Abstract:
A video prediction encoding device provided with a picture storage unit storing, as reference pictures to be used for encoding of a subsequent picture, one or more of reconstructed pictures restored from compressed picture data and a memory control unit to control a frame memory in the picture storage unit. When a frame size of input pictures is not more than 1/(2̂L) (where L is an integer of one or more) of a maximum frame size of pictures, the memory control unit determines that (2̂L) times the maximum number of reconstructed pictures are storable in the frame memory.

Claim (Index 1):
A video predictive decoding method executed by a video predictive decoding device, comprising:\n an input step of inputting encoded data comprising compressed picture data which includes a target picture frame size, a maximum number of storable reconstructed pictures, and a maximum frame size specified as an encoding constraint, wherein a plurality of pictures forming a video sequence are encoded by either intra-frame prediction or inter-frame prediction; a decoding step of decoding the compressed picture data and the compressed picture data constituting the information on the target picture frame size, the maximum number of storable reconstructed pictures, and the maximum frame size to reproduce pictures and the information on the target picture frame size, the maximum number of storable reconstructed pictures, and the maximum frame size; and a picture storage step of storing in picture storage means one or more of the reconstructed pictures as reference pictures to be used for decoding a subsequent picture, wherein the maximum number of storable reconstructed pictures is determined as same, 2 times or 4 times of predefined number based on relationship between a shift operation value of the maximum frame size of pictures and the frame size of the input pictures.
