Hi all,


Is there any method to auto detect the color space of the CP input?  Particularly when the CP is connected by 3-wires (composite sync)


In other words, we have two inputs types arrive at the same pins on the chip, suc as AIN3, AIN2, AIN1


Case 1:   Pr, Y , Pb   (sync on Y) 

Case 2:   R, G , B  (sync on G)


Setting the device to do sampling correctly is no problem, but I have to guess for its color space...obviously it's not always correct
