  • Patent number: 11240526
    Abstract: Disclosed are a method and apparatus for decoding an image using inter-prediction. The method of decoding an image using inter-prediction includes receiving a bitstream; acquiring a portion of information indicating a motion vector of a current block to be decoded in the received bitstream, obtaining the motion vector of the current block by using the acquired information to determine the remaining information other than the portion, and generating a prediction block for the current block through inter-prediction that uses the motion vector of the current block. Therefore, it is possible to improve image decoding/encoding efficiency.
