ABSTRACT:
A method for modulating one or more fields of video signal (18) with auxiliary signal (20) by use of an encoding improvement, the one or more fields having one or more sub-fields, the one or more sub-fields having a plurality of odd and even scan lines, the plurality of odd and even scan lines having a plurality of pixels, the plurality of pixels each having an intensity comprising obtaining on encoder (12) the video signal from signal source (10), selectively designating on encoder the plurality of odd and even scan lines as up lines or down lines for at least one of the one or more sub-fields for at least one of the one or more fields, calculating an amount of intensity adjustment for the pixels of the plurality of odd and even scan lines on encoder, and adding intensity to the up lines and subtracting intensity from the down lines according to the amount of intensity adjustment for the pixels of the scan lines of video signal on encoder.
