Abstract: The interleaver 104 interleaves first to Nth code words. The OFDM modulation circuit 105 converts the interleaved first to Nth code words into OFDM signals. The transmission RF circuit 106 transmits the OFDM signals. The number of data symbols included in the first code word is less than the number of data symbols included in the second code word. The interleaver 104 writes the first code word to the Nth code word in ascending order and starts reading from the second code word.

Abstract: An encoder includes memory and circuitry configured to determine a merge mode to be applied to a current block, wherein the merge mode includes a sub-block merge mode and a first merge mode. In the merge mode, inter-prediction parameters are inferred from a neighboring block neighboring the current block. In the sub-block merge mode, the current block includes a plurality of sub-blocks, and inter-prediction parameters are provided for each of the plurality of sub-blocks. When the merge mode is determined to be the first merge mode, the circuitry generates a prediction image for the current block by performing a bi-directional optical flow prediction process, wherein the bi-directional optical flow prediction process uses a spatial gradient for the current block. When the merge mode is determined to be the sub-block merge mode, the circuitry generates a prediction image for the current block by not performing the bi-directional optical flow prediction process.

Abstract: A decoder includes circuitry which, in operation, parses a first flag indicating whether a CCALF (cross component adaptive loop filtering) process is enabled for a first block located adjacent to a left side of a current block; parses a second flag indicating whether the CCALF process is enabled for a second block located adjacent to an upper side of the current block; determines a first index associated with a color component of the current block; and derives a second index indicating a context model, using the first flag, the second flag, and the first index. The circuitry, in operation, performs entropy decoding of a third flag indicating whether the CCALF process is enabled for the current block, using the context model indicated by the second index; and performs the CCALF process on the current block in response to the third flag indicating the CCALF process is enabled for the current block.

Abstract: Provided is a network monitor for a mobility network used in a mobility entity. The mobility network is formed of a source unit, a destination unit, and one or more repeaters. Each repeater includes a network monitor that receives, from the source unit, an announcement for a bandwidth reservation. The announcement includes a value of a first bandwidth requirement for the source unit to perform first data communication. The network monitor further determines a determination result of whether to reserve the first bandwidth by comparing the value of the first bandwidth with a range of values of a second bandwidth for the first data communication specified in a white list stored in a database. The network monitor reserves the first bandwidth for performing the first data communication depending on the determination result, and transmits, to the source unit, a reservation status of the first bandwidth.

Abstract: A communication apparatus includes a circuitry and a transmitter. In operation, the circuitry generates a Demodulation Reference Signal (DMRS) and generates downlink control information indicating a mapping pattern of the DMRS from a plurality of mapping patterns, and the transmitter transmits the DMRS and the downlink control information. The plurality of mapping patterns includes a first mapping pattern and a second mapping pattern. Resource elements used for the DMRS of the second mapping pattern are same as a part of resource elements used for the DMRS of the first mapping pattern. A number of the resource elements used for the DMRS of the first mapping pattern is larger than a number of the resource elements used for the DMRS of the second mapping pattern.

Abstract: An encoder capable of properly handling an image to be encoded or decoded includes processing circuitry and memory connected to the processing circuitry. Using the memory, the processing circuitry: obtains parameters including at least one of (i) one or more parameters related to a first process for correcting distortion in an image captured with a wide angle lens and (ii) one or more parameters related to a second process for stitching a plurality of images; generates an encoded image by encoding a current image to be processed that is based on the image or the plurality of images; and writes the parameters into a bitstream including the encoded image.

Abstract: A video decoding device, in the case where a video of the progressive format is inputted, processes a frame as a picture, in the case where a video of the interlace format is inputted, processes a field as a picture. A video decoding device performs display control corresponding to a format of the both video by analyzing display control information in display control information analyzer. The display control information includes sequence unit display control information which is commonly used in a display process of all pictures that belong to a sequence to be decoded and picture unit display control information which is individually used in a display process of a picture to be decoded. A second code string analyzer acquires each of the sequence unit display control information and the picture unit display control information from an extended information area in units of pictures.
