Abstract: An encoder includes circuitry and memory coupled to the circuitry. The circuitry: assigns a picture level slice index and a subpicture level slice index to each of the slices, the picture level slice index being assigned at a picture level, the subpicture level slice index being assigned at a subpicture level; for each of the slices, encodes the subpicture level slice index of the slice into a slice header of the slice; and encodes each of the slices into a bitstream. The picture level slice index assigned to a current slice to be processed that is 10 included in a current subpicture to be processed is calculated by adding (i) the subpicture level slice index of the current slice and (ii) a total number of slices included in one or more subpictures that have been encoded prior to the current subpicture out of the subpictures.

Abstract: An image encoder includes: circuitry; and a memory coupled to the circuitry. The circuitry, in operation: calculates first values of a current block using intra prediction, the intra prediction being limited to planar mode, the planar mode using multiple reference pixels for each pixel location of the current block; calculates second values of the current block using inter prediction; calculates third values of the current block by weighting the first values and the second values; and encodes the current block using the third values, and in the calculating of the third values, a first weight is applied to the first values and a second weight is applied to the second values, the second weight being different from the first weight.

Abstract: A management system includes: a position sensor that obtains a positional relationship between itself and an object; a floor map generator that generates a floor map based on the position relationship; a self position calculator that calculates a self position; a marker identifier that identifies a marker; an asset information obtainer that obtains asset information related to an asset to which the marker is attached; an asset position calculator that calculates a position of the asset on the floor map based on the positional relationship, the self position, and a relative position of the marker; a database in which the floor map, the asset information, and the position information of the asset are associated with each other; and an asset management map generator that generates an asset management map based on the database.

Abstract: Provided is a method for transmitting a broadcasting content and a line content, the broadcasting content and the line content being synchronously displayed, the method including: generating a line parity packet from a plurality of line data packets in each of which the line content is stored; transmitting the line data packet and the line parity packet through a communication line; and transmitting a plurality of broadcasting data packets in each of which the broadcasting content is stored, from a base station using a broadcasting wave, a transfer clock time of the broadcasting content being delayed by a predetermined time compared with a transfer clock time of the line content. At this point, video quality can be improved when the real-time broadcasting program content and the real-time line content are simultaneously displayed.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. In operation, the circuitry: encodes information for deriving a parameter into a header of a bitstream; filters reconstructed samples in a first image using a filtering process, to generate a second image; determines whether the parameter has a predefined value; encodes a third image using the second image when the parameter has the predefined value; and encodes the third image using the first image when the parameter does not have the predefined value.

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.
