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 email@example.com for 2 weeks review: <http://www.ietf.org/mail-archive/web/ietf-types/current/msg00996.html> 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. Personnel Who is the Document Shepherd for this document?
