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.
