ABSTRACT OF THE DISCLOSURE A video recording disc for use with programmable playback apparatus, wherein information recorded on the disc includes a video signal and a digital program instruction sequence for use by the apparatus in sequencing its operating mode in a prescribed fashion. The recorded video signal includes a carrier that is normally modulated by an audio signal, but that, for a limited number of selected tracks on the disc, is modulated by the digital program instruction sequence, whereby the playback apparatus can operate initially to scan the selected tracks, to recover the recorded program instruction sequence after which the operating mode of the apparatus is controllably sequenced in accordance with the recovered instructions.
