Abstract
PURPOSE:To supply a composite video signal with high quality by outputting R, G and B color data converted by a color pallet as R, G, and B video signals, and outputting a luminance signal, two color difference signals, a color burst signal, and a composite synchronizing signal as the composite video signal by synthesizing them. CONSTITUTION:The color pallet 3 converts a color code supplied from a display control device to the R, G, and B color data, and inputs them to a D/A converter 7 and a matrix conversion circuit 9. The R, G, and B color data inputted to the matrix conversion circuit 9 are converted to the luminance signal(Y signal), a red color difference signal(R-Y signal), and a blue color difference signal(B-Y signal) expressed in digital values. A balanced modulation circuit 10 performs the balanced modulation of chrominance subcarriers with different phase angles by the (R-Y) signal and the (B-Y) signal. A color burst signal generation circuit 14 generates a digital color burst signal. And the Y signal including a synchronizing signal and the above stated four signals converted to analog values are synthesized by a synthesis circuit 19, then, it goes to the composite video signal.
