MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202527097591 A) filed by Mediatek Inc. on October 09, 2025, for Methods And Apparatus Of Inheriting Cross-Component Models From Rescaled Reference Picture In Video Coding.
Inventors include Tseng, Hsin-Yi; Chiang, Man-Shu; Tsai, Chia-Ming; Chuang, Cheng-Yen; Chen, Guan-Hao; Hsu, Chih-Wei; Chen, Yi-Wen; and Chuang, Tzu-Der.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: A method and apparatus for coding colour pictures or video using coding tools including one or more cross component models related modes are disclosed. According to this method, a collocated picture is selected from one or more reference picture lists according to one or more pre-defined rules. Whether the collocated picture selected is a RPR (Reference Picture Resampling) picture is determined. A current CCP (Cross-Component Prediction) model is derived from the collocated picture depending on whether the collocated picture is the RPR picture or not. The current second-colour block is encoded or decoded by using a candidate list comprising the current CCP model, wherein when the current CCP model is selected to code the current second-colour block, prediction data for the current second-colour block is generated by applying the current CCP model to the current first-colour block.
