Abstract
Provided is a video decoding method comprising determining a first base motion vector of a current block for a first reference picture and a second base motion vector of the current block for a second reference picture, determining a first refinement motion vector by refining the first base motion vector by a first motion vector difference and determining a second refinement motion vector by refining the second base motion vector by a second motion vector difference, determining first and second prediction blocks of the current block based on the first refinement motion vector and the second refinement motion vector, and determining a final prediction block for the current block based on a weighted sum of the first prediction block and the second prediction block.
