US Patent 8150990 Enhanced advertising using dual streaming video

A communications system particularly suited for a distributed network of computers such as the World Wide Web or the Internet. Connected to the distributed network is a broadcast computer which simultaneously communicates two streams of video. The first stream of video contains entertainment; the second stream of video contains commercial content. The receiver of the two streams has both streams displayed simultaneously and is able to select which stream's audio component is communicated to the user's computer's loudspeakers. In one embodiment of the invention, the user is also able to replace the commercial channel with another commercial channel.
