Abstract
A system and method for data transmission over an audio jack are disclosed. A particular embodiment includes: an audio interface including an audio jack, the audio interface including a right audio signal interface and a left audio signal interface; a data extractor coupled to the audio interface, the data extractor being configured to receive an audio stream via the audio interface and to isolate data encoded into the audio stream as out-of-phase data tones; and a microcontroller coupled to the data extractor to receive and process the data isolated by the data extractor.
