中文摘要：
为提高传输流复用器经济性，对数字电视系统中专用信息的提取、重构及系统层节目时间参考值的修正等关键技术进行研究，提出了多路传输流软件复用的具体解决方案．应用VC＋＋开发环境设计实现了多路传输流分析与复用软件系统．测试结果表明，软件复用速率达40Mb／s，远高于一路传输码流的速度．
英文摘要：
To improve transport stream multiplexer economy, software multiplexing scheme of multiple transport streams was developed. Key technologies of retrieval and reorganization for digital video program specific information and regulation for program clock reference value were discussed. The transport stream analyzer and multiplexer software system was developed based on Visual C ＋ ＋ development environment. Test results show that the software multiplexing rate reaches 40 Mb/s, which is greatly faster than a transprot stream speed, and effectiveness of the proposed software scheme is demonstrated.
