Statistical correlations of the smoothness and consistency in images were used to develop error concealment techniques for I-frame, P-frame, and B-frame MPEG-2.
同时基于图像信号的相关性、光滑性及一致性的假设，分别对MPEG-2的I-帧、P-帧和B-帧图像提出了相应的错误隐藏技术。
The proposed method can detect scene boundaries through using various macroblock type of B-frame and P-frame in MPEG video flow in order to realize accurate scene change positioning.
该算法只需要通过直接抽取MPEG视频流中的B帧、P帧中的宏块类型信息，并对其进行计算就可以检测出视频中存在的镜头边界，从而对场景变换进行精确定位。
We took MVC design mode and B/S mode into application of system logic frame, and so the problems of complicated logic that is aroused by kinds of mode, various data and complex alternation.
