摘要
设计了一种多路音频自动存储播放系统,该系统接收12路AES/EBU数字音频信号,采用MPEG-2TS生成音频复用TS流,并通过网络传输到指定的硬盘存储。根据播放指令,该系统可选择还原任意一路任意时段的数字音频,并送至播放单元播出。系统仿真和板上验证结果表明,所设计的系统实现了预定的功能。
A multi-channel audio automatic storing and playing system is designed based on MPEG-2 TS. This system receives 12 channels AES/EBU audio signals, generates an audio multiplex TS based on MPEG-2 TS format, and then transfers it to the assigned hard disk where it is stored. According to the playing instruction, this system recovers the digital audio signal of arbitrary channel at any time from multiplex TS. Both systematic simulation and onboard verifying indicate that this system has achieved expected functions.
