ABSTRACT:
A remote control switching circuit is provided for enabling a person watching and listening to television to edit out unwanted portions of a television program. Thus, while watching television, when an unwanted portion appears, the watcher uses a remote control device for actuating switches which provide for replacing the audio of the television set with the audio of an alternate sound source and for simultaneously dimming the picture on the tube of the television set so that it is only faintly discernible. Then, by viewing the picture tube, the watcher can see by observing the faint image on the screen when to use the remote control device to again actuate, i.e., reverse, the switches for returning to the audio of the program of the television set in place of the audio of the alternate source and for simultaneously brightening the picture on the tube for normal viewing.
