Abstract: A screen time control device includes a source interface for receiving a video signal, a processor connected to the video source interface for overlaying the video signal with a translucent signal to produce an overlaid video signal, and a device interface connected to the processor for receiving the overlaid video signal and providing the overlaid video signal to the display device. The processor substitutes the translucent signal in the overlaid video signal with a parental signal, where the parental signal can be a substantially opaque overlay signal that masks an image on the screen of the display device to prohibit viewing of the screen, a textual message, or a combination of both.
