From: The IESG To: IETF-Announce Message-Id: Date: Mon, 02 Oct 2006 16:59:52 -0400 Subject: Protocol Action: 'RTP Payload Format and File Storage Format for the Adaptive Multi-Rate (AMR) and Adaptive Multi-Rate Wideband (AMR-WB) Audio Codecs' to Proposed Standard The IESG has approved the following document: - 'RTP Payload Format and File Storage Format for the Adaptive Multi-Rate (AMR) and Adaptive Multi-Rate Wideband (AMR-WB) Audio Codecs ' 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-rtp-amr-bis-06.txt * Technical Summary This document specifies a real-time transport protocol (RTP) payload format to be used for Adaptive Multi-Rate (AMR) and Adaptive Multi-Rate Wideband (AMR-WB) encoded speech signals. The payload format is designed to be able to interoperate with existing AMR and AMR-WB transport formats on non-IP networks. In addition, a file format is specified for transport of AMR and AMR-WB speech data in storage mode applications such as email. Two separate media type registrations are included, one for AMR and one for AMR-WB, specifying use of both the RTP payload format and the storage format. This document obsoletes RFC 3267. * Working Group Summary This is an update to RFC 3267, to properly define offer/answer behavior and to clarify various other details in light of implementation experience. It was not controversial. * Protocol Quality This is an update to a very widely implemented RTP payload format, incorporating a series of clarifications in the light of implementation experience. The media type review occurred in July 2006, with no objections. Harikishan Desineni provided working group last call comments.
