Apparatus in accordance with the subject invention controls a cable box (i.e., the source of its own video input signals), and monitors the television signals received from the cable box, in a 'closed loop' manner. By monitoring an appropriate signal the controller of the VCR can detect perturbations of signal level which indicate that the cable box has changed channels.
