Abstract
A method of decoding video data performed by an electronic device is provided. The method receives the video data and determines a block unit from a current frame included in the video data. The method determines a first chroma prediction block of the block unit based on a luma vector of the block unit, and determines a second chroma prediction block of the block unit using a cross-component filter based on a reconstructed luma block of the block unit. The method determines, from the video data, a weighting index for selecting, from multiple predefined parameters, multiple weighting parameters of the first chroma prediction block and the second chroma prediction block based on the weighting index. The method reconstructs the block unit based on the first chroma prediction block, the second chroma prediction block, and the weighting parameters.
