1. A video decoding method comprising:
determining an available information about adjacent blocks comprising a right adjacent block according to a coding order;
when a first adjacent block corresponding to motion vector resolution is the right adjacent block, the right adjacent block is available according to the available information, and a motion vector of the right adjacent block exists, obtaining a motion vector predictor of a current block using the motion vector of the right adjacent block;
when a motion vector of the right adjacent block does not exist, obtaining a default motion vector using at least one motion vector of the adjacent blocks comprising an upper adjacent block and a left adjacent block;
obtaining a motion vector predictor of the current block using the default motion vector;
obtaining a motion vector of the current block using the motion vector predictor of the current block.
