Technical Summary This memo describes extensions for the RTP payload format defined in RFC3640 for the transport of MPEG Surround multi-channel audio. Additional Media Type parameters are defined to signal backwards compatible transmission inside an MPEG-4 audio elementary stream. In addition a layered transmission scheme without using the MPEG-4 systems framework is presented to transport an MPEG Surround elementary stream via RTP in parallel with an RTP stream containing the downmixed audio data. Working Group Summary There were no objections to making this a WG item, and limited comments during WGLC. Document Quality Colin Perkins was the primary reviewer during Working Group Last Call. The proposed parameters were presented for Media Type review in a message dated 19/11/2008. DVB, ATSC, and 3GPP have dependencies on this document. Personnel The PROTO Document Shepherd is Tom Taylor.
