General color-receiver design considerations
Transactions of the IRE Professional Group on Broadcast and Television Receivers · 1953
Acquaintance with the complete color television signal is necessary before it is possible to discuss color receivers. This signal consists of the normal monochrome television signal (i.e. luminance, deflection sync, and sound 8ignals) to which the coloring information has been added This added information consists of a modulated color subcarrier, called the chrominance signal, and a color synchronizing signal which supplies a phase reference for the chrominance signal. Black-and-white receivers reproduce only the luminance and sound. Color television receivers must, in addition, insert the coloring information present in the chrominance subcarrier into the black-and-white picture. The author then describes color receiver systems and their circuitry.
