Abstract

   The Motion Picture Experts Group (MPEG) Committee (ISO/IEC JTC1/SC29
   WG11) is a working group in ISO that produced the MPEG-4 standard.
   MPEG defines tools to compress content such as audio-visual
   information into elementary streams.  This specification defines a
   simple, but generic RTP payload format for transport of any non-
   multiplexed MPEG-4 elementary stream.
