Technical Summary

This memo describes an RTP payload format for Scalable Video Coding
  (SVC) as defined in Annex G of ITU-T Recommendation H.264, which is
technically identical to Amendment 3 of ISO/IEC International Standard
14496-10.  The RTP payload format allows for packetization of one or more
Network Abstraction Layer (NAL) units in each RTP  packet payload, as well
as fragmentation of a NAL unit in multiple  RTP packets.  Furthermore, it
supports transmission of an SVC stream
  over a single as well as multiple RTP sessions.  The payload format
  defines a new media subtype name "H264-SVC", but is still backwards
  compatible to [I-D.ietf-avt-rtp-rfc3984bis] since the base layer,
  when encapsulated in its own RTP stream, must use the H.264 media
  subtype name ("H264") and the packetization method specified in [I-
  D.ietf-avt-rtp-rfc3984bis].  The payload format has wide
  applicability in videoconferencing, Internet video streaming, and
  high bit-rate entertainment-quality video, among others.

Working Group Summary

There was a very heated discussion before the two proposals were merged.
Once agreement was achieved the work progress smoothly using a design team.

The registration template was posted to for 2 weeks review:

Document Quality

This is a payload specification for H.264 scalable video coding. It is being
used in some streaming and video conferencing applications. It is referenced
by other standard bodies.
