Abstract A record disc for storing a composite signal that includes segments of audio information and corresponding segments of video information. The disc contains a succession of consecutively arranged substantially circular and concentrical information tracks including audio information-containing tracks and separate video information-containing tracks. Each of the audio information-containing tracks has at least a portion of an audio information segment stored therein in time-compressed digital data format, and each of the audio information segments includes packets of digital data interleaved with conventional video synchronizing signals, with adjacent audio information packets representing a continuous portion of the stored audio information segment. Each of the video information-containing tracks has a video information segment stored therein in real time, and each video information segment contains a single video frame in conventional video format including conventional video synchonizing signals.
A record disc for storing a composite signal that includes segments of audio information and corresponding segments of video information, comprising: a succession of consecutively arranged substantially circular and concentrical information tracks including audio information-containing tracks and separate video information-containing tracks; each of said audio information-containing tracks having at least a portion of an audio information segment stored therein in time-compressed digital data format, each of said audio information segments includes packets of digital data interleaved with conventional video synchronizing signals, adjacent audio information packets representing a continuous portion of the stored audio information segment; each of said 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 conventional video synchronizing signals; and wherein: the composite signals stored in said disc includes a coded signals, 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 the equivalent real-time length of the respective time-compressed audio information segment.
