Abstract

PURPOSE: To keep the information transmission quality high while reducing the cost of equipment by using a switched line or the like as the transmission line of an information request signal of less data and using a communication satellite for an information signal of much data.
CONSTITUTION: A terminal machine 2 is installed in each user which closes a contract to request information. When the user inputs request information with keys, the information request signal is outputted to a central information controller 1 from the terminal machine 2 through a wire network 3. The central information controller 1 retrieves information corresponding to the inputted information request signal and converts retrieved information and a control signal to a radio signal and outputs this signal to a communication satellite 4. When the communication satellite 4 transmits the radio signal to terminal machines 2 in a service area after repeating it, terminal machines 2 receive the radio signal from the communication satellite 4 with a designated reception frequency band and transmit request information.
