发明名称 BROADCAST SYSTEMS WITH WIRELESS REQUEST CHANNEL
摘要 An information broadband broadcast system selected from cable and satellite for broadcasting requested information from a selected information source, including the Internet (17), to one or more selected subscriber stations (10) includes an independent backhaul channel for communicating information request signals from a subscriber station to one or more central processing stations. The system includes a data broadcast station for transmitting requested data from the selected data source and central station via the data broadcast station to the one or more selected subscriber stations. The high-data rate broadcast station forwards requested data from a data source to the data broadcast station. A backhaul satellite (14) communication system, independent of the broadband broadcast system, has a backhaul satellite ground terminal (16) for coupling information request signals from backhaul satellite communication system to high data broadcast station terminal (19). Each subscriber station has a broadband broadcast receiver (21).
