/SC 29 is “Standardization of coded representation of audio, picture, multimedia and hypermedia information – and sets of compression and control functions for use with such information – such as:”[11]

Structure

ISO/IEC JTC 1/SC 29 is made up of two active working groups (WGs), each of which carries out specific tasks in standards development within the field of audio, picture, multimedia, and hypermedia information coding. Working groups can be disbanded if the group’s working area is no longer applicable to standardization needs, or established if new working areas arise. The focus of each working group is described in the group’s terms of reference. Active working groups of ISO/IEC JTC 1/SC 29 are:[12]

  • Audio information
  • Bi-level and Limited Bits-per-pixel Still Pictures
  • Digital Continuous-tone Still Pictures
  • Computer Graphic Images
  • Moving Pictures and Associated Audio
  • Multimedia and Hypermedia Information for Real-time Final Form InterchangeISO/IEC JTC 1/SC 29 is made up of two active working groups (WGs), each of which carries out specific tasks in standards development within the field of audio, picture, multimedia, and hypermedia information coding.
