DATA RECEIVING TERMINAL, DATA DISTRIBUTION SERVER, DATA DISTRIBUTION SYSTEM, AND DATA DISTRIBUTION METHOD

摘要

A data receiving terminal (20) has a broadcast wave receiving function and a communication wave sending/receiving function. A communication control unit (210) receives data from a data distribution server (10) by using the broadcast wave receiving function. When having determined that there is a defect portion, a determination unit (220) determines whether or not to repair the defect portion according to at least one of a communication status between the data receiving terminal (20) and the data distribution server (10) and a data relevant status related to the data. When the determination unit (220) determines that the defect portion should be repaired, the communication control unit (210) requests the data distribution server (10) to resend the defect portion by using the communication wave sending/receiving function and receives the defect portion sent from the data distribution server (10) according to the request for resending by using the communication wave sending/receiving function.
