Patent number: 11265537Abstract: A method of palette management for palette coding in a video coding system receives input data associated with a current block in a high-level picture structure and initializes a palette predictor in the high-level picture structure before a corresponding palette of a first palette-coded block in the high-level picture structure is coded. If a palette mode is selected for the current block, the method applies the palette coding to the current block using a current palette and updates the palette predictor based on the current palette to generate an updated palette predictor for a next block coded in the palette mode.Type: GrantFiled: June 11, 2020Date of Patent: March 1, 2022Assignee: HFI Innovation Inc.Inventors: Wang-Lin Lai, Yu-Chen Sun, Shan Liu, Xiaozhong Xu, Tzu-Der Chuang, Ding-Yun Chen, Yu-Wen Huang

Patent number: 10979726Abstract: A method and apparatus perform palette coding of a block of video data by initializing the palette or triplet palette or using a selected palette or triplet palette from a preceding image area for the beginning block of the current image area. The method receives input data associated with a current image area consisting of multiple blocks. For the beginning block, coding palette predictor is determined based on an initial palette or triplet palette or based on a selected palette or triplet palette associated with a selected block located at a location before the end of a preceding image area. For blocks of the current image area, palette coding is applied to the blocks, where at least one block uses the palette predictor for the beginning block as the palette predictor.Type: GrantFiled: April 22, 2019Date of Patent: April 13, 2021Assignee: HFI Innovation Inc.Inventors: Tzu-Der Chuang, Wang-Lin Lai, Yu-Chen Sun, Shan Liu, Xiaozhong Xu, Yu-Wen Huang, Ding-Yun Chen
