Abstract
Various embodiments for coding a current block are provided. One or more candidates of a first type for a motion vector predictor for the current block are derived from first motion vectors of first blocks. A candidate of a second type for the motion vector predictor for the current block is derived. The candidate of the second type is different from the one or more candidates of the first type and includes a zero vector. The motion vector predictor for the current block is selected from among candidates including the one or more candidates of the first type and the candidate of the second type. The current block is predicted using the selected motion vector predictor. A bitstream is generated using the predicted current block. A total number of the one or more candidates of the first type is less than a maximum candidate number.
