Methods for processing video, communication equipment, and computer-readed materials that record in an immutant manifestation

Abstract

The invention relates to a video processing method, which consists of performing downsampling on the chromatic and chromatic samples of the neighboring block of the current video block; determining, for the variation between the current video block of the video block which is the chromatic block and the encoded representation of the video block, the parameters of a cross-component linear model (CCLM) based on the chromatic and chromatic samples obtained from the downsampling; Apply CCLM to the brightness samples placed within the brightness block corresponding to the current video block to infer predicted values ​​for the current video block; and perform transformations based on these predicted values.
