Abstract
Provided is a video encoding and decoding method and apparatus. The video encoding method includes selecting a plurality of reference blocks based on a plurality of motion vectors and setting weights assigned to the plurality of reference blocks independently for each of a plurality of regions of a current block in order to predict and encode the current block, thereby providing a new encoding mode allowing accurate prediction of the current block and thus improving the compression rate of video encoding.
