Abstract: An authentication method is used by an automated driving system that includes a vehicle and an external device, the external device communicating with the vehicle to cause the vehicle to implement automated driving. The vehicle holds a first certificate that certifies validity of the vehicle. The external device holds a second certificate that certifies validity of the external device. The authentication method includes: validating a third certificate that certifies validity of a combination of the vehicle and the external device, in accordance with a result of device authentication performed between the vehicle and the external device by reference to the first certificate and the second certificate.

Abstract: An acoustic reproduction method includes: acquiring a first audio signal corresponding to an ambient sound that arrives at a listener from a first range in a sound reproduction space and a second audio signal corresponding to a target sound that arrives at the listener from a point in the sound reproduction space; acquiring direction information about the listener; performing, when a back range of the listener is determined to include the first range and the point based on the direction information, correction processing such that the first range does not overlap the point when the sound reproduction space is viewed in a predetermined direction; and mixing at least one of the first audio signal or the second audio signal and outputting the at least one thereof to an output channel.

Abstract: A video image encoding device, in a first mode, variable-length-encodes a residual coefficient to generate a coefficient code string, outputs the coefficient code string and the header information in a state in which the header information is associated with the coefficient code string, in a second mode, directly uses a differential image as a coefficient code string without variable-length-encoding the differential image, and outputs the coefficient code string and the header information in a state in which the header information is associated with the coefficient code string.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. In operation, the circuitry encodes, per temporal sub-layer, one or more hypothetical reference decoder (HRD) parameters into an HRD-related supplemental enhancement information (SEI) message, the one or more HRD parameters being one or more parameters for an HRD, the one or more parameters being related to a decoding unit, the HRD-related SEI message being an SEI message related to the HRD.

Abstract: 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.

Abstract: An encoder includes circuitry and memory. Using the memory, the circuitry performs a primary transform on a derived prediction error, performs a secondary transform on a result of the primary transform, quantizes a result of the secondary transform, and encodes a result of the quantization as data of an image. When a current block to be processed has a predetermined shape, the encoder performs the secondary transform using, among secondary transform basis candidates that are secondary bases usable in the secondary transform, only a secondary transform basis candidate having a size that is not largest size containable in the current block.

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.

Abstract: An image encoder writes a first parameter and a second parameter to a bitstream, and derives a partition mode based on the first and second parameters. Responsive to the derived partition mode being a first partition mode, the image encoder executes the first partition mode including: splitting a block of a picture into a plurality of first blocks including a N×2N block sized N pixels by 2N pixels; splitting the N×2N block, wherein a ternary split is allowed to split the N×2N block in a vertical direction, which is a direction along the 2N pixels, into a plurality of sub blocks including at least one sub block sized N/4×2N, while a binary split is not allowed to split the N×2N block in the vertical direction into two sub blocks that are equally sized N/2×2N; and encoding the plurality of sub blocks.
