Title : Liaison Letter to IETF regarding JVT Video Packetization

ISO/IEC JTC 1/SC 29/WG 11 (MPEG) and ITU-T SG16 WP3 Q.6 (VCEG) agreed to form this Joint Video Team (JVT) to jointly develop a new video codec standard based initially on the draft H.26L model, for use in ISO/IEC systems, ITU-T systems, and for general use on IP networks via RTP.

MPEG believes that interoperability and simplicity will be greatly advanced if packetization of the JVT codec (also known as ‘H.26L’ and ‘MPEG-4 Part 10’), for use on IP networks via RTP, is defined by a single IETF RFC, to be referenced by both ISO/IEC and ITU-T systems. This will enable the JVT video data to be carried by all RTP-based systems in an interoperable way.

MPEG also requests that the IETF refrain from moving forward any work in IETF on this topic until a single common technique is agreed. We do not anticipate any great difficulties in reaching agreement, and plan that this work should be completed and submitted to IETF before the approval of the JVT codec standard (planned for approximately the end of 2002).

MPEG has formed an Ad-Hoc group to manage the development of the common Internet Draft on this subject. We request that liaison communications be addressed to this Ad-Hoc group to accomplish the goals described above.
