This document describes Real-time Transport Protocol (RTP) payload
formats for carrying each of MPEG-4 Audio and MPEG-4 Visual
bitstreams without using MPEG-4 Systems.  This document obsoletes RFC
3016.  It contains a summary of changes from RFC 3016 and discusses
backward compatibility to RFC 3016.  It is a necessary revision of
RFC 3016 in order to correct misalignments with the 3GPP Packet-
switched Streaming Service (PSS) specification regarding the RTP
payload format for MPEG-4 Audio.

For the purpose of directly mapping MPEG-4 Audio/Visual bitstreams
onto RTP packets, this document provides specifications for the use
of RTP header fields and also specifies fragmentation rules.  It also
provides specifications for Media Type registration and the use of
the Session Description Protocol (SDP).  The audio payload format
described in this document has some limitations related to the
signaling of audio codec parameters for the required multiplexing
format.  Therefore, new system designs should utilize RFC 3640, which
does not have these restrictions.  Nevertheless, this revision of RFC
3016 is provided to update and complete the specification and to
enable interoperable implementations.  [STANDARDS-TRACK]
