Abstract

PURPOSE: To simplify the constitution of circuit block and to increase the video quality, by sequentially storing the signal from the primary color demodulation circuit for small screen in line and by display of it into a part of three primary colors for large screen with simultaneous readout, in the double display color receiver.
CONSTITUTION: The signal B for small screen is outputted as the primary color signals of r, g, b with the demodulation and matrix circuit 42. This signal is written in the r.MEMORY of the memory circuit 46 for r1 signal at the first one line 1H and g2 signal at the next one line similarly. The signals r,g,b written in are simultaneously read out at the clock 49 and selected to the signal A for large screen with the selector switch SW3 and replaced at a part of the large screen. Accordingly, since the signals r,g,b are selected by 1H, the video quality of color small screen can be increased.
