本标准通过参考AES67规定了通过IP网络实时传输基于RTP的PCM数字音频流。定义了一种基于SDP的信令方法，用于接收和解释流所需的元数据。包括压缩音频信号在内的非PCM数字音频信号不在本标准范围内。

This standard specifies the real-time, RTP-based transport of PCM digital audio streams over IP networks by reference to AES67. An SDP-based signaling method is defined for metadata necessary to receive and interpret the stream.Non-PCM digital audio signals including compressed audio signals are outside the scope of this standard.
