A regulator for controlling access to a home video entertainment device includes a signal multiplexer connected to the output of the home video entertainment device. A video signal generated by the regulator may be overlaid with a portion of the video output from the home video entertainment device. If a timer is expired, the regulator video signal is overlaid with all of the video output from the home video entertainment device. If the timer is unexpired, the regulator video signal is overlaid with only a portion of the video output. The duration of the timer can be increased by inserting token into the regulator.
