    摘要: 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.

    摘要: A method and system for auxiliary data detection. Data is received on a hand-held device from a display of a signal on a monitor. The signal is visually displayed on the monitor at a frequency. A modulated video signal is received on the hand-held device from a display device. The modulated video signal contains auxiliary data modulated within a video signal in a substantially invisible way. The modulated video signal is demodulated to obtain the auxiliary data. At least one of the data or the auxiliary data is processed to identify a promotional opportunity available through the hand-held device. The user of the hand-held device is notified of availability of the promotional opportunity through the hand-held device.

    摘要: 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.
