Abstract
An information delivery system includes terminals receiving data via a satellite-communication system, and a user center having a destination-conversion table which lists a satellite-system receiver ID with respect to each ground-network address of the terminals, and, upon receiving a request for data delivery via an intra-network, obtaining satellite-system receiver IDs from ground-network addresses indicated as destinations of the data delivery by referring to the destination-conversion table so as to deliver requested data and a reception-control program to the destinations via the satellite-communication system. The terminals use the reception-control program to check the data-reception conditions when receiving the requested data and the reception-control program, and send a request for a repeat of the data delivery to the user center via the intra-network if the data-reception conditions are not satisfactory.
