The IESG has approved the following document: - 'Enhancements to RTP Payload Formats for EVRC Family Codecs ' <draft-ietf-avt-compact-bundled-evrc-11.txt> as a Proposed Standard This document is the product of the Audio/Video Transport Working Group. The IESG contact persons are Cullen Jennings and Jon Peterson. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-avt-compact-bundled-evrc-11.txt * Technical Summary This document updates the EVRC RTP payload formats defined in RFC 3558 with several enhancements and extensions. In particular, it defines support for the header-free and interleaved/bundled packet formats for the EVRC-B codec, a new compact bundled format for the EVRC and EVRC-B codecs, as well as discontinuous transmission (DTX) support for EVRC and EVRC-B encoded speech transported via RTP. VoIP applications operating over low bandwidth dial-up and wireless networks require such enhancements for efficient use of the bandwidth. * Working Group Summary A straight-forward RTP Payload Format, to address a new version of the codec. Only unusual feature is the tight specification of the DTX parameters, rather than relying on end-point discretion (as is the norm). * Protocol Quality This drafts was reviewed on the ietf-types list in May 2006; there were no objections. Adam Li provided working group last call comments on DTX operation. Colin Perkins did the PROTO write-up. David Black did Gen ART Review. _______________________________________________ IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
