适用于PCM实现的可逆过程 将两个音频信号转换为一个音频信号的编码器/解码器系统 PCM信号兼容，525线/60字段 或625线/50野外电视系统。建立信号 PCM编码器-解码器的格式，用于在 消费者录像带系统上的PCM表单。确保标准化 编码器/解码器系统的系统操作兼容性和 录音带与播放机和系统的互换性。

Applies to the reversible process achieved by the PCM encoder/decoder system that transforms two audio signals into one PCM signal for compatibility, with either 525 line/ 60 field or 625 line/50 field television system. Establishes the signal format for the PCM encoder decoder for reproducing audio signals in PCM form on a consumer video cassette system. Ensures standardized system operation compatibility of encoder/decoder systems and interchangeability of recorder tapes with players and systems.
