  • Patent number: 11930200
    Abstract: An apparatus for video decoding, includes processing circuitry configured to determine an affine model for a current block coded with an interweaved affine mode. Based on the affine model, a first prediction block corresponding to a first pattern for partitioning the current block into first sub-blocks and a second prediction block corresponding to a second pattern for partitioning the current block into second sub-blocks can be generated. The first and second prediction blocks include interpolated samples having an intermediate bit-depth larger than an input bit-depth of the current block. Co-located first and samples in the first and second prediction blocks with a precision corresponding to the intermediate bit-depth are weighted averaged to obtain averaged samples. The averaged samples are rounded to the input bit-depth to obtain corresponding third samples in a final prediction block of the current block.

  • Patent number: 11895326
    Abstract: Frames from an image stream or streams are processed by independently operating digital signal processors (DSPs), with only frame checking microprocessors operating in a lockstep mode. In one example, two DSP are operating on alternate frames. Each DSP processes the frames and produces prediction values for the next frame. The lockstep microprocessors develop their own next frame prediction. The lockstep processors compare issued frames and previously developed predicted frames for consistency. If the predictions are close enough, the issued frame passes the test. The lockstep processors then compare the issued frame to the preceding two frames for a similar consistency check. If the prior frames are also close enough, the issued frame is acceptable. In another example, hardware checkers are provided to compare the present frame with a larger number of prior frames. The hardware checkers provide comparison results to the lockstep processors to compare against allowable variation limits.

  • Patent number: 11889099
    Abstract: Exemplary video processing methods and apparatuses for encoding or decoding a current block by bi-directional prediction are disclosed. L0 and L1 reference blocks are determined for the current block, and a motion vector refinement is applied to refine the L0 and L1 reference blocks using a motion estimation search performed on each processing unit in the current block. A bi-directional optical flow operation is early terminated according to a cost of each processing unit in the current block. The processing units for cost calculation in the motion vector refinement and the bi-directional optical flow early termination are unified. The bi-directional optical flow operation is applied to the current block to further refine the L0 and L1 reference blocks if the bi-directional optical flow operation is not early terminated. A final inter predictor is derived from the refined L0 and L1 reference blocks for encoding or decoding the current block.
