Abstract
A system and method for providing an interactive, visual complement to one or more audio programs. In one aspect, the system comprises an audio subsystem for generating an audio signal corresponding to a sound recording. The system also comprises a video subsystem for generating a video image specification based, at least in part, on the sound recording. In one aspect, the audio signal and video image specification are transmitted to an audio/video signal transmission system. The transmission system receives the video image specification and generates a video signal that conforms to the video image specification. The video signal and the audio signal are transmitted to at least one consumer receiver. In this way, the system provides a visual complement to an audio program.
