摘　　要：地面、卫星等数字电视广播系统大多采用MPEG-2传送流（TS流）传输数字电视信号,接收端需要从复合TS流中分解出用户所选择的节目流.提出了TS流解复用功能的一种实现方法,并对性能进行了测试分析.该方法可应用于现有电视机顶盒（STB）升级硬盘录像（PVR）功能方案中,以及数字广播电视信号监测系统等领域中.Ground and satellite digital TV broadcast system mostly adopt Transport Stream to transmit the signal, and from the multiplex Transport Stream, the receiving terminal needs to disassemble the stream of programs which the user has selected. The paper presents an implement method of demuhiplex and gives the test analysis of its capability. This method can be used in Set Top Box＇s upgrading to Personal Video Record, and also in the fields as the monitor system of digital broadcast television signal.
