Abstract:
1. A video decoding method for predicting a current block using an inter prediction, the method comprising: obtaining, from encoded data, mode information indicating which motion vector encoding mode among a plurality of motion vector encoding modes is used for determining at least one motion vector of the current block; and when the obtained mode information indicates a first motion vector encoding mode among the plurality of motion vector encoding modes, performing a process comprising: wherein the one or more neighboring blocks are selected from at least one spatially neighboring block of the current block and at least one temporally neighboring block of the current block, and wherein, when the at least one temporally neighboring block is selected, the at least one temporally neighboring block is located within a reference picture included either in the first reference picture list or in the second reference picture list, and a position of the at least one temporally neighboring block within the reference picture is obtained based on a position of the current block within a current picture including the current block.
