From: The IESG To: IETF-Announce Message-Id: <20090518132611.9D7C73A7036@core3.amsl.com> Date: Mon, 18 May 2009 06:26:11 -0700 (PDT) Cc: Internet Architecture Board , avt mailing list , avt chair , RFC Editor Subject: [AVT] Protocol Action: 'RTP Payload Format for the Speex Codec' to Proposed Standard The IESG has approved the following document: - 'RTP Payload Format for the Speex Codec ' 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-rtp-speex-07.txt Technical Summary Speex is an open-source voice codec suitable for use in Voice over IP (VoIP) type applications. This document describes the payload format for Speex generated bit streams within an RTP packet. Also included here are the necessary details for the use of Speex with the Session Description Protocol (SDP). Working Group Summary The initial version of this draft was submitted in February 2002, and was eventually adopted as a working group draft in October 2005. After several false starts and changes in authorship, interest and progress picked up in 2007, leading to the completion of the draft. Adoption of the draft by the working group was delayed due to confusion on which signalling mechanisms should be defined. More recently, discussion has focussed on the detailed use of RTP headers, and media type parameter. The resulting format is a straight-forward RTP payload type specification. Document Quality There are several existing implementations (e.g. Ekiga, gstreamer). A Media type review was conducted starting on 31 March 2008; no issues were raised. Personnel Colin Perkins is the document shepherd. Cullen Jennings is the responsible area director.
