Vorrichtung zur Steuerung einer Farbvideowiedergabe

A device for controlling a color video display which includes ladder resistor units (41, 51) having a plurality of taps; a clock signal generating unit (11) for generating four-phase clock signals ( phi 1 - phi 4) having the same frequency as the frequency (fs) of a sub-carrier from a clock signal having a frequency which is four times the frequency of the sub-carrier, and a color signal generating unit (13-22) for receiving data corresponding to colors to be displayed and generating color signals by successively selecting taps of the ladder resistor units corresponding to the colors to be displayed, in synchronization with the four-phase clock signals. The generation of color signals having a precise phase angle relationships are ensured by this device.
