本标准规定了使用AES3串行数字音频接口在专业应用中传输非PCM音频和数据的接口格式。本标准包括基于现有AES3格式的物理和逻辑规范，以允许在不同设备之间交换非PCM数据。该标准支持多种非PCM音频和数据格式，并允许在一个接口内传输多个数据流。本标准提供了承载时间代码或时间对齐信息的方法，以便通过该接口传输的信息可以与通过其他接口传输的信息内容同步。

This standard specifies an interface format for the transport of non-PCM audio and data in professional applications using the AES3 serial digital audio interface. This standard includes both physical and logical specifications, based on the existing AES3 format, to allow exchange of non-PCM data between different devices. The standard accommodates multiple non-PCM audio and data formats and allows carriage of multiple data streams within a single interface. This standard provides means for carrying time code or time alignment information so that the information conveyed over this interface may be synchronized with information content delivered over other interfaces.
