Abstract:

This invention relates to a method and apparatus for preventing the fast-forwarding of a video tape cassette through a commercial advertisement recorded at the beginning of the tape. The methods disclosed make use of the standard photoelectric circuitry normally built into a video cassette recorder for sensing the transparent ends of a tape and stopping the recorder. Actuation of the standard stop circuitry may be accomplished by adding an auxiliary light source and associated operating circuitry to illuminate the photocell thereof.
