Abstract: A decoding system decodes a video stream, which is encoded video information. The decoding system includes a decoder that acquires the video steam and generates decoded video information, and a maximum luminance information acquirer that acquires, in a case where a dynamic range of luminance of the video stream is a second dynamic range that is wider than a first dynamic range, maximum luminance information indicating the maximum luminance of the video stream from the video stream. The decoding system also includes an outputter that outputs the decoded video information and the maximum luminance information. Where the dynamic range of luminance of the video stream is expressed by the maximum luminance of all pictures in the video stream as the maximum luminance information, the outputter outputs the decoded video information, along with the maximum luminance information indicating the maximum luminance of all pictures in the video stream.

Abstract: The present disclosure relates to a user equipment in a mobile communication system. The UE comprises processing circuitry, which determines whether the UE, being located in a first radio access network notification area, first RNA, is moving to a second radio access network notification area, second RNA, different from the first RNA. The UE is in an inactive state out of an idle state, a connected state and the inactive state the user equipment can be in. The UE further comprises a transmitter, which transmits identification information on the first RNA to a second radio base station of the second RNA, when determining that the UE is moving to the second RNA. The UE further comprises a receiver which receives from the second radio base station UE related context information usable by the UE to exchange uplink and downlink data with the second radio base station.

Abstract: An information processing method is executed by a computer and includes: obtaining a third model in which a first model which is a machine learning model that performs a deblurring process of an input image and outputs a feature quantity and a second model which is a machine learning model that performs an object recognition process of the input image and outputs a result of the object recognition are connected so that an output of the first model becomes an input of the second model; training the third model through machine learning so that a difference between a result of object recognition that is output from the third model after a training image with blur is input into the third model and reference data relating to the result of the object recognition corresponding to the training image decreases; and outputting the third model which has undergone the training.

Abstract: When a management device receives battery exchange demand information from a first vehicle, the management device specifies at least one exchange partner candidate which is a vehicle providing a battery exchange with the first vehicle, transmits battery exchange request information to the exchange partner candidate, specifies, when receiving a battery exchange acceptance signal from a second vehicle, a battery exchange place based on location information about each of the first vehicle and the second vehicle, creates exchange instruction information including position information about the battery exchange place, and transmits the exchange instruction information to the first vehicle and the second vehicle.

Abstract: Various embodiments provide an encoder that performs an up-conversion and a down-conversion on a first quantization matrix to generate a second quantization matrix, and quantizes transform coefficients of a current block using the second quantization matrix. The first quantization matrix has a first number of rows and a first number of columns equal to the first number of rows, and the second quantization matrix has a second number of rows and a second number of columns different from the second number of rows. In the up-conversion, the circuitry generates the second quantization matrix such that one of the second number of rows or the second number of columns is larger than the first number of rows. In the down-conversion, the circuitry generates the second quantization matrix such that the other of the second number of rows or the second number of columns is smaller than the first number of rows.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. The circuitry: executes a second process of applying a second filter to the first image to generate a second image, not holding the second image as a reference image, holding the first image as a reference image, and displaying the second image; writes coefficients of each of one or more filter candidates that are candidates for the second filter into a bitstream, wherein the coefficients are included in a first storage location when written into the bitstream; and writes a parameter that specifies, for each image, one of the one or more filter candidates as the second filter into the bitstream, wherein the parameter is included in a second storage location when written into the bitstream, and the second storage location is different from the first storage location.

Abstract: According to the present invention, a base station can dynamically change a repetition transmission method as appropriate. In a base station (100), a repetition control unit (103) determines a data repetition pattern for a terminal (200). A transmission unit (109) repeatedly transmits data (repetition transmission) on the basis of the repetition pattern. The data repetition pattern corresponds to control information to be reported to the terminal (200) by dynamic signaling.

Abstract: An indicator in a master AP from among a plurality of APs obtains communication quality of communication with an AP which is a communication partner. In the case where the obtained communication quality is less than a threshold, the indicator causes the plurality of APs including the master AP to perform cooperative operation to transmit data. In the case where the obtained communication quality is not less than the threshold, the indicator causes the plurality of APs including the master AP to stop the cooperative operation.
