Cross-component prediction in video coding
A system and method for decoding video. A first syntax element for a block of video data is received, a value of the first syntax element indicating one of a plurality of mapping functions to be used to determine a magnitude of a scaling parameter for cross-component prediction. A second syntax element for the block of video data is received, a value of the second syntax element corresponding to the magnitude of the scaling parameter, wherein receiving the second syntax element includes decoding the value of the second syntax element with a specific binarization method. The magnitude of the scaling parameter is determined using the one of the plurality of mapping functions indicated by the first syntax element and the value of the second syntax element. Cross-component prediction is performed for at least one component of the block video data using the determined magnitude of the scaling parameter.
