PROBLEM TO BE SOLVED: To improve reliability of communication in a data transmission/ reception system. SOLUTION: When sequentially transmitting data from a data transmitter 2 to a data receiver 3 in each unit data, the same data as the unit data are preliminarily sequentially transmitted in each unit data as error recovery data when the error occurs in the unit data, so that even when the error occurs in the unit data constituting data to be transmitted, error recover processing can be easily carried out. Consequently, the reliability of communication is improved.
