A method and system are provided for controlling tint of component video signals.
The system includes a first input for receiving a first component video signal;
a second input for receiving a second component video signal; circuitry including
a first differential amplifier and a second differential amplifier for receiving
the first and second component video signals from the first and second inputs,
respectively; a first output connected to the circuitry for outputting a first
tint control adjustment signal for the first component video signal; and a second
output connected to the circuitry for outputting a second tint control adjustment
signal for the second component video signal. The first outputted signal is represented
as V+kU-2ckU and the second outputted signal is represented as U-kV+2ckV, where
V represents the first component video signal, U represents the second component
video signal, k is a constant, and c is a value greater than or equal to zero and
less than or equal to one.
