CATV网络MPEG-2系统目标解码器在DirectShow上的设计与实现

Design and Implementation of MPEG-2 System Target Decoder with DirectShow on the CATV Network

提出了一种用MicrosoftDirectShow的图形编辑滤波器来实现CATV网络MPEG - 2的系统目标解码器模型的设计方法。通过对STD两种结构 :程序流STD和传输流STD的具体分析和仿真 ,基本解决了STD模型具体实现的不同参数的设置问题。最后对原始流缓冲EB的实时仿真结果也基本符合MPEG - 2对STD的设计要求。

This paper proposes an implementation method of MPEG-2 System Target Decoder (STD) with Microsoft DirectShow graph editor. This proposed method solves the different parameters loaded problems during designing the STD system by further analyzing and real-time simulating the PS-STD and TS-STD structures. Eventually,the results from observing the Elementary Stream Buffer (EB) during the decode process show the designing demand of MPEG-2 STD.
