Intra-frame prediction of predictive coding (intra-picture prediction)Predictive coding (prediction Coding) is one of the core techniques of video coding, which uses one or several coded sample values to predict the current sample

Inter-frame prediction of predictive coding (inter-picture prediction)Inter-frame prediction refers to the use of video time domain correlation, using neighboring encoded image pixels to predict the current image of the pixel, in order to effectively remove the video time domain redundancy. Since the video sequence usually includes strong time-domain correlation, the predicted residual value is close to 0,

The new H. 264 (MPEG-4 AVC) video coding standard can achieve considerably higher coding efficiencycompared to previous standards. this is usually mainly due to the consideration of variable block sizes formotion compensation, multiple reference frames, intra prediction, but also due to better exploitation of specified correlation that may exbetist ween adjacent limit, with the Skip mode in
