Inventors include Tseng, Hsin-Yi; Chiang, Man-Shu; Tsai, Chia-Ming; Chuang, Cheng-Yen; and Hsu, Chih-Wei.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: A method of performing cross-component prediction for coding pixel blocks is provided. A current block has a first-color block and a second-color block. A video coder generates a reconstruction for the first-color block. The video coder inherits a cross-component model from a reference block, where the cross-component model is propagated to the reference block based on cross-component prediction information of two or more further reference blocks of the reference block by e. g., selecting one reference block from the more than one further reference blocks to provide the cross-component model for the current block. The more than one further reference blocks may be located by motion vectors or block vectors of the reference block. The video coder applies the inherited cross-component model to the reconstruction of the first-color block to generate a cross-component prediction of the second-color block. The video coder uses the generated cross-component prediction to encode or decode the current block.
