Digital audio - Interface for non-linear PCM encoded audio bitstreams applying IEC 60958 - Part 2: Burst-info

IEC 61937-2:2007+A1:2011 specifies the digital audio interface to convey non-linear PCM encoded audio bitstreams applying IEC 60958-1 and IEC 60958-3. This standard specifies burst-info which defines content information about the data contained in the burst payload. This second edition cancels and replaces the first edition published in 2000. This edition contains the following significant technical changes with respect to the previous edition:
a) New audio data-types of enhanced AC-3 data, MPEG-2 AAC low sampling frequency, MPEG-4 AAC, DTS type IV, ATRAC-X, WMA professional and MAT are added.
b) Data-type field in Pc is expanded from bit 0-4 to 0-6. This bilingual version corresponds to the monolingual English version, published in 2007-05. This consolidated version consists of the second edition (2007) and its amendment 1 (2011). Therefore, no need to order amendment in addition to this publication.

Audionumérique - Interface pour les flux de bits audio à codage MIC non linéaire conformément à la CEI 60958 - Partie 2: Salve d'informations

La CEI 61937-2:2007+A1:2011 spécifie l'interface audionumérique pour acheminer des flux de bits audio à codage MIC non linéaire conformément à la CEI 60958-1 et à la CEI 60958-3. La présente norme spécifie la salve d'information qui définit le contenu d'informations sur les données contenues dans la charge-utile de salve. Cette deuxième édition annule et remplace la première édition publiée en 2000. La présente édition contient les importantes modifications techniques suivantes par rapport à l'édition précédente:
a) Les nouveaux types-de-données audio AC-3 amélioré, MPEG-2 AAC faible fréquence d'échantillonnage, MPEG-4 AAC, DTS type IV, ATRAC-X, WMA professional et MAT sont ajoutés.
b) Le champ type-de-données dans Pc est étendu des bits 0 à 4 aux bits 0 à 6. La présente version bilingue correspond à la version anglaise monolingue publiée en 2007-05.  Cette version consolidée comprend la deuxième édition (2007) et son amendement 1 (2011). Il n'est donc pas nécessaire de commander l'amendement avec cette publication.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

This consolidated version of IEC 61937-2 consists of the second edition (2007)
[documents 100/1115/CDV and 100/1221/RVC] and its amendment 1 (2011) [documents
100/1811/CDV and 100/1884/RVC]. It bears the edition number 2.1.
The technical content is therefore identical to the base edition and its amendment and
has been prepared for user convenience. A vertical line in the margin shows where the
base publication has been modified by amendment 1. Additions and deletions are
displayed in red, with deletions being struck through.

– 4 – 61937-2  IEC:2007+A1:2011
International Standard IEC 61937-2 has been prepared by technical area 4: Digital system
