Abstract: An encoder which encodes a video including a plurality of pictures includes circuitry and memory. Using the memory, the circuitry performs: encoding a first picture among the plurality of pictures; and performing (i) a first operation for encoding a parameter set for a second picture which follows the first picture in coding order among the plurality of pictures after encoding the first picture, and encoding the second picture after encoding the parameter set, or (ii) a second operation for encoding the second picture without encoding the parameter set after encoding the first picture. The circuitry performs the first operation when the second picture is a determined picture, in the performing of the first operation or the second operation.

Abstract: In an operation in a license-exempt band (unlicensed band), the present invention contributes to the provision of a mobile station, a base station, a transmission method and a receiving method which suitably transmit and receive a signal. The mobile station 200 includes: a transmission unit 205 which transmits an uplink signal; and a control unit 201 which, when a first number indicating a first resource amount that can be used in the transmission of the uplink signal includes a third number, which is different from a specific second number, as a prime factor, controls the transmission of a signal of a fourth number that does not include the third number as the prime factor by using a second resource.

Abstract: An encoder comprises: a processor; and memory coupled to the processor, in which in operation, the processor: generates a first prediction image having full-pel precision, based on a motion vector of the current block; generates a second prediction image having fraction-pel precision by interpolating a value at a fraction-pel position between full-pel positions included in the first prediction image, using a first interpolation filter or a second interpolation filter differing in a total number of taps from the first interpolation filter; and encodes the current block based on the second prediction image, and in the generating of the second prediction image, the processor switches between using the first interpolation filter and the second interpolation filter depending on whether an affine mode is used for the current block.

Abstract: An encoder includes circuitry and memory. The circuitry, using the memory: prohibits a first splitting method when arrangement and shapes of blocks obtained by splitting a first block multiple times by the first splitting method are identical to arrangement and shapes of blocks obtained by splitting the first block multiple times by a second splitting method different from the first splitting method, and when scan order of the blocks obtained by the first splitting method is identical to scan order of the blocks obtained by the second splitting method; and encodes the first block.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. The circuitry, in operation: partitions a block of a current image to be encoded into a plurality of partitions including a first partition and a second partition that are adjacent to each other; performs orthogonal transform only on the first partition out of the first partition and the second partition; and applies a deblocking filter to a boundary between the first partition and the second partition.

Abstract: An anomalous vehicle detection server includes an anomaly score calculator that detects a suspicious behavior different from a predetermined driving behavior based on pieces of vehicle information that are received from a plurality of vehicles, respectively, and are each based on a vehicle log including the content of an event that has occurred in a vehicle system provided in the vehicle, and acquires an anomaly score of each of the plurality of vehicles that indicates a likelihood that reverse engineering is performed on the vehicle; and an anomalous vehicle determiner that determines whether one vehicle of the plurality of vehicles is an anomalous vehicle based on the anomaly score of the one vehicle and a statistical value of the anomaly scores of two or more vehicles of the plurality of vehicles.

Abstract: In a transmission device, a signal processing circuit generates an aggregate physical layer convergence protocol data unit (A-PPDU) by adding a guard interval to each of a first part of a first physical layer convergence protocol data unit (PPDU) transmitted over each of a first through L'th channel of a predetermined channel bandwidth, where L is an integer of 2 or greater, a second part of the first PPDU transmitted over each of an (L+1)'th through P'th channel, which is a variable channel bandwidth that is N times the predetermined channel bandwidth, where N is an integer of 2 or greater and P is an integer of L+1 or greater, and a second PPDU transmitted over the (L+1)'th through P'th channel. A wireless circuit transmits the A-PPDU.
