Abstract

See full text

Provided is a video decoding method including: obtaining, from a bitstream, prediction motion vector information indicating a prediction motion vector of a current block and difference motion vector information indicating a difference motion vector of the current block; determining the prediction motion vector of the current block according to whether or not an adjacent block of the current block is decoded and the prediction motion vector information; determining a motion vector resolution of the current block according to whether or not the adjacent block of the current block is decoded; determining the difference motion vector of the current block according to the difference motion vector information; determining a motion vector of the current block according to the prediction motion vector, the motion vector resolution, and the difference motion vector; and reconstructing the current block according to the motion vector of the current block, wherein the adjacent block of the current block includes a right block of the current block.
