Abstract
A system that incorporates teachings of the present disclosure may include, for example, a controller configured to obtain information associated with media content, to generate a first group of tones representative of the information associated with the media content, and to generate a media stream comprising the media content and the first group of tones; and a communication interface configured to transmit the media stream to a media device whereby the media device presents the media content and a sequence of tones, where the sequence of tones is generated based at least in part on the first group of tones, where the first group of tones comprises high frequency tones and low frequency tones, and where one of the high and low frequency tones represents a binary one and the other of the high and low frequency tones represents a binary zero. Other embodiments are disclosed.
