Abstract

   This memo describes a packetization scheme for MPEG video and audio
   streams.  The scheme proposed can be used to transport such a video
   or audio flow over the transport protocols supported by RTP.  Two
   approaches are described. The first is designed to support maximum
   interoperability with MPEG System environments.  The second is
   designed to provide maximum compatibility with other RTP-encapsulated
   media streams and future conference control work of the IETF.

   This memo is a revision of RFC 2038, an Internet standards track
   protocol.  In this revision, the packet loss resilience mechanisms in
   Section 3.4 were extended to include additional picture header
   information required for MPEG2.  A new section on security
   considerations for this payload type is added.
