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.

This document is a product of the Audio/Video Transport Working Group
of the IETF.

This is now a Draft Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.
