  • Publication number: 20220303564
    Abstract: An encoder includes circuitry and memory coupled to the circuitry. In operation, the circuitry writes, into a bitstream, a first flag indicating whether or not to enable a first process of applying a filter to a first image to generate a second image, holding the second image as a reference image, and displaying the second image. When the first process is not enabled, circuitry writes, into the bitstream, one or more parameters for controlling a second process of applying the filter to the first image to generate the second image, holding the first image as a reference image, and displaying the second image.

  • Publication number: 20220272334
    Abstract: An encoder includes circuitry and memory. The circuitry, in operation, generates a first coefficient value by applying a CCALF (cross component adaptive loop filtering) process to a first reconstructed image sample of a luma component. The circuitry generates a second coefficient value by applying an ALF (adaptive loop filtering) process to a second reconstructed image sample of a chroma component. The circuitry generates a third coefficient value by adding the first coefficient value to the second coefficient value, and encodes a third reconstructed image sample of the chroma component using the third coefficient value. In the CCALF process, in response to a coordinate of the second reconstructed image sample being (x, y), coordinates of the first reconstructed image samples are (2x, 2y?1), (2x?1, 2y), (2x, 2y), (2x+1, 2y), (2x?1, 2y+1), (2x, 2y+1), (2x+1, 2y+1), and (2x, 2y+2).

  • Patent number: 11425385
    Abstract: An encoder includes circuitry and memory coupled to the circuitry. The circuitry, in operation, for each coefficient of a plurality of coefficients included in a block, determines a base level relating to Context-Based Adaptive Binary Arithmetic Coding (CABAC) for the coefficient, and encodes an absolute value of the coefficient. In determining the base level, when one or more flags are used in encoding the absolute value of the coefficient, the base level is determined to be a first value, and when one or more flags are not used in the encoding, the base level is determined to be a second value that is smaller than the first value. In encoding the absolute value of the coefficient, when one or more flags are not used, a rice parameter is determined based on the base level which is equal to the second value, and the coefficient is binarized using the rice parameter.

    Abstract: An encoder includes circuitry and memory coupled to the circuitry. The circuitry determines whether to split a current luma virtual pipeline decoding unit (VPDU) into smaller blocks. When it is determined not to split the current luma VPDU into smaller blocks, the circuitry predicts a block of chroma samples without using luma samples. When it is determined to split the luma VPDU into smaller blocks, the circuitry predicts the block of chroma samples using luma samples. The circuitry encodes the block using the predicted chroma samples.
