Abstract:
1. A moving picture decoding method for performing inter prediction decoding on a decoding target block included in a decoding target picture, the moving picture decoding method comprising: obtaining a temporal motion vector enable flag which indicates whether or not using a temporal motion vector predictor is enabled, the temporal motion vector predictor being from a block which is included in a decoded picture different from the decoding target picture and which corresponds to the decoding target block; generating a plurality of motion vector predictors; decoding a motion vector using one of the plurality of motion vector predictors generated in the generating; and decoding the decoding target block using the motion vector decoded in the decoding of the motion vector, wherein, in the generating, a motion vector having a motion quantity of 0 is generated when the temporal motion vector enable flag indicates that using the temporal motion vector predictor is not enabled, the motion vector being included, as a replacement vector which replaces the temporal motion vector predictor, in the plurality of motion vector predictors.
