Classification: CPC H | IPC H

Claim 9:
10. A decoder apparatus for video decoding, comprising:
processing circuitry configured to:
decode coded information for a current block from a coded video bitstream, the coded information indicating a bi-prediction motion compensation mode for the current block;
rank, based on current neighboring reconstructed samples of the current block, first neighboring reconstructed samples of a first prediction block, and second neighboring reconstructed samples of a second prediction block, plural pre-defined weights used in the bi-prediction motion compensation mode;

select one of the plural pre-defined weights based on an index included in the coded information; and
reconstruct samples in the current block based on a weighted average of corresponding samples in the first prediction block and the second prediction block using the selected weight.
