摘要

PROBLEM TO BE SOLVED: To continue a high-speed data delivery without a pause even in the interruption of the communication with some delivery servers by failure during data split delivery in split delivery of data. SOLUTION: A plurality of delivery servers split-delivers data to be delivered to a client 1 according to a delivery request from the client 1, and another delivery server simultaneously delivers error correction information to the split-delivered data. The client 1 generally combines the delivered data without using the error correction information to restore the data to be delivered. When the data from some delivery servers cannot be received by failure, or the transfer speed is a prescribed speed or less, the client 1 restores the data to be delivered by use of the error correction information.
