介绍了ＭＰＥＧ－２研究平台的设计与实现，该平台建立在硬件编解码器的基础上，能够对活动图象和声音进行实时压缩编解码，编码后的码流既可以直接送给硬件解码器实时解码。也可以保存到硬盘上供将来回放，同时该平台还提供了基于ＷｉｎｄｏｗｓＮＴ的用户界面，用户可以修改ＭＰＥＧ－２的各种编码参数，得到优化的系统性能。
This paper introduces the design and realization of MPEG-2 research platform. The platform is based on hardware codec and can encode and decode the moving images and sound in real time. The encoded code stream can be directly sent to the hardware decoder Real-time decoding. It can also be saved to hard disk for future playback. At the same time, the platform also provides a Windows NT-based user interface. Users can modify various encoding parameters of MPEG-2 to obtain optimized system performance.
