摘要： An encoder includes circuitry and memory coupled to the circuitry. The circuitry: executes a second process of applying a second filter to the first image to generate a second image, not holding the second image as a reference image, holding the first image as a reference image, and displaying the second image; writes coefficients of each of one or more filter candidates that are candidates for the second filter into a bitstream, wherein the coefficients are included in a first storage location when written into the bitstream; and writes a parameter that specifies, for each image, one of the one or more filter candidates as the second filter into the bitstream, wherein the parameter is included in a second storage location when written into the bitstream, and the second storage location is different from the first storage location.

摘要： Provided is an encoder including: circuitry; and memory coupled to the circuitry, in which the circuitry: derives a prediction residual indicating a difference between a current block and a prediction image of the current block; performs primary transform on the prediction residual, and performs secondary transform on a result of the primary transform; performs quantization on a result of the secondary transform; and encodes a result of the quantization. In the performing of the secondary transform, when a matrix weighted intra prediction included in intra prediction and having prediction modes is used, the circuitry uses, as a transform set for the secondary transform, a common transform set shared among the prediction modes. The matrix weighted intra prediction generates the prediction image by performing matrix calculation on a pixel sequence obtained from pixel values of surrounding pixels of the current block.

摘要： A multi-band communication device includes: one or more transceiver circuitries, each of which in operation transmits and receives data on a plurality of channels in different frequency bands; and a band configuration circuitry operative to change a configuration of any one of the transceiver circuitries based on configuration information received from a multi-band Access Point (AP). The configuration information specifies one of the frequency bands as a Primary band and the other frequency bands as Secondary band(s). The transceiver circuitry operating on the Primary band is used as a default circuitry for communication with the AP.

摘要： Various embodiments provide a decoder configured to select a filter based on a block size of a first block and a block size of a second block in an image, and change values of pixels in the first block and the second block. The filter includes a first set of multipliers and a first set of offsets for the first block, and a second set of multipliers and a second set of offsets for the second block. The values of the pixels in the first block and the second block are changed by performing multiplication with each multiplier in the first set of multipliers, by performing multiplication with each multiplier in the second set of multipliers, and by using the first set of offsets and the second set of offsets.

摘要： The present disclosure relates to a source base station. The source base station comprises a processing circuitry that generates a user equipment packet duplication status. The user equipment packet duplication status includes information on the status of uplink packet duplication performed by a user equipment with the source base station and at least one further base station. The information on the status of uplink packet duplication is per uplink radio bearer, one or more uplink radio bearers being established between the user equipment and the source base station. The source base station further comprises a transmitter that transmits the user equipment packet duplication status to a target base station which is the target of a handover from the source base station performed for the user equipment.

摘要： An encoder includes memory and circuitry. The circuitry: derives a first motion vector in a unit of a prediction block using a first inter frame prediction mode that uses a degree of matching between two reconstructed images of two regions in two difference pictures, the prediction block being obtained by splitting an image included in a video; and performs, in the unit of the prediction block, a first motion compensation process that generates a prediction image by referring to a spatial gradient of luminance in an image generated by performing motion compensation using the first motion vector derived.

摘要： An encoder includes circuitry and memory coupled to the circuitry. 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, generates a second coefficient value by applying an ALF (adaptive loop filtering) process to a second reconstructed image sample of a chroma component, and clips the second coefficient value. The circuitry generates a third coefficient value by adding the first coefficient value to the clipped second coefficient value, and clips the third coefficient value. The circuitry encodes a third reconstructed image sample of the chroma component using the clipped third coefficient value.
