摘要
分析了DVB系统中TS流系统级复用原理,对其节目专用信息的提取和重构及系统层节目时钟参考值的修正等关键技术进行研究,设计并实现了多路TS流分析与复用软件系统。测试结果表明软件复用速率远高于单路TS流的速度,该软件复用方案是有效可行的。
System-level multiplexing principle of TS（Transport Stream）in DVB（Digital Video Broadcasting） system is analyzed. The key technologies of retrieval and reorganization for program specific information and regulation for program clock reference value in system layer are discussed in detail. And then, a software system is designed and implemented to analyze and multiplex the TS. The testing results show that the software muhiplexing rate is greatly faster than a single TS speed and the proposed software scheme is effective and feasible.
