Abstract: A video display system having a forward locking infrared sensor which emits a linear video signal together with a digital graphics generator which generates digital video signals in a plurality of colors; together with a signal video amplifier for amplifying both the linear signal and the high data rate digital signal; the video amplifier having a plurality of curent regulators for regulating the current through a particular resistor where the current regulation is a function of the received linear and digital video signals; the video amplifier also having the capability of current regulation through the resistor in response to variations in the voltage source voltage and thereby eliminating the need for an additional power source voltage regulator.
