An optical disk system is presented which stores index information allowing playback of selected portions of a presentation recorded upon an optical disk, along with an associated method. The index information includes navigation data indicating the physical location of a beginning of a selected portion of a presentation stored upon the optical disk. One embodiment of the optical disk system includes a memory unit operably coupled to a disk drive unit and an input device. The disk drive unit retrieves identification data, encoded video data, and navigation data stored upon an optical disk (e.g., a DVD). The encoded video data may be, for example, a recorded presentation such as a movie. The input device produces an output signal in response to user input, wherein the output signal indicates a beginning of a selected portion of the encoded video data. The memory unit includes a non-volatile portion for storing the identification data and the index information. The index information may be retrieved from the memory unit at a later time. The optical disk system also automatically accesses the selected portion of the encoded video data indicated by the retrieved index information, eliminating the need for manual access by the user. The optical disk system thus allows the user to experience previously selected portions of a presentation (e.g., favorite movie scenes) with minimum effort and without having to view the entire presentation from beginning to end.
