Schmidt, R. Sperschneider Status: Standards Track Date: October 2009 Mailbox: frans.de.bont@philips.com, stefan.doehla@iis.fraunhofer.de, malte.schmidt@dolby.com, ralph.sperschneider@iis.fraunhofer.de Pages: 12 Characters: 26189 Updates: RFC3640 I-D Tag: draft-ietf-avt-rtp-mps-03.txt URL: http://www.rfc-editor.org/rfc/rfc5691.txt This memo describes extensions for the RTP payload format defined in RFC 3640 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 that doesn't use 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.
