Abstract

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.
