Method and system for enhanced modulation of video signals

A method for modulating a video signal with a carrier signal, the video signal having one or more frames, each frame having a plurality of scan lines, each having a plurality of pixels, the method comprising:

• selectively designating in an irregular configuration the plurality of scan lines of at least one field of the frames as up lines or down lines;
• and
• selectively increasing the intensity of pixels of the up lines and decreasing the intensity of pixels of the down lines thereby creating a carrier signal within the video signal.

A method for modulating one or more frames of a video signal, each of the one or more frames having a plurality of scan lines, each of the plurality of scan lines having a plurality of pixels, each pixel having an intensity, the method comprising:

• designating the plurality of scan lines in a field of the one or more frames in a pattern such that the plurality of scan lines are not paired throughout the field;
• and
• altering the intensity of the plurality of the pixels of the plurality of scan lines at a constant magnitude pursuant to the pattern in a substantially invisible way thereby creating a modulated video signal.
