Title Digital audio - Interface for non-linear PCM encoded audio bitstreams applying IEC 60958 - Part 1: General
Project Number 23379
Abstract/Scope applies to the digital audio interface using the IEC 60958 series for the conveying of non-linear PCM encoded audio bitstreams. It describes the way in which this digital interface can be used in consumer applications. Cancels and replaces the first edition published in 2000. This edition contains the following significant technical changes with respect to the previous edition. - The data-type field in Pc is expanded from bit 0-4 to bit 0-6. - A new additional definition of Pd is specified. - The numbers of times for symbol frequency are changed to refer to each part of IEC 61937. - The requirement for burst spacing is changed.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
