Abstract
This document describes a profile called "RTP/AVP" for the use of the
real-time transport protocol (RTP), version 2, and the associated
control protocol, RTCP, within audio and video multiparticipant
conferences with minimal control. It provides interpretations of
generic fields within the RTP specification suitable for audio and
video conferences. In particular, this document defines a set of
default mappings from payload type numbers to encodings.
This document also describes how audio and video data may be carried
within RTP. It defines a set of standard encodings and their names
when used within RTP. The descriptions provide pointers to reference
implementations and the detailed standards. This document is meant
as an aid for implementors of audio, video and other real-time
multimedia applications.
This memorandum obsoletes RFC 1890. It is mostly backwards-
compatible except for functions removed because two interoperable
implementations were not found. The additions to RFC 1890 codify
existing practice in the use of payload formats under this profile
and include new payload formats defined since RFC 1890 was published.
