Abstract: A method for controlling rights of an autonomous vehicle includes acquiring, via a network, identification information for identifying a user or a terminal of the user, and dispatching request information that indicates a dispatch request for the autonomous vehicle issued by the user. The method further includes selecting the autonomous vehicle to be dispatched to the user from among multiple autonomous vehicles based on the dispatch request information, and assigning a control right for the selected autonomous vehicle, to the user or the terminal, based on the identification information.

Abstract: An encoder includes memory and circuitry. The circuitry, using the memory, (i) selects a mode from among a plurality of modes each for deriving a motion vector, and derives a motion vector for a current block via the selected mode, and (ii) performs inter prediction encoding on the current block, using the derived motion vector, via one of a skip mode and a non-skip mode different from the skip mode. The plurality of modes include a plurality of first modes each for predicting the motion vector for the current block based on an encoded block neighboring the current block without encoding information indicating a motion vector into a stream. When a second mode included in the plurality of first modes is selected, the current block is encoded via the non-skip mode regardless of presence or absence of a residual coefficient.

Abstract: An encoding method includes: changing values of luma pixels in a first block and a second block to filter a first boundary between the first block and the second block, using clipping such that change amounts of the respective values are within respective luma clip widths, the luma pixels in the first block and the second block being arranged along a first line across the first boundary; and changing values of chroma pixels in a third block and a fourth block to filter a second boundary between the third block and the fourth block, using clipping such that change amounts of the respective values are within respective chroma clip widths, the chroma pixels in the third block and the fourth block being arranged along a second line across the second boundary. The luma clip widths applied to the luma pixels are selected to be asymmetrical relative to the first boundary.

Abstract: A transmitter includes a mapping circuit and a framing circuit. The mapping circuit is configured to combine and map a first data sequence and a second data sequence onto orthogonal frequency division multiplexing (OFDM) subcarriers which include first subcarriers and second subcarriers. The framing circuit is configured to generate an OFDM signal from the OFDM subcarriers. The mapping circuit is configured to: map first data included in the first data sequence and second data included in the second data sequence onto the first subcarriers; and map the second data onto the second subcarriers. The first data are not mapped on the second subcarriers.

Abstract: An information processing method includes processing of: acquiring, from a plurality of time-series images in which an object is captured, first information including at least a plurality of positions or a plurality of sizes of the object; executing prediction processing of predicting second information including at least one of a position or a size of the object at a next time point in a time-series based on the first information and recursively executing the prediction processing based on the first information and the second information to predict the second information of the object at a time point further next to the next time point; executing recognition processing of recognizing motion of the object based on the second information; and determining a total number of times of recursion of the prediction processing based on a result of the recognition processing.

Abstract: An image encoder performs a first partitioning including using a first partition mode, without writing first splitting information indicative of the first partition mode into a bitstream, to split a first block into a plurality of second blocks in response to that the first block is located adjacent to an edge of a picture and that the dimensions of the first block satisfy a first condition; and performs a second partitioning on the second block by writing second splitting information indicative of a second partition mode into the bitstream, wherein the second partition mode allows at least one of a quad tree splitting and a binary splitting, and using the second partition mode to split the second block into a plurality of coding units (CUs), wherein the second partition mode prohibits the quad tree splitting of the second block in certain conditions.

Abstract: A service server generates a first smart contract programmed to be capable of executing provision of an incentive to a user when a goal indicated by generated challenge content generated is achieved, generates first transaction data including the first smart contract, and transmits the data to a first authentication server. The first authentication server executes a consensus algorithm and records the first transaction data in a distributed ledger to run the first smart contract. The first authentication server notifies a device used by the user of the challenge content. The first authentication server obtains, from the device, second transaction data including first challenge content selected to be registered by the user, and records the second transaction data in the distributed ledger by executing a consensus algorithm.

Abstract: A communication apparatus of the present disclosure comprises a first receiver which, in operation, receives a downlink data frame from a base station; a decoder which, in operation, decodes data included in the received downlink data frame; a signal generator which, when the decoded data indicates that there is no buffered traffic for the communication apparatus, generates an uplink frame that includes acknowledgement information and a wake-up radio (WUR) mode request indicating a request to transit to the WUR mode from a primary connectivity radio (PCR) mode; and a transmitter which, in operation, transmits the uplink frame to the base station.
