From: The IESG To: IETF-Announce Message-Id: <20090528181013.886073A6DC7@core3.amsl.com> Date: Thu, 28 May 2009 11:10:13 -0700 (PDT) Cc: Internet Architecture Board , avt mailing list , avt chair , RFC Editor Subject: [AVT] Protocol Action: 'RTP Payload Format for ITU-T Recommendation G.722.1' to Proposed Standard The IESG has approved the following document: - 'RTP Payload Format for ITU-T Recommendation G.722.1 ' as a Proposed Standard This document is the product of the Audio/Video Transport Working Group. The IESG contact persons are Cullen Jennings and Robert Sparks. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-avt-rfc3047-bis-09.txt Technical Summary International Telecommunication Union (ITU-T) Recommendation G.722.1 is a wide-band audio codec. This document describes the payload format for including G.722.1 generated bit streams within an RTP packet. The document also describes the syntax and semantics of the SDP parameters needed to support G.722.1 audio codec. Working Group Summary The G722.1 codec can change bit rate in mid-stream. Dealing with this successfully was an issue for discussion during WGLC. The resolution was to require each bit rate to have its own payload type. Document Quality Magnus Westerlund performed the initial review of the document. Aurelien Sollaud also provided careful reviews, particularly during WGLC. Personnel Tom Taylor is the Document Shepherd. RFC Editor Note In section 7 OLD The new draft obsoletes RFC3047 NEW This specification obsoletes RFC3047
