Abstract:
Various embodiments for calculating a motion vector predictor for a current block are provided. A fixed number of motion vector predictor candidates is obtained, with the fixed number being at least two. Each of the motion vector predictor candidates is a candidate for the motion vector predictor. An index for identifying the motion vector predictor from among the fixed number of the motion vector predictor candidates is coded according to the fixed number and added to a bitstream. The motion vector predictor to be used for coding the current block is selected from among the fixed number of the motion vector predictor candidates based on the index. The fixed number of the motion vector predictor candidates includes a plurality of candidates each having a motion vector of value 0, and at least one of one or more first candidates and one or more new candidates.
