#MPEGFuture is proposing that MPEG become a JTC 1 Subcommittee. To analyse the benefits of this new setting, I have already posted hashtag#MPEGGovernance and hashtag#MPEGproductivity and this is the time for hashtag#MPEGCollaboration. Today systems become more and more complex and include more and more features. Sometime ago a TV set was, well, a TV set. Today it has many more things. A handset is an incredible integrator of technologies: collaboration between standards groups is imperative. In 1992 MPEG started a successful collaboration with ITU-T SG 16 to jointly develop standards for MPEG-2 video coding and transport. This collaboration has continued producing two more successful standards: Advanced Video Coding (AVC) and High Efficiency Video Coding (HEVC). Versatile Video Coding (VVC) is close to reaching FDIS stage and will bring to 5 the successful collaborations. In the Mid 2000s MPEG started a collaboration with 3GPP on 2 major standards (ISOBMFF & DASH). In 2013 it started the devlopment of Mixed and Augmented Reality Reference Model with JTC 1/SC 24. In 2016 MPEG started the development of the DNA read compression startdard with ISO TC 276 Biotechnology: 3 standards have been produced (MPEG-G Part 1, 2 & 3) and 3 standards are under development (MPEG-G parts 4, 5 & 6).
