新的！IEC 61937-3:20 17作为IEC 61937-3:20 17 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC？61937-3:20 17描述了用于传送根据AC-3和增强型AC-3格式编码的非线性PCM比特流的方法。IEC第三版？61937-3取消并取代2007年出版的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)移除对采样频率为32kHz的增强型AC-3比特流的支持；b)更新规范性和信息性参考资料；c)澄清增强AC-3比特流的暂停数据突发使用。

NEW!IEC 61937-3:2017 is available as IEC 61937-3:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC？61937-3:2017 describes the method used to convey non-linear PCM bitstreams encoded according to the AC-3 and enhanced AC-3 formats.？This third edition of IEC？61937-3 cancels and replaces the second edition published in 2007. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) removal of support for enhanced AC-3 bitstreams with a sampling frequency of 32 kHz;
b) updates to normative and informative references;
c) clarification of pause data-burst usage for enhanced AC-3 bitstreams.
