DOUBLE SCREEN DISPLAY CIRCUIT

PURPOSE:To unnecessitate the matching adjustment of hues by making signal demodulation common for a master picture and a slave picture. CONSTITUTION:The video signals of the master picture are switched by a signal switching circuit 11 for master picture, and a signal showing the kind of the output is outputted to a switching circuit 21. Then, a signal processing is executed to the slave picture selected by a signal switching circuit 12 for slave picture. A signal conversion circuit 22 is provided to convert a color/luminance separated signal for this slave picture to a composite video signal. Corresponding to the output of a master signal, either of those signals is selected by the switching circuit 21 and synthesized by a master/slave signal synthesizing circuit 23. Then, the synthesized signal is demodulated by a signal demodulation circuit 24.
