A system and method for interactive broadcast of Internet web pages, or the like, on dedicated downstream channels (16) in a cable television system (10) or the like facilitates hyperlinking by a user from a broadcast television program to a web page, or between web pages, for example. In one embodiment, each user's set top (14) is programmed with channel mapping information that maps each hyperlink request to a particular channel and time where the requested information is being broadcast in a multiplexed information stream. In one embodiment to facilitate picture-in-picture capability using a single tuner, the tuner (40) in the set top (14) briefly tunes away from the video program to the appropriate data channel for receiving the hyperlink information. |
