Charter for Working Group
The Real-time Transport Protocol (RTP) 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 broad range of applications, from telephony to
television over IP. RTP itself is now an Internet Standard. Its
associated profiles, extensions, and payload formats are currently at
various levels of standards maturity. As new applications emerge, there
is a need for guidelines for the use of the RTP/RTCP protocols and
extensions specific to those applications.
The AVTCORE working group is chartered for the following tasks:
1. To maintain the core RTP/RTCP specifications and the AVP, SAVP, AVPF,
and SAVPF profiles. The group will provide architectural guidance for
extending the protocols and guidelines for their proper use.
2. 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.
3. To specify and maintain payload formats for use with RTP. The working
group will develop RTP payload formats for new media codecs, review and
revise existing payload formats to advance those that are especially
useful to Internet Standard, and declare others Historic. The group will
follow the guidelines established in "Guidelines for Writers of RTP
Payload Format Specifications" [BCP 36] and "How to Write an RTP Payload
Format" (RFC 8088), and is responsible for maintaining those guidelines.
4. To evaluate and process proposals for RTP eXtended Report Block
(XRBLOCK) definitions containing new metrics. The group will work within
the framework defined by RFC 3611, "RTP Control Protocol Extended Reports
(RTCP XR)" along with other RTP monitoring architecture being developed
in the working group. It will follow the guidelines established in RFC
5968, "Guidelines for Extending the RTP Control Protocol (RTCP)" and RFC
6390, "Guidelines for Considering New Performance Metric Development".
The AVTCORE working group will coordinate closely with the Security Area
while working on maintenance and enhancements to the SRTP Profile (SAVP).
