Claim 3:
4. A video encoding method comprising the steps of:
determining whether or not to apply a combined prediction mode to a current block;
obtaining a first prediction block and a second prediction block for the current block when the combined prediction mode is applied to the current block, wherein the first prediction block is obtained based on motion information of a merge candidate of the current block, and the second prediction block is obtained based on an intra prediction mode of the current block; and
obtaining a third prediction block for the current block based on a weighted sum operation of the first prediction block and the second prediction block,
wherein when at least one among a width and a height of the current block is greater than a threshold value, the combined prediction mode is not applied to the current block; wherein in performing the weighted sum operation, weighting values applied to the first prediction block and the second prediction block are determined based on prediction modes of neighboring blocks adjacent to the current block; wherein when the combined prediction mode is applied to the current block, triangular partitioning is disabled for the current block.
