WebInter prediction creates a prediction model from one or more previously encoded video frames. The model is formed by shifting samples in the reference frame (s) (motion compensated prediction). The AVC CODEC uses block-based motion compensation, the same principle adopted by every major coding standard since H. WebJan 1, 2014 · In HEVC, inter prediction is performed on the prediction block (PB) level [1, 2]. The corresponding prediction unit (PU) contains the information how inter prediction is performed. Inter prediction is called motion compensated prediction since shifted areas of the reference pictures are used for prediction of the current PB.
