    • PROBLEM TO BE SOLVED: To provide an economical and interactive information distribution system for providing a real-time mutual relation between a subscriber and a service provider (in a relatively short waiting time) anytime while an information request is indicated. SOLUTION: An interactive information distribution system includes service provider equipment for generating an information stream that is coupled to an information channel and transmitted to subscriber equipment. The service provider also generates a command signal that is coupled to a command channel and transmitted to the subscriber equipment. The service provider also receives information manipulation requests from the subscriber via a back channel. A communication network supporting the information channel, command channel and back channel is coupled between the service provider equipment and the subscriber equipment.
