To provide a rational retransmission system in which, only when a receiving status of a broadcast wave becomes worse, a retransmission signal is received in accordance with channel information, that a user is viewing, and user positional information by connecting to the Internet, and a video image or the like is outputted to a mobile terminal.

A retransmission system 1 includes a mobile terminal 2 and a retransmission server 5, and the mobile terminal 2 includes: a receiving means 20 for receiving a broadcast signal; a storage means; a receiving status confirming means; a first communication means 30 for receiving a retransmission signal; a second communication means 40 for receiving positional information; and an information transmission control means in which, when it is confirmed by the receiving status confirming means that a receiving status becomes worse, the first communication means 30 is caused to transmit viewing target channel information and the positional information to the retransmission server 5. When the retransmission server 5 receives the viewing target channel information and the positional information from the mobile terminal 2, the retransmission server 5 transmits the retransmission signal corresponding to the received information to the mobile terminal 2.
