The invention is an add-on device which allows programming of an existing VCR (video cassette recorder) via standard phone lines. With it attached to a VCR, the user is able to call home and advance program the invention to turn on the VCR at a certain time, change to a desired channel, and start and stop recording at a certain time. These commands would be transferred and entered through the use of standard telephone "Touch Tone" signals. A voice-synthesized response from the invention would return through the phone lines to verify correct instructions. No electrical connection is made directly to the VCR. In addition, no permanent physical or visual alterations of the VCR are made. Thus, the invention is designed to remain mounted to the rear of the VCR indefinitely, since it will not hinder the normal functioning of the VCR, nor its remote control. It also may be removed without damage and installed on another VCR, if desired.
