PROBLEM TO BE SOLVED: To prevent the redundancy of an FEC (forward error correction) from being excessively increased by discriminating the properties of an error. SOLUTION: A data receiver 12 decides a burst error based on the error generation circumstances of data received from a data transmitter 11, and transmits the property-based error information to the data transmitter 11. The data transmitter 11 sets the redundancy of an FEC processing part 1104 based on the error ratio of an error excluding any burst error based on the received property-based error information.
