摘要
基于SMPTE 272M标准,提出了在标准清晰度视频信号中加嵌和解嵌音频信号的硬件实现方案,详细分析了这两种系统的组成工作原理与设计过程,并介绍了音频加解嵌在数字广播系统中的应用。
The hardware system architectures of audio multiplexing and demultiplexing in standard definition video signals based on SMPTE 272M are proposed. And then, the working principles and design processing of these two systems are analyzed in detail. Finally, the application of audio multiplexing and demultiplexing in digital broadcasting system is described.
