Abstract: In a transmission method according to one aspect of the present disclosure, a encoder performs error correction coding on an information bit string to generate a code word. A mapper modulates a first bit string in which the number of bits is the predetermined integral multiple of (X+Y) in the code word using a first scheme, the first scheme being a set of a modulation scheme in which an X-bit bit string is mapped to generate a first complex signal and a modulation scheme in which a Y-bit bit string is mapped to generate a second complex signal, and modulates a second bit string in which the first bit string is removed from the code word using a second scheme different from the first scheme.

Abstract: A three-dimensional data encoding method includes: selecting, as one or more candidates for calculating a predicted value of attribute information of a first three-dimensional point, one or more three-dimensional points from a plurality of three-dimensional points, the one or more three-dimensional points being closest to the first three-dimensional point; calculating a predicted value using pieces of attribute information of the one or more three-dimensional points selected as the one or more candidates; calculating a prediction residual that is a difference between the attribute information of the first three-dimensional point and the predicted value calculated; and generating a bitstream, based on the prediction residual. In the selecting, when the plurality of three-dimensional points include three-dimensional points equidistant from the first three-dimensional point, the one or more candidates are selected based on a first Morton code of the first three-dimensional point.

Abstract: A speaker recognition device acquires a registered voice, converts the acquired registered voice to a plurality of property converted voices having respective acoustic properties different from each other, extracts a speaker feature indicative of a characteristic of a speaker from the registered voice, extracts a speaker feature from each of the property converted voices, compares all pairs of speaker features of a part or all of the speaker feature extracted from the registered voice and the speaker features extracted from the property converted voices, and calculates a threshold used for recognition of a speaker of an input voice on the basis of a result of the comparison.

Abstract: An encoder includes: circuitry; and memory coupled to the circuitry. The circuitry, in operation, stores a first parameter into a bitstream, the first parameter indicating, as a prediction mode, one of (i) a multiple prediction mode in which a prediction image is generated by overlapping an inter prediction image of a current block and an intra prediction image of the current block and (ii) one of a plurality of prediction modes including a non-rectangular mode in which a prediction image is generated for each non-rectangular partition in the current block, and encodes the current block according to the prediction mode.

Abstract: A transmission device includes a generator that generates a frame in a predetermined frame format and a communicator that transmits the frame generated by the generator. The predetermined frame format includes a first field indicating whether information related to a wake-up process performed by a device that received a frame in the predetermined frame format is valid or not. When the first field indicates that the information is valid, the predetermined frame format further includes a second field indicating identification information identifying the device.

Abstract: A three-dimensional data encoding method includes generating a bitstream by encoding subspaces included in a current space including three-dimensional points. In the generating of the bitstream: first information is stored in a first header which is common to the subspaces and included in the bitstream, the first information indicating first coordinates which are coordinates of the current space; and second information is stored in a second header which is provided on a subspace basis and included in the bitstream, the second information indicating a difference between second coordinates which are coordinates of a corresponding subspace among the subspaces and the first coordinates.
