In its meeting of March 11-15, 2002 in Jeju, Korea, WG11 (MPEG)
reviewed the situation with respect to the status of the companion
internet drafts for transport of MPEG-4 content over IP,
draft-ietf-avt-mpeg4-multisl-04.txt and
draft-ietf-avt-mpeg4-simple.01.txt, respectively. MPEG concluded that:

1) there is a clear market need for a general RTP payload format for
   carriage of MPEG-4 content;
2) there is substantial procedural risk on promotion of two companion
   internet drafts to RFC;
3) there is an urgent market need to promote
   draft-ietf-avt-mpeg4-simple.01.txt to RFC, which has a clearly higher
   priority than promotion of draft-ietf-avt-mpeg4-multisl-04.txt to RFC;
4) there is desire in MPEG to consider requirements beyond
   draft-ietf-avt-mpeg4-simple.01.txt, both from the current MPEG-4
   perspective and on carriage of future MPEG-4 streams, in particular
   MPEG-4 part 10 video, often also referred to as AVC-video or H.26L.

To anticipate on the above situation and to minimise the risk for
promotion to RFC of draft-ietf-avt- mpeg4-simple.01.txt, MPEG suggests
to decouple both companion drafts and to make draft-ietf-avt-
mpeg4-simple.01.txt a stand-alone document. Furthermore, MPEG proposes
to continue its joint effort with IETF on
draft-ietf-avt-mpeg4-multisl-04.txt with the objective of positioning
it as a super-set (extension) of draft-ietf-avt-mpeg4-simple.01.txt.
