ABSTRACT:
A method and device for displaying a back-screen in a video signal processing system does not require a separate back-screen generating circuit in order to display the back-screen. Instead, an on-screen signal for indicating characters is used to display the back-screen. A determination signal is detected to determine whether a video signal input is received, and if the input video signal is not received, a microcomputer generates an extended on-screen signal to display the back-screen. If the video signal input is detected during display of the back-screen, the extended on-screen signal is blocked, stopping display of the back-screen.
