Claims
- 1. A record disc for storing a composite signal that includes segments of video information and corresponding segments of audio information related to the video information, comprising:
- a plurality of circular video information-containing tracks having a video information segment stored therein in real-time, each said video information segment containing a single video frame in conventional video format including a conventional type of video synchronizing signal; and
- a plurality of circular audio information-containing tracks, each said audio information-containing track corresponding with one of said video information containing tracks and having at least a portion of an audio information segment which has a prescribed real-time length related to said single video frame in said corresponding video information containing track, said audio information segment stored therein in time-compressed digital data format, each of said audio information segments including packets of digital data interleaved with said conventional type of video synchronizing signals, adjacent ones of said audio information packets on said disc representing a continuous portion of the stored audio information segment; and
- wherein each pair of audio information-containing track and corresponding video information-containing track includes a coded signal, included in said conventional video synchronizing signals in one of said audio information-containing tracks or said video information-containing tracks, which is indicative of an equivalent real-time length of the respective time-compressed audio information segment, to indicate how long said video signal should be displayed.
- 2. A disc as in claim 1, wherein said circular tracks are concentric tracks.
