Description of 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).
