ABSTRACT:
An apparatus and method for converting a video signal output from a composite video instrument, by which the operating state of a system or the manufacturing state of a system board can be easily recognized, is disclosed. When a normal video signal is not input, a monochrome/color signal component is output to be displayed on a screen. The monochrome/color signal component has either a value internally set by a system, or a value set in accordance with externally supplied data to then be displayed on a screen. The apparatus includes a monochrome/color signal separator for receiving a quantized composite video signal and separating a monochrome signal component and a color signal component, a color signal demodulator for separating a color component from the color signal component output from the monochrome/color signal separator, a lock detector for detecting whether a signal input to the color signal demodulator or a signal output therefrom is normal, a color signal controller for multiplexing the color signal component output from the color signal demodulator and the variably set color signal component, and a monochrome signal controller for multiplexing the monochrome signal component output from the monochrome/color signal separator and the variably set monochrome signal component.
