| 摘 要： | 介绍了一种采用高速ＤＳＰ的ＤＴＶ实时多节目复用器的实现方案。系统以ＴＩ通用定点ＤＳＰＴＭＳ３２０Ｃ６２０１为主处理器，配合少量ＰＬＤ，硬件和软件设计充分利用ＤＳＰ的特点，实现将多路音频、视频和辅助数据实时复用成符合ＭＰＥＧ－２系统层传输规范的码流。系统还具有ＲＳ编码功能和加扰扩展功能。由于系统规范主要由ＤＳＰ软件实现，因而能通过修改软件以适合不同的应用场合。系统具有完备的调试电路，良好的可维护性。

| Abstract: | An implementation of DTV real-time multiplexer using high-speed DSP was introduced in this paper. System uses the general fixed point Digital Signal Processor TMS320C6201 of TI as main processor, PLD as coprocessor. Taking advantage of hardware and software designing with DSP, it can multiplex multiply audio, video and auxiliary data according with MPEG-2 transport stream packet layer in real time. The multiplexer can output RS coded stream. It has extended function of data scrambling. Since it is realized by software of DSP mainly,the system can fit many different situations by modifying software conveniently. Also the maintainability of this system is good with full on--board test circuit. |
