A technique is described whereby time-frame sequencing is used in color video graphic display so as to improve the resolution and eliminate movement problems during color video transmission. The concept increases from sequencing by as much as sixty times per second instead of the normal twenty times per second. Normal color television (NSTC Standard) composite video transmits the synchronization, intensity and color information as one signal. The synchronization information is time multiplexed with the intensity and color information (picture) and the picture information is frequency multiplexed. The intensity information is restricted to a bandwidth of 3 megahertz and the color information is phase (hue) and amplitude (saturation) modulated on a subcarrier at 3.58 MHz.
