Abstract

A three-dimensional data encoding method includes: calculating coefficient values from pieces of attribute information of three-dimensional points included in point cloud data; quantizing the coefficient values to generate quantization values; and generating a bitstream including the quantization values. The three-dimensional points corresponding to the coefficient values belong to one layer among one or more layers. Each of a predetermined number of layers among the one or more layers is assigned a quantization parameter for the layer. In the quantizing, (i) when a quantization parameter is assigned to a layer to which each of the coefficient values belongs, the coefficient value is quantized using the quantization parameter, and (ii) when the quantization parameter is not assigned to a layer to which each of the coefficient values belongs, the coefficient value is quantized using a quantization parameter assigned to one layer among the predetermined number of the layers.

Abstract

A server acquires a boarding point and an alighting point of each of a plurality of passengers riding together in a vehicle; calculates utility enjoyed by each of the plurality of passengers for a ridesharing service based on the boarding point and the alighting point of each passenger; calculates a total ridesharing fare for transportation through a route from a point where a first passenger, among the plurality of passengers, is picked up to a point where a last passenger is dropped off; and calculates, as a fare to be charged to each passenger, an amount obtained by distributing the total ridesharing fare to the plurality of passengers in accordance with a ratio of the utility of each of the plurality of passengers.

Abstract

An encoder includes circuitry and memory coupled to the circuitry. In operation, the circuitry: encodes a video using (i) a decoding parameter set (DPS) which is identified based on presence of the DPS in a bitstream and (ii) a sequence parameter set (SPS) which is identified based on an identifier for the SPS.

Abstract

The purpose of the present invention is to both suppress any decrease in data transmission efficiency in a device for transmitting data and suppress any decrease in received data quality in other devices. This communication device performs communication using a frequency band that is can be used in a wireless system, the communication device comprising a signal processing unit for generating a modulated signal, and a transmission unit for transmitting the modulated signal. The frequency band that can be used in the wireless system is configured from a plurality of channels. The transmission unit transmits the modulated signal using a first channel among the plurality of channels in a first time slot, and transmits the modulated signal using a second channel different from the first channel in a second time slot that follows the first time slot.
