Claim 14:
15. A non-transitory computer-executable component in which a computer-executable component configured to be executed in one or more processors of a computing device is stored, wherein the computer-executable component is configured to:
generate a merge index of a current block;
obtain motion information and bi-directional prediction weight information for inter prediction of the current block from a merge candidate in a merge candidate list of the current block indicated by the merge index;
derive a prediction sample of the current block based on the motion information and the bi-directional prediction weight information; and
update a history-based motion vector predictor (HMVP) candidate list based on an HMVP candidate including the motion information and the bi-directional prediction weight information,
wherein the motion information includes a first reference index and a first motion vector related to a first reference picture, and a second reference index and a second motion vector related to a second reference picture,
wherein the bi-directional prediction weight information is used to derive a first weight value applied to a first prediction sample from the first reference picture and a second weight value applied to a second prediction sample from the second reference picture, and
wherein based on that a number of the merge candidates included in the merge candidate list is greater than or equal to 15, the merge index is inversely binarized based on a binarization method of adding a fixed 3 bits to a truncated unary of the merge index.
