  • Publication number: 20240129521
    Abstract: A moving picture decoding apparatus for decoding a current block of a picture is provided. A motion vector candidate list includes motion vector candidates. Each motion vector candidate includes a value. A second candidate is arranged before a first candidate in the motion vector candidate list. The first candidate is sorted before the second candidate in the motion vector candidate list based on the value of the first candidate and the value of the second candidate. An index identifying a motion vector candidate from the motion vector candidate list is decoded, and the current block is generated using the identified motion vector candidate. The value of the first candidate is higher than the value of the second candidate, and the value is based on a number of times the candidate is selected as a motion vector predictor for neighboring blocks.
