1. A method of constructing a merge candidate list, comprising:

  • checking availability of spatial merge candidates;

    checking availability of a temporal merge candidate;

    constructing the merge candidate list using available spatial and temporal merge candidates; and

    adding one or more candidates if the number of available spatial and temporal merge candidates is smaller than a predetermined number,wherein 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 the current block, andif the current block is a second prediction unit partitioned by asymmetric partitioning, the spatial merge candidate corresponding to a first prediction unit partitioned by the asymmetric partitioning is set as unavailable.
