PROBLEM TO BE SOLVED: To provide a favorable method of constructing a merge list.SOLUTION: A method comprises checking availability of spatial and temporal merge candidates, constructing a merge list using available spatial and temporal merge candidates, and adding one or more candidates if the number of the available spatial and temporal merge candidates is smaller than a predetermined number. The spatial merge candidate is motion information of a spatial merge candidate block, the spatial merge candidate block is a left block, an above block, an above-right block, a left-below block or an above-left block of a current block, and if the current block is a second prediction unit partitioned by asymmetric partitioning, a first prediction unit partitioned by the asymmetric partitioning is set as unavailable. Therefore, the coding efficiency of motion information is improved by removing unavailable merge candidates and adding new merge candidates to the merge candidates.SELECTED DRAWING: Figure 1 |
