a ROM(20) outputting Y, U, V values corresponding to R, G, B values; an adder(27) adding the output(Y) of the ROM(20) and the pedestal level(FL) of composite signals; low pass filters(29,30) filtering the output(U,V) of the ROM(20); a multiplexer(33) outputting the output data of the low pass filters(29,30), a -U converter(31) and a -V converter(32) selectively according to the selection signal(SEL) generated from a UV selector(24); an adder(34) adding the output of the multiplexer(33) and the output data of the adder(27); a burst generator(23) outputting the burst level value in phase with CSYNC; and a D/A converter(35) converting the digital composite signal of a multiplexer(26) into the analog signals.
