Patent number: 11985314Abstract: Video processing methods and apparatuses in a video encoding or decoding system for processing out-of-bounds nodes in a current picture. An out-of-bounds node is a coding tree node with a block region across a current picture boundary. The video processing method or apparatus determines an inferred splitting type, applies the inferred splitting type to split the out-of-bounds node into child blocks, adaptively splits each child block into one or multiple leaf blocks, and encodes or decodes the leaf blocks in the out-of-bounds node inside the current picture. The inferred splitting type for partitioning out-of-bounds nodes in an inter slice, picture, or tile is the same as the inferred splitting type for partitioning out-of-bounds nodes in an intra slice, picture, or tile.Type: GrantFiled: December 24, 2019Date of Patent: May 14, 2024Assignee: HFI INNOVATION INC.Inventors: Chia-Ming Tsai, Chih-Wei Hsu, Tzu-Der Chuang, Ching-Yeh Chen, Yu-Wen Huang, Shih-Ta Hsiang

Patent number: 11985324Abstract: Exemplary video processing methods and apparatuses for encoding or decoding a current block by inter prediction are disclosed. Input data of a current block is received and partitioned into sub-partitions and motion refinement is independently performed on each sub-partition. A reference block for each sub-partition is obtained from one or more reference pictures according to an initial motion vector (MV). A refined MV for each sub-partition is derived by searching around the initial MV with N-pixel refinement. One or more boundary pixels of the reference block for a sub-partition is padded for motion compensation of the sub-partition. A final predictor for the current block is generated by performing motion compensation for each sub-partition according to its refined MV. The current block is then encoded or decoded according to the final predictor.Type: GrantFiled: March 13, 2020Date of Patent: May 14, 2024Assignee: HFI INNOVATION INC.Inventors: Yu-Cheng Lin, Chun-Chia Chen, Chih-Wei Hsu, Ching-Yeh Chen, Tzu-Der Chuang, Yu-Wen Huang

Patent number: 11979593Abstract: Method and apparatus for affine CPMV or ALF refinement are mentioned. According to this method, statistical data associated with the affine CPMV or ALF refinement are collected over a picture area. Updated parameters for the affine CPMV refinement or the ALF refinement are then derived based on the statistical data, where a process to derive the updated parameters includes performing multiplication using a reduced-precision multiplier for the statistical data. The reduced-precision multiplier truncates at least one bit of the mantissa part. In another embodiment, the process to derive the updated parameters includes performing reciprocal for the statistical data using a lookup table with (m?k)-bit input by truncating k bits from the m-bit mantissa part, and contents of the lookup table includes m-bit outputs. m and k are positive integers.Type: GrantFiled: April 25, 2022Date of Patent: May 7, 2024Assignee: MEDIATEK INC.Inventors: Shih-Chun Chiu, Tzu-Der Chuang, Ching-Yeh Chen, Chun-Chia Chen, Chih-Wei Hsu, Yu-Wen Huang

Patent number: 11973985Abstract: Various schemes pertaining to pre-encoding processing of a video stream with motion compensated temporal filtering (MCTF) are described. An apparatus determines a filtering interval for a received raw video stream having pictures in a temporal sequence. The apparatus selects from the pictures a plurality of target pictures based on the filtering interval, as well as a group of reference pictures for each target picture to perform pixel-based MCTF, which generates a corresponding filtered picture for each target picture. The apparatus subsequently transmits the filtered pictures as well as non-target pictures to an encoder for encoding the video stream. Subpictures of natural images and screen content images are separately processed by the apparatus.Type: GrantFiled: August 22, 2022Date of Patent: April 30, 2024Assignee: MediaTek Inc.Inventors: Chih-Yao Chiu, Chun-Chia Chen, Chih-Wei Hsu, Tzu-Der Chuang, Ching-Yeh Chen, Yu-Wen Huang

Patent number: 11956421Abstract: Method and apparatus of video coding are disclosed. According to one method, in the decoder side, a predefined Intra mode is assigned to a neighboring block adjacent to the current luma block when the neighboring block satisfies one or more conditions. An MPM (Most Probable Mode) list is derived based on information comprising at least one of neighboring Intra modes. A current Intra mode is derived utilizing the MPM list. The current luma block is decoded according to the current Intra mode According to another method, a predefined Intra mode is assigned to a neighboring block adjacent to the current luma block if the neighboring block is coded in BDPCM (Block-based Delta Pulse Code Modulation) mode, where the predefined Intra mode is set to horizontal mode or vertical mode depending on prediction direction used by the BDPCM mode.Type: GrantFiled: May 7, 2020Date of Patent: April 9, 2024Assignee: HFI INNOVATION INC.Inventors: Man-Shu Chiang, Chih-Wei Hsu, Tzu-Der Chuang, Ching-Yeh Chen, Yu-Wen Huang, Shih-Ta Hsiang

Patent number: 11924444Abstract: Method and apparatus for constrained de-blocking filter are disclosed. One method receives input data related to a current block in a current picture at a video encoder side or a video bitstream corresponding to compressed data including the current block in the current picture at a video decoder side, and determines a first boundary associated with the current block, wherein the first boundary corresponds to one vertical boundary or one horizontal boundary of the current block. The method then applies de-blocking process to a reconstructed current block corresponding to the current block to result in a filtered-reconstructed current block, using a plurality of first reference samples at a same side of the first boundary, and replaces a first set of the first reference samples by one or more padding values. The method then generates a filtered decoded picture including the filtered-reconstructed current block.Type: GrantFiled: April 11, 2022Date of Patent: March 5, 2024Assignee: HFI INNOVATION INC.Inventors: Chia-Ming Tsai, Chih-Wei Hsu, Ching-Yeh Chen, Tzu-Der Chuang, Yu-Wen Huang
