标准摘要
[中文适用范围]： IEC 60958 的这一部分指定了用于音频内容的音频编码格式。它与 IEC 60958-1、IEC 60958-4-2 和 IEC 60958-4-4 一起指定了一种接口，用于将两个通道的周期性采样和线性表示的数字音频数据从一个发送器串行数字传输到一个接收器。预计音频数据将以 AES5 识别的任何采样频率进行采样。接口指示其他采样率的能力并不意味着建议设备支持这些速率。为了消除疑问，设备规格应定义支持的采样频率。 [外文原描述]： IEC 60958-4-1:2016 specifies the format for coding audio used for the audio content. Together with IEC 60958-1, IEC 60958-4-2, and IEC 60958-4-4, it 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 60958-4-2 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.
