PROBLEM TO BE SOLVED: To provide a data transmission system capable of reducing a circuit scale for correcting errors information, when transmitting a packet using an operation system and a standby system, and a data transmission method. SOLUTION: Transmission data 108 transmitted from a transmission data buffer 106 of an information processing part 105 is input into a transmission packet generation part 109, and is here divided into a packet unit, and error correction code for each of 3 packets is calculated. The calculation result is assembled as an error information correction packet 113 and is transmitted, from a standby system data transceiving part 102 to a standby system transmission line 104. A packet divided in the transmission packet generation part 109 is transmitted as a transmission packet 111, from an operation system data transceiving part 101 to an operation system transmission line 103.
