复用器配置软件设计与实现

摘要

介绍了复用器的主要功能,分析了系统PSI和SI信息,在此基础上提出了复用器配置软件的设计方案.复用器配置软件负责显示节目信息,提供良好的交互界面,解决节目号和PID号重复的问题,并根据用户配置重新生成PSI和SI数据以及完成TS包封装工作.通过使用复用器配置软件,能够对数量较多的复用器进行统一配置和管理,同时降低了复用器硬件部分的负担以及开发难度.设计基于PC机,使用VC++平台进行开发,经过实际测试,证明了设计的可行性和有效性.%In this paper, the function of muxtiplexer is given, the PSI and SI data are analyzed and the design of config software for the muxtiplexer is introduced. The software shows the information of program and offer the interface. The clash of program number and PID number are solved, packet the PSI and SI data to TS data. Configing a lot of mutiplexers will be easy by using this software. The cost of the mutiplexer device can be also reduced. This implementation is based on the PC, and the VC++ develop kit is used. The testing prove the feasibility and validity of this implementation.
