Abstract
A method for modulating a video signal. Frames of a plurality of frames are selected for modulation. A first magnitude alternation pattern is designated for each of a first area of a field of the selected frames. A second magnitude alternation pattern is designated for each of a second area of the field of the selected frames. The intensity of a plurality of pixels of a plurality of scan lines of the field of the selected frames is altered as designated by either the first magnitude alternation pattern or the second magnitude alternation pattern.
