Title:
DATA RECEIVING TERMINAL, DATA DISTRIBUTION SERVER, DATA DISTRIBUTION SYSTEM, AND DATA DISTRIBUTION METHOD
Document Type and Number:
WIPO Patent Application WO/2010/035652
Kind Code:
A1
Abstract:
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 a determination unit (220) determines that there is a defect portion, the determination unit (220) determines whether or not the defect portion should be recovered on the basis of at least one of the communication situation between the data receiving terminal (20) and the data distribution server (10) and the data relevant situation which is a situation relevant to data. When the determination unit (220) determines that the defect portion should be recovered, 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.
