After obtaining a prediction for a current block using inter-prediction, block adaptive local weighted prediction (BAWP) can be used to adjust the prediction based on luminance (i.e., brightness) and/or chroma (i.e., color) differences between the current block and its reference block therewith improving the prediction quality and reducing the differences, which in turn can reduce the prediction residuals that are encoded.
Techniques that reduce the signaling costs associated with signaling BAWP for the luminance and chrominance components are described.
