ABSTRACT:
Connected to a satellite earth station for transmitting a broadcast signal to a communication satellite, a data (distribution) center publishes contents of stored information on a home page (HP) of the Internet to submit retrieval of users. When each user determines date to be gotten by retrieving on HP, the user transmits a request signal to the date center via a ground Internet or the communication satellite. Responsive to the request signal, the date center returns a reservation signal including a group address and a distribution scheduled time instant to a request source via the communication satellite. A user's terminal receives date with the group address at a reserved time instant, deciphers the date using a key given from the date center separately, and stores deciphered date in a memory thereof.
