摘要： 目前基于DirectShow 的MPEG-2 流式播放器一般都工作在拉模式，这导致了源Filter 的设计较为复杂，而且并没有体现出流媒体应用的优点，因此该文提出了一种工作在推模式下的MPEG-2 传送流解复用滤波器的设计方法，经实验表明，该Filter 能够满足解码器的实时要求，解码后播放的效果十分流畅。

Abstract: At present, the MPEG-2 stream player works with the pull mode based DirectShow, which brings about the complexity of souce filter and can’t show it’s advantages in application. So the paper presents a MPEG-2 transport stream demultiplexer filter with push mode. The MPEG-2 demultiplexer which satisfies the decoder’s real time need, and obtains good playback effect.
