Abstract
A video disc recording and reproducing system in which a program is stored on a video disc to eliminate the need for the user to manually input a control program. A program and control signal is recorded in place of at least a portion of one of two audio tracks on a video disc along with video signals. The video disc player of the system includes modulator circuits which demodulate the video and audio signals from the disc, a central processing unit connected to the output of the demodulator circuit for demodulating the audio signal for detecting the control signal and program recorded on the video disc, and a memory for storing the control signal and program. The central processing unit controls the memory for storing the program and control signal at predetermined locations corresponding to the state of the control signal.
