  • Patent number: 12294695
    Abstract: A method of encoding a motion information predictor index, comprising: generating a list of motion information predictor candidates; when an Affine Merge mode is used, selecting one of the motion information predictor candidates in the list as an Affine Merge mode predictor; when a non-Affine Merge mode is used, selecting one of the motion information predictor candidates in the list as a non-Affine Merge mode predictor; and generating a motion information predictor index for the selected motion information predictor candidate using CABAC coding, one or more bits of the motion information predictor index being bypass CABAC coded.

  • Publication number: 20250097412
    Abstract: A method of filtering an image is disclosed, the method comprising: receiving filter coefficients and first component sample values corresponding to samples surrounding a reference sample, and inputting said filter coefficients and first component sample values into a cross component filter to produce a cross component filter output; wherein said cross-component filter uses a restricted number of bits to represent said filter coefficients and/or first component sample values to produce said filter output.
