ABSTRACT:
In a video disk recording/playback device for converting a digital video signal or the like into high-efficiency coded data and recording the coded data on a video disk, or for restoring high-efficiency coded data recorded on the video disk and reproducing an output image, wherein said digital video signal is composed of a succession of video signals of a plurality of frames and including an I picture encoded within a frame, a P picture interframe coded by forward motion compensation with reference to said I picture and/or another P picture, and a B picture interframe coded by motion compensation in both directions with reference to said I and/or P pictures temporally preceding and succeeding the B picture, there are further provided a means for recording in an image information table set up on said video disk all of the start addresses of coded data representing selected images such as images to be retrieved and the start addresses of data containing information required for reproducing the coded data. With the above configuration, retrieval of all kinds of images of I, P, and B pictures is possible by recording all of the start addresses of coded data representing selected images such as images to be retrieved and the start addresses of data containing information required for reproducing the coded data in the image information table on the video disk.
