Abstract

PURPOSE: To attain the high using efficiency of such a satellite circuit that is suited to transmission of the large capacity data and not economical with transmission of the small capacity data, by using a satellite circuit for a link having a large quantity of data to be transmitted and a ground circuit for a link having a small quantity of data respectively.
CONSTITUTION: An earth station B contains a receiver 1 for broadcast satellite and a captain converter 2. When an access is given to a captain center 4 of a center station from the station B, a telephone set 3 is connected to a telephone receiver 15 of the center 4 via a ground circuit. When a terminal number is transmitted from the telephone 3, the center 4 delivers the data of a picture data memory 17 to every home via a broadcast satellite 5. In this case, the address data is added to the picture data and the terminal number of the station B is set to an address part. The number of own station is previously supplied to an address memory 11 for a converter 2 of the station B. An address comparison/data selection circuit 10 compares the data of the converter 2 with the received address data. Then the picture data is stored to a picture data memory 12 and displayed to a receiver 8 only when the coincidence is obtained from said comparison.
