Abstract

   This document describes a payload type for bundled, MPEG-2 encoded
   video and audio data that may be used with RTP, version 2. Bundling
   has some advantages for this payload type particularly when it is
   used for video-on-demand applications. This payload type may be used
   when its advantages are important enough to sacrifice the modularity
   of having separate audio and video streams.

1. Introduction

   This document describes a bundled packetization scheme for MPEG-2
   encoded audio and video streams using the Real-time Transport
   Protocol (RTP), version 2 [1].

   The MPEG-2 International standard consists of three layers: audio,
   video and systems [2]. The audio and the video layers define the
   syntax and semantics of the corresponding "elementary streams." The
   systems layer supports synchronization and interleaving of multiple
   compressed streams, buffer initialization and management, and time
   identification.  RFC 2250 [3] describes packetization techniques to
   transport individual audio and video elementary streams as well as
   the transport stream, which is defined at the system layer, using the
   RTP.
