Inventors include Hsiao, Yu-Ling; Chiu, Shih-Chun; Lin, Yu-Cheng; Hsu, Chih-Wei; Chen, Ching-Yeh; Chuang, Tzu-Der; Chen, Yi-Wen; and Huang, Yu-Wen.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: A method and apparatus for in-loop filtering of reconstructed video are disclosed. According to the method, reconstructed pixels are received, wherein the reconstructed pixels comprise a current block and the current block comprises a first-colour block and a second-colour block. A target fixed filter set is selected from multiple fixed filter sets according to filter-selection indication at a CTB (Coding Tree Block) level for filtering the current block using a target filter type from a filter-type group comprising chroma ALF (Adaptive Loop Filter), CCALF (Cross-Component ALF), or both. The target fixed filter set is applied to the current block to generate a filtered current block. The filtered current block is provided.
