数字音频.用于IEC 60958的非线性脉冲编码调制(PCM)编码音频位流的接口.第2部分:脉冲串信息

[中文适用范围]： IEC 61970 的这一部分指定了应用 IEC 60958-1 和 IEC 60958-3 传输非线性 PCM 编码音频比特流的数字音频接口。该标准规定了突发信息，它定义了有关突发有效负载中包含的数据的内容信息。 [外文原描述]： IEC 61937-2:2007 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.
