Abstract
In the present disclosure, a video decoding method is provided, including obtaining differential motion vector size information indicating a size of a differential motion vector of a current block, obtaining a sign bit hiding flag indicating whether or not sign bit hiding of the differential motion vector of the current block is performed, determining a sign of the differential motion vector without obtaining differential motion vector sign information on the sign of the differential motion vector, when the sign bit hiding flag indicates that the sign bit hiding of the differential motion vector is performed, and determining the differential motion vector according to the size of the differential motion vector based on the differential motion vector size information and the determined sign of the differential motion vector.
