Classification: CPC H | IPC H

Claim 0:
1. An encoder that encodes a video, the encoder comprising:
circuitry; and
memory,
wherein, using the memory, the circuitry:
generates a motion vector predictor list by registering motion vectors obtained by referencing a plurality of encoded blocks, selects one motion vector predictor from the motion vector predictor list, and implements a prediction mode that performs motion compensation on a current block using a motion vector derived from the one motion vector predictor,

the motion vector predictor list includes (i) a first motion vector predictor obtained from a block in a first range that spatially neighbors the current block, and (ii) a second motion vector predictor obtained from a block positioned at any of a plurality of predetermined positions in a second range that is broader than the first range,
information on motion vectors to be referenced in the prediction mode is managed in association with reference blocks of a specific size, and
the plurality of predetermined positions are positions of reference blocks in positions defined by a regular interval using a current picture including the current block as a reference.
