数字电视节目存储设计与实现

为了能够实时收看电视节目并同时能对其视频存储和码流分析,采用数字多媒体接收卡,进行程序设计获取电视信号TS流中的PMT表,得到节目的PID信息,成功地实现了数字电视节目的硬盘视频存储。文中提出的电视节目存储方法可以为码流分析或节目复用提供节目源,也可为个人存储有线或卫星电视节目提供极大方便。

Design and realization of DTV program storing

In order to get video record and TS analysis of television program without disturbing its reception in real-time and simultaneously,programs were designed in this paper to acquire the PMT in the television signal TS.Then PID information of program can be captured,thus realizing visual storing of DTV program successfully.This method can provide program source for TS analysis and multiplexer,and offer tremendous convenience for individuals to record cable or satellite DTV program.
