Abstract
Multiple signals received through different transmission mediums are synchronized within a set top box (STB) for subsequent mixing and presentation. For example, a video program transmitted via a cable network is synchronized with a secondary audio program, such as a radio program, received via the Internet. In another example, a video program transmitted via a cable network is synchronized with one or more programmed events, such as directives to display text or graphics or animation, play streaming media, direct a browser to a particular web page, and the like.
