PROBLEM TO BE SOLVED: To improve data transmission efficiency at transmission from a data transmission device to a data reception device than before.SOLUTION: A data transmission device includes: a generator unit which generates, during transmitting a first packet to one of a first communication line and a second communication line and when transmitting a second packet to another, a second field of the second packet to be transmitted to the other, based on a first field of the first packet which is in transmission to the one; and a transmitter unit which transmits the second field, generated by the generator unit, to the other. The data reception device includes a detector unit which detects a predetermined data position in a packet received through the other, based on packet fields respectively received through the first communication line and the second communication line.SELECTED DRAWING: Figure 1 |
