ABSTRACT:
A method and apparatus for carrying digital information in video signals onto the recording format of audio compact disc (CD) systems. Input signals are divided into 8-bit samples and groups of thirty-three samples are treated as a frame. Upon encoding in accordance with the CD format, the frame is made to contain 576 bits which are converted to one hundred ninety-two 3-bit samples. The 3-bit samples are converted to analog levels and those analog levels comprise the video signals. Such a video signal can advantageously be stored in a video disc with exactly one frame of digital data being contained in the video line and stored in one track of the disc. In retrieving the information, the CD format sync code is detected and augmented, and the video line is fed to circuitry that decodes signals having the standard CD format.
