JTC1SC29WG11

JTC1SC29WG11 stands for ISO/IEC JTC1 Subcommittee 29 Working Group 11, a formal working group within ISO/IEC JTC1/SC29. SC29 covers coding of audio, picture and multimedia information, and WG11 is the MPEG-focused group responsible for developing and maintaining video coding standards. The group brings together experts from national bodies and industry to standardize methods for compressing and representing moving pictures and related multimedia data, with coordination across international contexts.

The primary mandate of JTC1SC29WG11 is to advance video compression technologies and their interoperable implementation. Its work encompasses the creation, review, and maintenance of MPEG standards, including but not limited to MPEG-1, MPEG-2, and the MPEG-4 Visual specifications, as well as subsequent video coding standards associated with the MPEG family. The group develops conformance provisions, profiles and levels, and reference software or test data to support interoperability and compliance testing across devices and software.

WG11 operates in close collaboration with other entities inside SC29, and maintains liaison with external standards bodies such as ITU-T to align on joint activities related to video coding. Outputs of the group typically take the form of International Standards (IS) and Technical Reports (TR) within the ISO/IEC framework, guiding the global adoption of standardized video codecs and related technologies across broadcasting, streaming, storage, and multimedia applications.

Overall, JTC1SC29WG11 plays a central role in the ongoing evolution and harmonization of MPEG video standards, influencing how digital video is encoded, transmitted, and rendered worldwide.
