  • Patent number: 12355996
    Abstract: A decoding method is disclosed. First, context for a syntax element associated with a current transform coefficient of a block of a picture is determined. The context is determined based on the area of said block, on the position of the current transform coefficient within the block and on the number of non-zero neighboring transform coefficients in a local template. Second, the syntax element is decoded based at least on the determined context. Advantageously, the local template depends on the shape of said block.

  • Publication number: 20250175639
    Abstract: Inferring an illumination compensation flag during encoding or decoding of a video image signal using frame rate up conversion can save one bit and eliminate complexity. The illumination compensation flag can be derived from the corresponding flags of at least one bi-predictive or bi-directional prediction candidates. The flag can also be derived from some function of the flags from those candidates. Alternatively, several flags can be used for respective coding or decoding of blocks if there are more than one prediction candidate using illumination compensation.

  • Patent number: 12273295
    Abstract: A receive (Rx) UE performs blind detection to decode a first-stage Sidelink Control Information (SCI) in a received signal. The first-stage SCI contains control information for the Rx UE to locate time-and-frequency resources used by a transmit (Tx) UE. The time-and-frequency resources are used to transmit the first-stage SCI and a second-stage SCI via a Physical Sidelink Control Channel (PSCCH) and to transmit data via a Physical Sidelink Shared Channel (PSSCH) associated with the PSCCH. The Rx UE locates the second-stage SCI in the time-and-frequency resources based on the first-stage SCI. The second-stage SCI contains additional control information from the Tx UE to the Rx UE for the sidelink V2X communication. The Rx UE decodes the second-stage SCI using at least in part an identifier which identifies the Rx UE as a destination of the received signal.

  • Publication number: 20250071280
    Abstract: Different quantization matrices may be transmitted corresponding to different block sizes, color components and prediction modes. To more efficiently signal the coefficients of the quantization matrices, in one implementation, a unified matrix identifier matrixId is used, based on a size identifier (sizeId) that relates to CU size with larger sizes listed first, and a matrix type (matrixTypeId) with luma QMs listed first. For example, the unified identifier is derived as: matrixId=N*sizeId+matrixTypeId, where N is the number of possible type identifiers, e.g., N=6. This single identifier allows referring to any previously transmitted matrix when using prediction (copy), and transmitting larger matrices first avoids interpolation in the prediction process. When a block uses the Intra Block Copy prediction mode, QM identifier may be derived as if the block uses the INTER prediction mode.

  • Patent number: 12238279
    Abstract: PROF (Prediction Refinement with Optical Flow) and BDOF (Bi-directional Optical Flow) use the optical flow model to provide sample-wise motion compensation refinement. In one implementation, to calculate the spatial gradients in BDOF, an extended region is generated around a block to be coded. To simplify the computation, BDOF may use the same padding operations as in PROF, namely, a padding sample is copied from the nearest integer neighbor in the reference picture. BDOF and PROF can also be used together when sub-block based affine motion-compensated prediction is used. BDOF can be applied after PROF generates new prediction blocks, or BDOF can use the spatial gradients in the original prediction blocks to re-use the computations with PROF. In addition, BDOF and PROF operations can be combined, and the prediction adjustment will be directly based on the spatial gradients in the original prediction blocks.
