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.

Method and system for enhanced modulation of video signals

A method, apparatus and system for signal modulation. A plurality of pixels are selected in a pattern such that a first pixel group of the plurality of pixels is unpaired with a second pixel group of the plurality of pixels throughout the pattern in a portion of a video signal. The intensity of the plurality of the pixels is altered at a constant magnitude in the portion of the video signal pursuant to the pattern in a substantially invisible way.

Methods and systems for encoding and decoding audio signals are described. In one embodiment, a first DTMF tone in an audio signal may be identified and decoded. A second DTMF tone in the audio signal may be identified and decoded at a time delay from the first DTMF tone. A requested action is determined for an electronic figurine associated with the first DTMF tone and the second DTMF tone. The second DTMF tone is different than the first DTMF tone. Additional methods and systems are disclosed.

Methods and systems for encoding and decoding audio signals

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.

Methods and systems for improved modulation of video signals

A system for transmitting a modulated video signal to be presented on a digital display device, the video signal having a first frame and a second frame, the first frame and the second frame each comprised of a plurality of pixels, the system comprising a signal source for generating a video signal, an encoder, the encoder comprising a means for receiving the video signal from the signal source, a means for selectively altering luminance of the pixels of the first frame and the second frame of the video signal to represent a signal presence or signal absence and thereby creating a modulated video signal, and a means for providing the modulated video signal to a broadcast source, and the broadcast source for providing the modulated video signal from the encoder to a digital display device.

Method and system of detecting signal presence from a video signal presented on a digital display device

A method and system for encoding a content signal having one or more content segments. The one or more content segments of the content signal are identifying or obtained. One or more encoded patterns are superimposed or inserted in a segment portion of at least one of the one or more content segments by use of an insertion method that renders the one or more encoded patterns substantially invisible within the content signal. A method for detecting an encoded message within an encoded content signal. A pattern format is identified in at least one of the content segments. One or more encoded patterns are extracted from the one or more pattern formatted identified content segments. The one or more encoded patterns are decoded. The encoded message decoded from the encoded content signal is utilized.

Pattern-based encoding and detection

A system for transmitting auxiliary data within a modulated video signal from a broadcast source to a hand-held device with a slot, the system comprising the broadcast source comprises means for transmitting auxiliary data to the slotted hand-held device via the modulated video signal; an interface device electronically coupled to the hand-held device via the slot and comprises a card microcontroller, a receiver electronically coupled to the card microcontroller for receiving the modulated video signal from the broadcast source, and circuitry electronically coupled to the card microcontroller and the receiver for demodulating the modulated video signal and reproducing the auxiliary data, and transferring the auxiliary data to the hand-held device via an interface protocol, and the hand-held device with the slot comprises a microcontroller for processing the signal auxiliary data received via the interface protocol from the interface device.

Method and apparatus for modulating a video signal with data

A system for selectively increasing and decreasing the intensity of scan lines in a plurality of fields of a video signal over a time interval and not increasing or decreasing the intensity of the video scan lines in the remaining plurality of frames, thereby enabling a decoder to use an average intensity value comparison or to accumulate the differences in signal strength when fields are changing state from encoded to unencoded or encoded to unencoded to determine whether an auxiliary signal is present during the time interval.
