摘要

A predictive video coding device, comprising: input means (101) that introduce a plurality of images that constitute a video sequence; encoding means (105, 106, 107) that carry out a predictive coding of the images and generate compressed image data, the predictive coding of a current image being carried out using a plurality of reference images that have been encoded and subsequently previously decoded and reproduced; reconstruction means (108, 109, 110) that decode compressed image data to reconstruct a reproduced image; means (104) for storing images that store at least said reproduced image as a reference image that will be used to encode a subsequent image; and intermediate memory management means (114) that control the image storage means (104), where, before the current image processing, the intermediate memory management means (114) control the storage means (104) of images based on BD memory description information [k], the BD memory description information [k] being relative to a plurality of reference images that are used in the predictive coding of the current image, and, at at the same time, they encode the BD buffer description information [k] using prediction with reference to a BD buffer description information [m] with m k, relative to a different image of the current image, and, a Next, the encoded data thereof is added to the compressed image data, the buffer description information describing a number of reference images to storage ar in the buffer and information to identify which reference image is to be stored.
