As shown in FIG. 2, the first input buffer 120 of the first format converter 100 receives and temporarily stores a predetermined color signal and a luminance signal through the first input port 110.

Subsequently, the first control unit 130 reads the color signal and the luminance signal stored in the first input buffer 120 and stores the color signal in the first memory 140 as a predetermined signal so that the color signal can be displayed on the flat panel device 400. The conversion is transmitted to the first output buffer 150.

Here, the first output buffer 150 temporarily stores the converted color signal transmitted from the first controller 130 and outputs the corresponding signal to the first output port 160.

Subsequently, the first output port 160 receives the color signal converted through the first output buffer 150 and transmits the color signal to the MUX 300, and a main screen on which the corresponding color signal is displayed is implemented on the flat panel device 400. The horizontal / vertical synchronization signal, the data enable signal, and the clock signal are output to the flat panel device 400 as much as possible.

In addition, a double window may be implemented by adjusting the size of the data enable signal output from the second output port 260.

As a result, the main screen size of the flat panel device 400 is determined by a horizontal / vertical synchronization signal, a data enable signal, and a clock signal transmitted from the first output port 160 of the first format converter 100. The sub picture size is determined according to the size of the data enable signal transmitted from the second output port 260.
