How to read in the RGB value of a certain pixel on the screen which is broadcasted?

Hi, I'd like to make a C++ program that can read the RGB value of the certain pixels of every frame on TV screen which is broadcasted, and save it simultaneously with the broadcasting.
If so, what is the best way of doing it and the hardware requirement?
And if it is possible can it work at a scanning-line?
And would you give me some tip for my program?
