Abstract
It is desirable that a television receiver provide a prominent visual indication that it is about to automatically turn off. On-screen display (OSD) circuitry automatically reduces the viewable picture area to a small area before turning off the receiver. Reduction of the viewable area may be performed by displaying and gradually enlarging at least one graphically-generated margin of the OSD display.
