Abstract
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.
