1. A method for decoding a video, comprising:
acquiring a first colour component neighboring reference value, a second colour component neighboring reference value and a first colour component reconstructed value corresponding to a current block, wherein the first colour component neighboring reference value is indicative of a first colour component parameter corresponding to a neighboring reference sample of the current block, the second colour component neighboring reference value is indicative of a second colour component parameter corresponding to the neighboring reference sample of the current block, and the first colour component reconstructed value is indicative of one or more reconstructed parameters of a first colour component corresponding to the current block;
generating a second colour component predicted value corresponding to the current block at least based on a linear model corresponding to factors, wherein the factors are determined by at least one of a weight coefficient, the first colour component neighboring reference value, or the second colour component neighboring reference value; and
decoding the video based on the second colour component predicted value.
