Abstract: Methods and apparatuses for encoding and decoding video data. Techniques disclosed comprise obtaining a linear model used to encode or to decode a video block of the video data. The linear model is obtained by computing a parameter of the linear model as a function of a minimum chroma value and a maximum chroma value and as a function of a reciprocal of a difference between a minimum luma value and a maximum luma value, wherein the reciprocal is derived from a single look up table including values for determining least significant bits.
