Abstract
A transmitter transmits data via a broadcasting link consisting of a satellite link. Receivers receive the data, and verify whether they have successfully received the data. Only when having failed to successfully receive the data, some of the receivers, which can transmit information to the transmitter, transmit retransmission requests for requesting the retransmission of the data via a communication link consisting of the Internet. When retransmission requests are transmitted, the transmitter receives only the retransmission requests and totals them. In addition, the transmitter transmits the data requested to be retransmitted, based on the total via the broadcasting link. The receivers receive the retransmitted data.
