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
