摘要

A motion video predict coding device comprises: an input means for receiving an input of a plurality of images which configure a motion video; a coding means for predict coding a subject image with an image which is restored after having been coded in the past as a reference image and generating compressed image data; a restoring means for decoding the compressed image data and restoring the image data to a playable image; an image storage means for storing the playable image as a reference image for contiguous image coding; and a buffer administration means for controlling the image storage means. The buffer administration means controls the image storage means based on buffer description information BD[k] which relates to the reference image for coding (prior to predict coding the subject image), refers to buffer description information BD[m] of an image which differs from the subject image and codes the buffer description information BD[k], and adds the coded data to the compressed image data.
