数字音频接口.第1部分:总则

[中文适用范围]： 本部分 IEC 60958 描述了一种用于消费类和职业类应用数字音频设备互连的串行、单向、自时钟接口。它提供了该接口的基本结构。单独的文档定义了特定于特定项目的具体项目。该接口主要用于携带使用线性 PCM 编码且每个样本分辨率高达 24 位的单声道或立体声节目。当用于其他目的时，该接口能够携带非线性 PCM 编码的音频数据。还 provisions 该接口用于携带与计算机软件、多媒体技术相关的信号或使用非线性 PCM 编码的信号。这些应用的形式规范不是本文件的一部分。该接口旨在在 32 kHz 及以上的音频采样频率下运行。节目传输的同时也传输辅助信息。 [外文原描述]： IEC 60958-1:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60958-1:2021 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. When used for other purposes, the interface is able to carry audio data coded other than as linear PCM coded audio samples. Provision is also made to allow the interface to carry data related to computer software, multimedia technologies, or signals coded using non linear PCM. The format specification for these applications is not part of this document. The interface is intended for operation at audio sampling frequencies of 32 kHz and above. Auxiliary information is transmitted along with the programme. IEC 60958-1:2021c ancels and replaces the third edition published in 2008, and Amendment 1:2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The relevant part of IEC 60958-5 is supported.
