1.范围1。1本标准规定了在MPEG-2传输流中传输AES3数据的方法 电视应用。对于这些电视应用，AES3的帧速率为48 kHz。1.2某些应用可能需要线性PCM（脉冲编码调制）数字音频与 MPEG-2 4:2:2配置文件中指定的压缩视频。MPEG音频标准定义了压缩音频 音频，但不定义MPEG-2传输系统中传输的未压缩音频。这个标准 增强了MPEG标准，以满足承载AES3流的要求，其中可能包括 线性PCM音频（采样率为48 ksample/s）或AES3格式内携带的数据。

1 Scope1.1 This standard specifies the method of transporting AES3 data in an MPEG-2 transport stream for television applications. For these television applications, the AES3 frame rate is 48 kHz.1.2 Some applications may require linear PCM (pulse code modulated) digital audio in conjunction with compressed video specified in the MPEG-2 4:2:2 profile. The MPEG audio standard defines compressed audio, but does not define uncompressed audio for carriage in an MPEG-2 transport system. This standard augments the MPEG standards to address the requirement to carry AES3 streams, which may consist of linear PCM audio (at 48 ksample/s), or data carried within the AES3 format.
