数字音频接口.第1部分:总则

[中文适用范围]： IEC 60958 的这一部分描述了一种串行、单向、自计时接口，用于消费类和专业应用的数字音频设备的互连。它提供了接口的基本结构。单独的文档定义特定于特定应用程序的项目。该接口主要用于传输单声道或立体声节目，使用线性 PCM 进行编码，每个样本的分辨率高达 24 位。当用于其他目的时，该接口能够传输除线性 PCM 编码音频样本之外的音频数据。还规定允许接口承载与计算机软件相关的数据或使用非线性PCM编码的信号。这些应用程序的格式规范不属于本标准的一部分。该接口适用于 32kHz 及以上音频采样频率的操作。辅助信息与节目一起传输。 [外文原描述]： IEC 60958-1:2008 describes a serial, uni-directional, self-clocking interface for the interconnection of digital audio equipment for consumer and professional applications. It provides the basic structure of the interface. Separate documents define items specific to particular applications. The interface is primarily intended to carry monophonic or stereophonic programmes, encoded using linear PCM and with a resolution of up to 24 bits per sample. This third edition cancels and replaces the second edition published in 2004 and constitutes a technical revision. It includes the following significant technical changes with respect to the previous edition: Electrical and optical requirements are removed from IEC 60958-3; they are specified in IEC 60958-1.
