The MPEG2 standard is expected to be the most promising method for encoding/coding motion pictures of the next-generation digital video discs (DVD). Recently we have developed a variable frame rate method for the DVD systems. In this method the compression efficiency of the information recorded into the discs is extremely improved by not only changing the encoding rate but also the frame rate at the same time. The scheme for realizing variable frame rate is that, when recorded, the data corresponding to appropriate flames of the moving pictures are deleted and, when reconstructed, the frames before the deleted frames are repeatedly read out.
