PROBLEM TO BE SOLVED: To relay data while maintaining excellent utilization efficiency of a transmission line and satisfying requests for transmission delay and a transmission error rate of each data.SOLUTION: When first reception data is low delay priority data, a data transmitter transmits first reception data to a device on a downstream side without executing error correction processing, and when the first reception data is low error rate priority data, performs the error correction processing and tentatively stores the first reception data after the error correction processing. After completion of the error correction processing of the first reception data, when second reception data from a device on an upstream side is low delay priority data, the data transmitter transmits the second reception data to the device on the downstream side without executing the error correction processing, and when the second reception data is low error rate priority data, transmits the first reception data after the error correction, which is stored in storage means, to the device on the downstream side. |
