    Abstract: An encoder that encodes a picture to generate a coded stream includes: circuitry and a memory coupled to the circuitry. The circuitry performs, using the memory: generating a prediction image of a current block included in a current picture by referring to a first region included in a reference picture different from the current picture; operating a bi-directional optical flow process to correct the prediction image by referring to a second region included in the first region, and not operating the bi-directional optical flow process in response to the second region not being included in the first region; and encoding the current block based on the prediction image.

    Abstract: To improve throughput by reducing the resource used for transmitting a parameter relating to retransmission control and decreasing the overhead of retransmission control signaling. In a case where a retransmission control method is employed in consideration of adaptive MCS control in which the encoding rate can be changed, the scheduling section sets the MCS in accordance with CQI notified from the communication counterpart apparatus. When transmission data is encoded, the RV parameter bit-number setting section sets the number of bits used for signaling the RV parameter to decrease as the encoding rate of the first transmission is decreased and sets the RV parameter based on the number of bits. For example, in a case where the encoding rate R is R>2/3, two bits are set. In a case where the encoding rate 1/3

    Abstract: Provided is an encoder includes: circuitry; and memory, in which the circuitry: determines which mode is used to perform a prediction process, among modes including a first mode in which the prediction process is performed based on a motion vector of each block in a video and a second mode in which the prediction process is performed based on a motion vector of each sub-block obtained by splitting the block; when the prediction process is performed in the first mode, determines whether to perform a correction process on a prediction image using a spatial gradient of pixel values in the prediction image obtained by performing the prediction process, and performs the correction process when it is determined to perform the correction process; and when the prediction process is performed in the second mode, does not perform the correction process.

    Abstract: Various embodiments for controlling a state of an autonomous vehicle that is to meet a user are provided. A receiver receives location information indicating a current location of the user. A memory stores a plurality of states of the autonomous vehicle. Each of the states at least one of visually or audibly distinguishes the autonomous vehicle. A sensor senses an environment of the autonomous vehicle to obtain environment information. A distance from a place of meeting the user to the current location of the user is calculated based on the location information. A first state is selected in accordance with the environment information. The autonomous vehicle is caused to change from a second state to the first state when the distance from the place of meeting the user to the current location of the user becomes smaller than or equal to a predetermined distance.
