Abstract
The present invention provides a reception apparatus for receiving data from a transmission apparatus in one direction, and a transmission apparatus for transmitting data with regards to the reception apparatus in one direction. If the reception apparatus detects an error in the received data, the reception apparatus informs the transmission apparatus about the error in the received data by switching over one or more communication lines forming a connection with the transmission apparatus. If the transmission apparatus detects a switchover of the one or more communication lines, the transmission apparatus re-transmits the data in which the error occurred to the reception apparatus. According to the present invention, the occurrence of data errors in one-direction data communication is easily recognized, and the reliability of the one-direction data communication is improved.
