Abstract
A device that controls background music interspersed with commercial messages by using an unmodified Compact Disc (CD) player loaded with custom discs. The custom discs provide the music and commercial content, and inform the device of the rate at which the commercial messages should interrupt the music. Dual Tone Multi Frequency (DTMF) signals are employed to provide control signals to the device to inform it of the disc type, track end, and rate of interspersion of commercial messages. The CD player is controlled by either a wired or wireless remote.
