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。
A realization scheme of DTV real-time multi-program multiplexer using high-speed DSP is introduced. System TI DSP DSPSMS320C6201 as the main processor, with a small amount of PLD, hardware and software design to take full advantage of the characteristics of DSP to achieve real-time multiplexing of audio, video and auxiliary data to MPEG-2 system layer transmission standard code stream . The system also features RS encoding and scrambling extensions. Because the system specification is mainly implemented by DSP software, it can be modified to suit different applications. The system has a complete debugging circuit, good maintainability.
