To produce a simultaneous television image in color, three communication channels must be available. The first of these may be used to transmit the scene brightness, the second the degree of color saturation, and the third the hue or color. For compatibility the brightness is transmitted as amplitude modulation in the usual way. A subcarrier is introduced to carry the other two pieces of information as amplitude and phase modulations. The optimum loading of these two auxiliary communication channels is the major consideration of this paper.
