Abstract
A method and apparatus for simulating movement within a multi-dimensional space by selecting and reproducing a particular one of a plurality of selectable sequences of video images subsequent to a given sequence of video images. The apparatus comprises an interactive random access video disc system for storing the sequences of video images. Video image windowing means provides as a video output only a predetermined 'window' portion of each retrieved video image. The window portion of an ending image of a given retrieved sequence substantially duplicates the window portion of a starting image of a retrieved sequence reproduced immediately subsequent to the given sequence, thereby providing a relatively imperceptible transition between sequences. A method for numbering frames on the video disc ensures that a jump between images in any sequence or to an image in a subsequent sequence can be accomplished within a predetermined number of tracks and within a predetermined time, in order to prevent pauses or blankings of the output video images.
