Abstract
This disclosure relates generally to video coding/decoding and particularly for enhancing block adaptive weighted prediction. One method includes receiving a coded video bitstream comprising a current block of a current frame and a first syntax element indicating a prediction mode for the current block, a plurality of scaling factor look-up tables being stored and comprising different ranges of scaling factors, wherein step sizes of the scaling factors or precisions of the scaling factors for each look-up table in the plurality of scaling factor look-up tables are same; determining the prediction mode based on a value of the first syntax element, wherein the prediction mode is used for predicting the current block based on a reference block of a reference frame; determining a scaling factor from one of the plurality of scaling factor look-up tables; and reconstructing the current block based on the reference block and the determined scaling factor.
