| 20080198923 | CONTENT SIGNAL MODULATION AND DECODING - Methods and systems for content signal encoding and decoding are described. A message to be encoded into a content signal may be accessed. The content signal may include a plurality of frames. One or more symbols to be encoded for the message may be derived in accordance with a message translator. A particular symbol of the one or more symbols may be embedded into at least one frame of the plurality of frames by altering a total pixel variable value of the at least one frame. | 08-21-2008 |
| 20090141793 | DUAL CHANNEL ENCODING AND DETECTION - Methods and systems for dual channel encoding and detection are described. In one embodiment, Auxiliary data may be encoded in an audio portion of one or more frames of a content signal based on an audio encoding technique. The auxiliary data may be encoded in a video portion of the one or more frames based on a video encoding technique. The encoding of the auxiliary data in the audio portion and the video portion may produce a modulated content signal. The modulated content signal may include one or more dual encoded frames. The dual encoded frames may include the auxiliary data encoded within the audio portion and the video portion of the one or more frames. Additional methods and systems are disclosed. | 06-04-2009 |
| 20100248687 | METHODS AND SYSTEMS FOR ENCODING AND DECODING AUDIO SIGNALS - 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. | 09-30-2010 |
| 20100261514 | HAND-MANIPULABLE INTERFACE METHODS AND SYSTEMS - Methods and systems for a hand-manipulable interface are described. In one embodiment, a manipulable interface device may have a movable portion and a non-moveable base portion. A position sensing subsystem may be deployed in the manipulable interface device to detect a user interaction based on movement of the movable portion relative to the non-movable portion. A control unit may be coupled to the positioning sensing subsystem to translate the user interaction into an instruction on the manipulable interface device and generate a visual display on the manipulable interface device based on the instruction. Additional methods and systems are disclosed. | 10-14-2010 |
