The circuitry, in operation: determines whether a size of a current block, which is a unit for which a vector candidate list including vector candidates is generated, is less than or equal to a threshold; when the size of the current block is less than or equal to the threshold, generates the vector candidate list by registering a history-based motion vector predictor (HMVP) vector candidate in the vector candidate list from an HMVP table without performing a first pruning process; when the size of the current block is greater than the threshold, generates the vector candidate list by performing the first pruning process and registering the HMVP vector candidate in the vector candidate list from the HMVP table; and encodes the current block using the vector candidate list.

Abstract

A base station is disclosed, which is capable of appropriately configuring the timings of data assignment, data transmission and reception, and feedback for a case where the DL and UL sTTI lengths are different from each other. In this base station (100), a transmission section (106) transmits a downlink signal using a first short transmission time interval (sTTI) shortened in length than a TTI and used for downlink; and a reception section (107) receives an uplink signal using a second sTTI shortened in length than the TTI and used for uplink. When the first sTTI is shorter in length than the second sTTI, the reception section (107) receives the uplink signal in the second sTTI positioned after a predetermined interval from the transmission timing of the downlink signal, the predetermined interval being configured based on the length of the first sTTI.

Abstract

An encoder includes circuitry and a memory coupled to the circuitry. The circuitry, in operation, determines whether or not a ternary split process of splitting a block into three sub blocks in a first direction parallel to a first longer side of the block is allowed by comparing a size of a second shorter side of the block to a minimum threshold value. The circuitry, responsive to the ternary split process being allowed, writes, into a bitstream, a split direction parameter indicative of a splitting direction. The circuitry, in operation, splits the block into a plurality of sub blocks in a direction indicated by the split direction parameter; and encodes the plurality of sub blocks. The minimum threshold value corresponds to a minimum size supported in a transform process.

Abstract

A work support method, for supporting work performed by multiple users including a target user on an object in a virtual space where the object is placed, includes obtaining first information including at least one of sound information, input information, or schedule information; obtaining second information indicating manipulation of the object by the target user; determining whether the manipulation by the target user is to be applied to one or more other users among the multiple users based on the first information; generating images each viewed by a corresponding one of the one or more other users based on the result of the determining and the second information; and outputting the generated images to terminals of the one or more other users.
