  • Patent number: 12114015
    Abstract: In a method and apparatus for video coding using Low-Frequency Non-Separable Transform (LFNST) mode, a coding unit (CU) is partitioned into one or more transform blocks (TBs). A syntax is determined at an encoder side or at a decoder side, where the determining step is performed by signaling the syntax at the encoder side or by parsing the syntax at the decoder side if one or more conditions are satisfied. The syntax indicates whether the LFNST mode is applied to the current CU and/or which LFNST kernel is applied when the LFNSF is applied, and the conditions comprise a target condition corresponding to that all target TBs in a target TB set have a TS mode indication as false, and the target TB set is selected from the TBs in the current CU. The current CU is encoded or decoded according to the LFNST mode.

  • Patent number: 12095993
    Abstract: A method and apparatus for video coding using a coding mode belonging to a mode group comprising an Intra Block Copy (IBC) mode and an Intra mode are disclosed. According to the present invention, for both IBC and Intra mode, a same default scaling matrix is used to derive the scaling matrix for a current block. In another embodiment, for the current block with block size of M×N or N×M, and M greater than N, a target scaling matrix is derived from an M×M scaling matrix by down-sampling the M×M scaling matrix to an M×N or N×M scaling matrix.

  • Publication number: 20240291985
    Abstract: Video processing methods and apparatuses in a video encoding or decoding system. A method receives input data associated with a current block in a current picture, determines if the current block is an out-of-bounds node, wherein the out-of-bounds node is a coding tree node of the current picture with a block region across a current picture boundary, and determines whether the current block is larger than a predefined size. The method further determines an inferred splitting type if the current block is an out-of-bounds node and the current block is larger than the predefined size and applies the inferred splitting type to split the current block into child blocks if the current block is an out-of-bounds node and the current block is larger than the predefined size, and then adaptively splitting each child block into one or more leaf blocks.

  • Patent number: 12069257
    Abstract: Video data processing methods and apparatuses receive input data associated with a current split node partitioned from a parent node by a splitting type, determine a depth of the current split node according to the splitting type, and compare the depth of the current split node with a maximum delta QP signaling depth. A video decoding system derives a delta QP from one or more syntax elements signaled in a TU associated with the current split node according to the comparing result, reconstructs a final QP for the current split node based on a reference QP and the delta QP, and decodes one or more TUs associated with the current split node using the final QP. The depth is counted in a way considering different splitting types and splitting partitions.

  • Patent number: 12063387
    Abstract: The techniques described herein relate to methods, apparatus, and computer readable media configured to determine motion vectors. The techniques relate to both encoders and decoders. For example, a decoder receives compressed video data related to a set of frames. The decoder calculates, using a decoder-side predictor refinement technique, a new motion vector for a current frame from the set of frames, wherein the new motion vector estimates motion for the current frame based on one or more reference frames. The calculation includes retrieving a first motion vector associated with the current frame, executing a first portion of the decoding process using the first motion vector, retrieving a second motion vector associated with the current frame that is different than the first motion vector, and executing a second portion of the decoding process using the second motion vector.

  • Patent number: 12047596
    Abstract: A method and apparatus of prediction for video coding are disclosed. According to one method, a block is partitioned into a first and second regions using a target partition selected from a partition set comprising triangle partition. A Merge candidate list is determined for a partitioned current block by including at least one HMVP (history-based motion vector prediction) candidate from an HMVP buffer, where the HMVP buffer stores motion information of previously coded blocks. The partitioned current block or current motion information associated with the partitioned current block are encoded or decoded using the Merge candidate list, where the Merge candidate list is used to derive a first candidate for the first region and a second candidate for the second region. In another method, whether to apply triangular CIIP (combined Inter/Intra prediction) to the current block is signaled at an encoder side or parsed at a decoder side.

  • Publication number: 20240236329
    Abstract: 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.

    Abstract: A method and apparatus for block partition are disclosed. If a cross-colour component prediction mode is allowed, the luma block and the chroma block are partitioned into one or more luma leaf blocks and chroma leaf blocks. If a cross-colour component prediction mode is allowed, whether to enable an LM (Linear Model) mode for a target chroma leaf block is determined based on a first split type applied to an ancestor chroma node of the target chroma leaf block and a second split type applied to a corresponding ancestor luma node. According to another method, after the luma block and the chroma block are partitioned using different partition tress, determine whether one or more exception conditions to allow an LM for a target chroma leaf block are satisfied when the chroma partition tree uses a different split type, a different partition direction, or both from the luma partition tree.
