              RTP Payload Format for Scalable Video Coding

Abstract

   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 backward
   compatible to RFC 6184 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 RFC 6184.  The payload format
   has wide applicability in videoconferencing, Internet video
   streaming, and high-bitrate entertainment-quality video, among
   others.
