Abstract
A method of communicating a video image via an audio communication signal includes the steps of identifying, for a given pixel location of the video image, a set of samples within a stored audio signal having a corresponding bit pattern, generating a marker identifying the location of the given pixel in the video image, and multiplexing the stored audio signal and the marker such that the marker appears within the stored audio signal proximate to the set of samples having the corresponding bit pattern. This method can also include the steps of transmitting the multiplexed signal to a destination device, demultiplexing, at the destination device, to recover the marker and the corresponding bit pattern, illuminating a display at the given pixel location according to the corresponding bit pattern, and converting the corresponding bit pattern into an analog audio signal.
