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.

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.

1. Introduction

ISO/IEC JTC1/SC29 WG11 (also referred to as the MPEG committee) has

defined the MPEG1 standard (ISO/IEC 11172)[1] and the MPEG2 standard

(ISO/IEC 13818)[2]. This memo describes a packetization scheme to

transport MPEG video and audio streams using the Real-time Transport

Protocol (RTP), version 2 [3, 4].

The MPEG1 specification is defined in three parts: System, Video and

Audio. It is designed primarily for CD-ROM-based applications, and

is optimized for approximately 1.5 Mbits/sec combined data rates. The

video and audio portions of the specification describe the basic

format of the video or audio stream. These formats define the

Elementary Streams (ES). The MPEG1 System specification defines an

encapsulation of the ES that conta...
