Abstract
In the present invention, reconstructed images for prediction are stored in uncompressed reference picture memory and compressed reference picture memory. A video decoder stores in uncompressed reference picture memory a reconstructed image of a frame to be decoded which has been generated on the basis of a prediction, and among reconstructed images which have been stored in the uncompressed reference picture memory, compresses a reconstructed image that will not be used for prediction of the frame to be decoded and stores the image in the compressed reference picture memory. Using the reconstructed images which are stored in the uncompressed reference picture memory and the compressed reference picture memory, the video bitstream is decoded into a video.
