The Joint Collaborative Team on Video Coding is a group of video coding experts from ITU-T Study Group 16 (VCEG) and ISO/IEC JTC 1/-SC 29-/-WG 11 (MPEG) created to develop a new generation video coding standard that will further reduce by 50% the data rate needed for high quality video coding, as compared to the current state-of-the-art AVC standard (ITU-T H.264 | ISO/IEC 14496-10).

ITU-T Rec. H.264 | ISO/IEC 14496-10, commonly referred to as H.264/MPEG-4-AVC, H.264/AVC, or MPEG-4 Part 10 AVC has been developed as a joint activity within the JVT.
