| Abstract
|
This memo describes a profile 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.
The 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. However, the encoding definitions are
independent of the particular transport mechanism used. 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.
