UNIFIED MERGE MODE AND ADAPTIVE MOTION VECTOR PREDICTION MODE CANDIDATES SELECTION

摘要

PROBLEM TO BE SOLVED: To provide a unified candidate block set for both an adaptive motion vector prediction (AMVP) mode and a merge mode for use in inter-prediction.SOLUTION: A method of encoding a motion vector comprises: determining one of a plurality of modes for a motion vector prediction process for a current block of video data; and performing the motion vector prediction process for the current block using the determined mode and a set of candidate blocks. The set of candidate blocks is the same for each of the plurality of modes. One candidate block in the set of candidate blocks is designated as an additional candidate block. The additional candidate block is used in the motion vector prediction process if another of the candidate blocks of the set of candidate blocks is unavailable.SELECTED DRAWING: Figure 7
