Abstract:
A predicted signal generation unit provided in a video predictive encoding device estimates a zero-th motion vector for derivation of a zero-th predicted signal, selects a zero-th motion vector predictor similar to the zero-th motion vector, and generates zero-th side information containing a zero-th motion vector predictor index to identify the motion vector predictor and a motion vector difference determined from the zero-th motion vector and the zero-th motion vector predictor. The video predictive encoding device selects a motion vector for generation of a first predicted signal having a high correlation with a target region, generates first side information containing a first motion vector predictor index to identify the motion vector as a first motion vector predictor, sets the first motion vector predictor to a first motion vector, and combines the zero-th and first predicted signals to generate a predicted signal of the target region.
