Abstract

   This document specifies the packetization scheme for encapsulating

   the compressed digital video data streams commonly known as "DV" into

   a payload format for the Real-Time Transport Protocol (RTP).

1. Introduction

   This document specifies payload formats for encapsulating both

   consumer- and professional-use DV format data streams into the Real-

   time Transport Protocol (RTP), version 2 [6].  DV compression audio

   and video formats were designed for helical-scan magnetic tape media.

   The DV standards for consumer-market devices, the IEC 61883 and 61834

   series, cover many aspects of consumer-use digital video, including

   mechanical specifications of a cassette, magnetic recording format,

   error correction on the magnetic tape, DCT video encoding format, and

   audio encoding format [1].  The digital interface part of IEC 61883

   defines an interface on an IEEE 1394 network [2,3].  This

   specification set supports several video formats: SD-VCR (Standard

   Definition), HD-VCR (High Definition), SDL-VCR (Standard Definition -

   Long), PALPlus, DVB (Digital Video Broadcast) and ATV (Advanced

   Television).  North American formats are indicated with a number of

   lines and "/60", while European formats use "/50".  DV standards

   extended for professional use were published by SMPTE as 306M and

   314M, for different sampling systems, higher color resolution, and

   faster bit rates [4,5].

   There are two kinds of DV, one for consumer use and the other for

   professional.  The original "DV" specification designed for

   consumer-use digital VCRs is approved as the IEC 61834 standard set.

   The specifications for professional DV are published as SMPTE 306M

   and 314M.  Both encoding formats are based on consumer DV and used in

   SMPTE D-7 and D-9 video systems.  The RTP payload format specified in

   this document supports IEC 61834 consumer DV and professional SMPTE

   306M and 314M (DV-Based) formats.

   IEC 61834 also includes magnetic tape recording for digital TV

   broadcasting systems (such as DVB and ATV) that use MPEG2 encoding.

   The payload format for encapsulating MPEG2 into RTP has already been

   defined in RFC 2250 [7] and others.

   Consequently, the payload specified in this document will support six...
