Abstract
A color reference signal is inserted during the vertical blanking interval of a transmitted television waveform, for utilization by the described apparatus in automatically setting the hue and saturation of the display of an NTSC or a PAL receiver. The apparatus responds to the transmitted burst signal to set the frequency and phase of the sub-carrier oscillator of the receiver and, further, to the transmitted reference signal to correct any such inaccurate setting of phase as is caused by adverse conditions of networking and transmission from the studio to the receiver.
