BROADCASTING COMPLEMENT DATA TRANSMISSION DEVICE AND BROADCASTING COMPLEMENT DATA TRANSMISSION METHOD, AND BROADCASTING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a broadcasting complement data transmission device and a broadcasting complement data transmission method, and a broadcasting system which can minimize traffic of a communication network when complementing deficiency data of broadcast contents data.SOLUTION: When the broadcasting complement data transmission device receives time information which is a retransmission request of deficiency data including time information from a receiving device 200, based on the time information included in the retransmission request, an HTTP response unit 104 determines whether or not to rebroadcast the contents including the deficiency data. And if the HTTP response unit 104 determines to rebroadcast, the broadcasting complement data transmission device transmits the determination as a response to the error notification receiving device 200, and does not perform transmission of contents via the communication network.
