ITU-T Systems and Video Experts,
I am at an MPEG meeting in France. There has been a lot of recent discussion here and in the IETF on how to carry MPEG-4 data on IP networks. I was asked by some MPEG participants to help explain and understand the impact of this work on ITU-T SG16.
My understanding is that the H.323 community has been expecting an IETF RFC with Proposed Standard status to be approved prior to the November SG16 meeting sufficient to specify an RTP packetization format for use in H.323 systems to carry MPEG-4 video (and perhaps audio) elementary streams.
However, there are some discussions here at MPEG about how to ensure that any such specification is adequate not only for the needs of H.323 but also for MPEG-4 systems as well.
As a result, it appears that MPEG is poised to recommend tomorrow that the current Kikuchi-san Internet Draft not be promoted to Proposed Standard RFC status in the IETF. This seems to mean that we are unlikely to be able to reach Decision status for this feature in H.323 in November in SG16.
The SG16 community needs to understand this unfortunate situation and its impact on the progress of work for the SG 16 meeting in November.
Best Wishes,
Gary Sullivan
