Abstract

   This document describes an architecture for the transport of IP
   Datagrams over ISO MPEG-2 Transport Streams (TS).  The MPEG-2 TS has
   been widely accepted not only for providing digital TV services but
   also as a subnetwork technology for building IP networks.  Examples
   of systems using MPEG-2 include the Digital Video Broadcast (DVB) and
   Advanced Television Systems Committee (ATSC) Standards for Digital
   Television.

   The document identifies the need for a set of Internet standards
   defining the interface between the MPEG-2 Transport Stream and an IP
   subnetwork.  It suggests a new encapsulation method for IP datagrams
   and proposes protocols to perform IPv6/IPv4 address resolution, to
   associate IP packets with the properties of the Logical Channels
   provided by an MPEG-2 TS.
