Claim 4:
5. The method according to claim 4, wherein the location coordinates of the top neighboring samples of the chroma block are (0, −1), (1, −1), . . . , and −(X−1, −1), wherein X represents the width of the chroma block; and
if the intra prediction mode corresponding to the chroma block is a cross-component linear mode above LMA, the location coordinates at the preset locations are (0, −1), (X/4, −1), (X−1−X/4, −1), and (X−1, −1), or (0, −1), (X/4, −1), (3*X/4, −1), and (X−1, −1).
