标准摘要
[中文适用范围]： IEC 60958 的这一部分指定了与音频内容相关并随其携带的元数据或子代码的编码格式。 IEC 60958 的这一部分与 IEC 60958-1、IEC 60958-4-1 和 IEC 60958-4-4 一起规定了一种接口，用于从一个发射器对两个通道的周期性采样和线性表示的数字音频数据进行串行数字传输至一台接收器。 [外文原描述]： IEC 60958-4-2:2016 specifies the format for coding metadata, or subcode, that relates to the audio content and is carried with it. This part of IEC 60958, together with IEC 60958-1, IEC 60958-4-1, and IEC 60958-4-4, specifies an interface for serial digital transmission of two channels of periodically sampled and linearly represented digital audio data from one transmitter to one receiver. This first edition, together with IEC 60958-4-1 and IEC 60958-4-4, cancels and replaces IEC 60958-4 published in 2003 and its Amendment 1:2008 and constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60958-4:2003 with its Amendment 1:2008: - support for a wider range of physical media; - support for a wider range of audio sampling frequencies; - deprecation of "minimum implementation" of channel status data.
