本标准定义了一种将多达八个符合AES3的同步数据流映射到自时钟串行接口的方法。当用于PCM数字音频时，该接口最多可携带16个线性编码音频和辅助数据通道。可选地或同时（在八流限制内），该接口可用于传输压缩音频流或打包成AES3兼容流的其他数据。该接口对封装在与多路复用同步的AES3兼容流中的任何数据类型都是透明的。

This standard defines a method of mapping up to eight synchronous streams of AES3-compliant data into a self-clocking serial interface. When used for PCM digital audio, the interface can carry up to 16 channels of linearly encoded audio and auxiliary data. Alternatively or concurrently (within the eight stream limit), the interface may be used to carry streams of compressed audio or other data that is packaged into an AES3- compliant stream. The interface is transparent to any data type that is packaged in an AES3-compliant stream that is synchronous with the multiplex.
