Published: — with international search report (Art. 21(3)) (54) Title: MULTI-HYPOTHESES MERGE MODE (57) : A multi-hypotheses motion prediction mode for video cod- ing is provided. Multi-hypotheses motion prediction conveys prediction for motion compensation based on a selection of multiple predictions for mo- tion compensation (hypotheses), which are respectively obtained using mo- tion predictors or MVP selected from a list of candidate motion predictors. When coding a block of pixels, a video coder implementing multi-hypotheses motion prediction selects a first motion predictor and a second motion pre- dictor from a list of candidate motion predictors for the block of pixels. The video coder encodes or decodes a motion prediction code word that identi- fies the first and second motion predictors. The video coder computes a com- bined prediction for motion compensation based on first and second sets of pixels that are obtained using the selected first and second motion predictors, respectively. The video coder encodes or decodes the block of pixels by using the combined prediction for motion compensation.
