    摘要: A method and apparatus for generating and editing audio and/or video data using thumbnail representations of the data. Thumbnail representations are generated in accordance with clips randomly recorded on a disc, or other storage medium, and edit points are designated for the clips. When thumbnail representations are displayed, the disc is rotated at constant angular velocity (CAV). Video data of the thumbnail representations are read from the disc. When a desired thumbnail representation is selected and designated, the disc drive system is switched from CAV drive mode to constant linear velocity (CLV) drive mode. Video are reproduced from the position of the selected thumbnail representations. Since the thumbnail representations are read in the CAV drive mode that is suitable for randomly accessing the disc, the thumbnail representations can be displayed at high speed.

    摘要: A data accessing and reproducing apparatus and method that permits a user to selected desired video clips and perform editing on the clips such that the time needed to display a thumbnail representation is minimized. In an edit mode, thumbnail pictures are arranged and displayed in the order of which edit results are reproduced. These thumbnails may be, for example, a lower resolution, proxy representation of the audio or video data. When data of thumbnail pictures are read from a disc, the data are read in the order of which they have been recorded. The order of which thumbnail pictures are displayed on the screen is different from the order of which they are arranged on the screen, and thus, the seek time for the disc becomes the shortest. Thus, the thumbnail pictures can be displayed at high speed.
