DVB APPROVES NEW GUIDELINES FOR H.264/AVC
VIDEO & HIGH EFFICIENCY AAC AUDIO CODECS
H.264/AVC for SDTV & HDTV
Geneva – 2 November 2004 – The DVB Steering Board has approved a revision to
its well known implementation guidelines for audio and video codecs over a
broadcast Transport Stream to include the option of both H.264/AVC video and High
Efficiency AAC (HE-AAC) audio codecs. The revision to the European
Telecommunications Standards Institute (ETSI) document (TS 101 154) will now be
forwarded to ETSI for standardisation and will be published shortly. Upon publication
it will be available for download via: www.etsi.org.
The new document mandates support of Main Profile for H.264/AVC SDTV
receivers, with an option for the use of High Profile. The support of High Profile is
mandated for H.264/AVC HDTV receivers.
Entitled "Implementation guidelines for the use of Video and Audio Coding in
Broadcasting Applications based on the MPEG-2 Transport Stream", the latest
addition to the DVB family of standards is designed to promote interoperability
between transmissions and receivers by describing a set of requirements for
implementing the codecs in a Transport Stream, i.e. the traditional DVB broadcast
environment used in cable, satellite and terrestrial transmissions.
Peter MacAvock, DVB’s Executive Director said: “This document is one of the most
important DVB documents, and a key to ensuring the interoperability of DVB
equipment and transmissions. It is the basis of all MPEG-2 DVB decoders in the
market. The addition of H.264/AVC and HE-AAC paves the way for using these
exciting codecs in mainstream DVB applications like HDTV.”
Previously, the document included MPEG-2 video, MPEG-1 Layer II audio, Dolby
AC-3 audio, and DTS audio. This revision of the document adds H.264/AVC video
(MPEG-4 Part 10) and High Efficiency Advanced Audio Coding (HE-AAC) to the
range of codecs that may be used in DVB applications. Both H.264/AVC and HEAAC
bring substantial improvements in coding efficiency over MPEG-2 and
associated audio codecs, and are the subject of much interest, especially for
prospective new HDTV services.

Audio Codecs
A separate specification, TS 102 005, covers the use of audio and video codecs for
the delivery of DVB services directly over IP networks (without Transport Stream).
