Abstract: An encoder includes circuitry and memory. In both of a first type of residual coding where an orthogonal transform is applied and a second type of residual coding where the orthogonal transform is skipped, wherein when a restriction on a number of CABAC processes allows CABAC coding of a set of coefficient information flags, the circuitry: encodes the coefficient information flags by CABAC; and otherwise, the circuitry: skips the CABAC encoding of the coefficient information flags; and the circuitry encodes a remainder value of the coefficient with Golomb-Rice code when the coefficient information flags are encoded; and otherwise the circuitry encodes a value of the coefficient with the Golomb-Rice code, wherein in the second type of residual coding, the circuitry encodes absolute value flags each relating to an absolute value of the coefficient after encoding the coefficient information flags and before encoding the remainder value of the coefficient.

Abstract: An encoder includes circuitry and memory connected to the circuitry. In operation, the circuitry: derives a correction parameter using only a neighboring reconstructed image that neighbors a processing unit which has a determined size and is located at an upper left of a current block to be processed in an image, among neighboring reconstructed images that neighbor the current block, and performs correction processing of the current block based on the correction parameter derived, when the current block has a size larger than the determined size.

Abstract: This encoding device comprises: a downmix circuit that switches mixing processing according to the characteristic of an input stereo signal to generate either a first stereo signal or a second stereo signal obtained by mixing processing of a left channel signal and a right channel signal; a first encoding circuit that encodes the first stereo signal; and a second encoding circuit that encodes two signals included in the second stereo signal. The second encoding circuit performs monaural encoding on the basis of the encoding mode of the first encoding circuit in a first section in which switching from the first stereo signal to the second stereo signal is performed and/or a second section in which switching from the second stereo signal to the first stereo signal is performed.

Abstract: An encoder determines, based on a width and a height of a block, whether or not to disable a prediction mode in which the block is split along a partitioning line defined by a distance and an angle and then prediction is performed; and encodes the block with the prediction mode disabled or not disabled according to a result of the determination on whether or not to disable the prediction mode. Here, the distance is the shortest distance between the center of the block and the partitioning line, and the angle is an angle representing a direction from the center of the block toward the partitioning line in the shortest distance. The encoder determines to disable the prediction mode when (i) a width-to-height ratio is at least 8 or (ii) a height-to-width ratio is at least 8.

Abstract: A transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate performance that otherwise would be caused by fading or the like. There are included encoding parts that encode transport data; a mapping part that performs such a mapping that encoded data sequentially formed by the encoding parts are not successively included in the same symbol, thereby forming data symbols; and a symbol interleaver that interleaves the data symbols. In this way, a low computational complexity can be used to perform an interleaving process equivalent to a bit interleaving process to effectively improve the reception quality at a receiving end.

Abstract: The present disclosure relates to a resource allocation procedure, performed between a user equipment and radio base station. The UE is configured with at least one numerology scheme, each associated with parameters partitioning time-frequency radio resources into resource scheduling units differently. The UE is configured with logical channels each of which is associated with at least one numerology scheme. A receiver of the UE receives from the radio base station an uplink scheduling assignment, which indicates uplink radio resources usable by the UE. A processor of the UE determines for which numerology scheme the received uplink scheduling assignment is intended based on the received uplink scheduling assignment. The processor performs a logical channel prioritization procedure by allocating the assigned uplink radio resources to the configured logical channels and by prioritizing those logical channels that are associated with the numerology scheme for which the uplink scheduling assignment is intended.

Abstract: In an anomaly detection method that determines whether each frame in observation data constituted by a collection of frames sent and received over a communication network system is anomalous, a difference between a data distribution of a feature amount extracted from the frame in the observation data and a data distribution for a collection of frames sent and received over the communication network system, obtained at a different timing from the observation data, is calculated. A frame having a feature amount for which the difference is predetermined value or higher is determined to be an anomalous frame. An anomaly contribution level of feature amounts extracted from the frame determined to be an anomalous frame is calculated, and an anomalous payload part, which is at least one part of the payload corresponding to the feature amount for which the anomaly contribution level is at least the predetermined value, is output.
