The input of the algorithm is MPEG 2 video stream captured by a stationary camera. Then the algorithm tracks moving objects in the stream without decoding it.

对于输入的一组由静止摄像机捕获的MPEG - 2视频流，该算法不需对其进行解码即可对场景中的运动物体直接进行目标跟踪。

The standard only defined the decoding model, then the multiplex designing was very free, because it was demonstrated good if the output of it could be decoded by the MPEG-2 decoder.

这个标准中只定义解码模型，因此编码端的复用器的设计有很大的自由度，只要能够被MPEG-2解码器所解码就符合要求。
