Abstract
A method for encoding a carrier signal in a video signal, the video signal having one or more frames, the frames each having a first field and a second field, the first field and the second field of each frame having a plurality of scan lines, each having a plurality of pixels with an intensity value indicating brightness, the method comprising selectively designating the plurality of scan lines of the first field of the one or more frames as up lines or down lines, calculating an optimum amount of adjustment to the pixels of the up lines and the down lines, and selectively increasing the intensity value of pixels of the up lines and decreasing the intensity value of pixels of the down lines by the optimum amount of adjustment thereby modulating the video signal with a carrier signal and creating a modulated video signal.
