Method, system, and apparatus for communication by means of transmitted signals over visual media
Abstract:
A communication method, system, and apparatus are provided that transmits supplementary communications combined with standard television or other visual media (e.g., cable, satellite, video, pre-recorded video, IPTV, Internet, print media) to a viewer/reader. The invention permits a standard television system or other visual media system to transmit supplementary digital data to the viewers along with the normal visual image to provide interactivity. The invention includes an electronic device that optically receives the transmitted supplementary digital data sent along with the visual image. Using the method described, a transmitting facility is able to transmit supplementary data to the device without interfering with its regular programming. The supplementary data can provide a means for added interactivity (e.g., by providing supplemental data for marketing, promotions games, entertainment, education, coupons, and the like).
