Demultiplexing and decoding an MPEG2 Transport Stream (MPEG2-TS)
requires the knowledge of specific information about the transport
stream, which we refer to as the MPEG2-TS Preamble.  While this
information is spread over different locations throughout the
transport stream and can be eventually assembled after some time a
receiver started receiving the MPEG2-TS, the time it takes to
retrieve all this information (especially in multicast environments)
may be long.  Instead, having this information readily available as a
Preamble and sending the Preamble to a receiver that will shortly
start receiving the transport stream will virtually eliminate the
waiting time and let the receiver start processing/decoding the
MPEG2-TS sooner.  In this document, we give an overview of the
MPEG2-TS and the delay components in video systems, and motivate the
need for constructing and using the MPEG2-TS Preamble for rapidly
acquiring the source stream in RTP multicast sessions.  We also
define and register the RTP payload format for the MPEG2-TS Preamble.
