标准范围

IEC 61937-2:20 07规定了应用IEC 60958-1和IEC 60958-3传送非线性PCM编码音频比特流的数字音频接口。该标准规定了burst-info，其定义了关于包含在突发有效载荷中的数据的内容信息。第二版取消并取代了2000年出版的第一版。与上一版相比，此版本包含以下重大技术变更:a)添加了新的音频数据类型:增强型AC-3数据、MPEG-2 AAC低采样频率、MPEG-4 AAC、DTS类型IV、ATRAC-X、WMA professional和MAT。b)Pc中的数据类型字段从位0-4扩展到0-6。这个双语版本对应于2007-05年出版的单语英文版。

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.
