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

摘要

FIELD: radio engineering, communication.SUBSTANCE: disclosed data receiving terminal (20) has a broadcast signal receiving function and a communication signal sending/receiving function. A communication control unit (210) receives data from a data distribution server (10) using the broadcast signal receiving function. When it is determined that there is a defective area, a determination unit (220) determines whether to repair the defective area in accordance with at least one of: a communication status between the data receiving terminal (20) and the data distribution server (10) and the data relevance status associated with the data. When the determination unit (220) determines that the defective area needs repairing, the communication unit (210) requests the data distribution server (10) to resend the defective area using the communication signal sending/receiving function and receives the defective area sent by the data distribution server (10) in accordance with the resend request using the communication signal sending/receiving function.EFFECT: preventing wastage of communication resources when repairing defective areas when broadcasting data.36 cl, 13 dwg
