Audio/Video Transport Extensions (AVTEXT) --------------------------------------------------- Current Status: Active Working Group Chairs: * Keith Drage * Magnus Westerlund Real-time Applications and Infrastructure Area Director(s): * Gonzalo Camarillo * Robert Sparks Real-time Applications and Infrastructure Area Advisor: * Gonzalo Camarillo Mailing Lists: General Discussion: avtext@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/avtext Archive: http://www.ietf.org/mail-archive/web/avtext/index.html Description of Working Group: The Full-Standard Real-time Transport Protocol, RTP [RFC 3550], along with its associated profiles and payload formats provides for real- time transmission of audio and video over unicast and multicast transports. RTP is widely implemented, and deployed for a wide range of applications, ranging from telephony to television over IP. As new applications have emerged, the need for guidelines for the use of the RTP/RTCP protocols and extensions specific to those applications has been identified. The AVTEXT working group is charted to develop application-specific guidelines for the use of RTP/RTCP protocols with the AVP, SAVP, AVPF, and SAVPF profiles, and extensions to those protocols that are driven by application-specific needs. Proposals for extensions with general applicability to many different RTP/RTCP usages should be taken to the AVTCORE working group. The AVTEXT working group is constrained to use the protocol extension mechanisms defined in the core protocols (such as RTP Header extensions [RFC5285], AVPF Feedback Messages [RFC4585], and SDES Items [RFC3550]). If new ways to extend the core protocols are needed, they will be developed in the AVTCORE working group. In addition to the milestones called out below, the AVTEXT working group's initial tasks will include completing any new work identified during IESG evaluation for the Rapid Acquisition of Multicast RTP Sessions. Goals and Milestones: Jun 2011 Submit Considerations for RAMS Scenarios for Informational Oct 2011 Submit RTP Header extension for mixer to client audio level indication as Proposed Standard Oct 2011 Submit RTP Header extension for client to mixer audio level indication as proposed standard Dec 2011 Submit Support for multiple clock rates in an RTP session for Proposed Standard Dec 2011 Submit SRTP Store-and-Forward Use Cases and Requirements for Informational Dec 2011 Submit Use of the Secure Real-time Transport Protocol (SRTP) in Store-and-Forward Applications for Proposed Standard From keith.drage@alcatel-lucent.com Thu Jan 27 06:53:28 2011 Return-Path: X-Original-To: avtext@core3.amsl.com Delivered-To: avtext@core3.amsl.com Received: from localhost (localhost [127.0.0.1]) by core3.amsl.com (Postfix) with ESMTP id 2383B3A68C6; Thu, 27 Jan 2011 06:53:28 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -105.626 X-Spam-Level: X-Spam-Status: No, score=-105.626 tagged_above=-999 required=5 tests=[AWL=0.623, BAYES_00=-2.599, HELO_EQ_FR=0.35, RCVD_IN_DNSWL_MED=-4, USER_IN_WHITELIST=-100] Received: from mail.ietf.org ([64.170.98.32]) by localhost (core3.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id lbsBjI06fSZT; Thu, 27 Jan 2011 06:53:27 -0800 (PST) Received: from smail3.alcatel.fr (smail3.alcatel.fr [64.208.49.56]) by core3.amsl.com (Postfix) with ESMTP id 0FCF53A68C0; Thu, 27 Jan 2011 06:53:23 -0800 (PST) Received: from FRMRSSXCHHUB04.dc-m.alcatel-lucent.com (FRMRSSXCHHUB04.dc-m.alcatel-lucent.com [135.120.45.64]) by smail3.alcatel.fr (8.14.3/8.14.3/ICT) with ESMTP id p0REu3xa031355 (version=TLSv1/SSLv3 cipher=RC4-MD5 bits=128 verify=NOT); Thu, 27 Jan 2011 15:56:26 +0100 Received: from FRMRSSXCHMBSC3.dc-m.alcatel-lucent.com ([135.120.45.46]) by FRMRSSXCHHUB04.dc-m.alcatel-lucent.com ([135.120.45.64]) with mapi; Thu, 27 Jan 2011 15:56:21 +0100 From: "DRAGE, Keith (Keith)" To: IETF AVT WG , "avtext@ietf.org" Date: Thu, 27 Jan 2011 15:56:19 +0100 Thread-Topic: Call for adoption of text for audio level milestones Thread-Index: Acu+MlsFvM0YX6CeQySkhDVDbOUeWQ== Message-ID: Accept-Language: en-US Content-Language: en-US X-MS-Has-Attach: X-MS-TNEF-Correlator: acceptlanguage: en-US Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 X-Scanned-By: MIMEDefang 2.64 on 155.132.188.83 Subject: [avtext] Call for adoption of text for audio level milestones X-BeenThere: avtext@ietf.org X-Mailman-Version: 2.1.9 Precedence: list List-Id: Audio/Video Transport Extensions working group discussion list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 27 Jan 2011 14:53:28 -0000 (As AVTEXT WG cochair) This message is copied to the AVTCORE list for those who are not yet on the= new list.
