Abstract
An on-screen display/video signal processor is disclosed which prevents the output of video signals while generating a fast blanking signal when on-screen display mode selection key is selected by a user. The on-screen display/video signal processor has a video signal muter for removing video signals with an input of the fast blanking signal. The quality of an on-screen display can be increased with a generation of the fast blanking signal and a rapid removal of video signals.
Claims18
In an on-screen display/video signal processor having means for generating on-screen display signals and a fast blanking signal according to an on-screen display mode selection signal generated by an on-screen display mode selection key, means for amplifying video signals, means for converting the amplified video signals to signals of video signal levels and means for amplifying the signals of video signal levels to be supplied to a cathode-ray tube, the on-screen display/video signal processor comprising:
- means for muting the video signals with an input of the fast blanking signal in order to remove the video signals rapidly according to a selection of the on-screen display mode selection key.
An on-screen display/video signal processor comprising:
- means for generating an on-screen display mode selection signal;
