MOVING PICTURE DECODING DEVICE, MOVING PICTURE DECODING METHOD AND MOVING PICTURE DECODING PROGRAM, AND RECEIVING DEVICE, RECEIVING METHOD AND RECEIVING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a moving picture coding and moving picture decoding technology capable of efficiently achieving parallel processing of motion compensation prediction that performs motion compensation prediction collectively on a plurality of neighboring prediction blocks.SOLUTION: A merging motion information candidate generation unit 230 derives, when information indicating whether or not to derive a merging motion information candidate shared for all prediction blocks in a decoding block is information indicating the derivation of a merging motion information candidate shared for all the prediction blocks in the decoding block, a plurality of merging motion information candidates shared for all the prediction blocks in the decoding block. A merging motion information selection unit 231 selects one merging motion information candidate from among the plurality of merging motion information candidates on the basis of a candidate specifying index, and uses the selected merging motion information candidate in the prediction block subject to decoding.SELECTED DRAWING: Figure 22
