Patent ID: 8689091

Claim:
A data receiving device for receiving divided transmission data transmitted from a data transmitting device through a plurality of transmission paths, the divided transmission data including the divided data that is transmission target data divided for each transmission path used for data transmission from among the plurality of transmission paths and error detection information generated from the divided data to detect an error, the data receiving device comprising: a timing signal generation unit that generates a timing signal used for receiving the divided transmission data in each of the transmission paths; a data receiving unit that receives the divided transmission data transmitted by the data transmitting device for each of the transmission paths by using the timing signal generated by the timing signal generation unit; and an error detection unit that extracts the error detection information from the divided transmission data received for each of the transmission paths by the data receiving unit, detects an error of transmission data included in the divided transmission data by using the extracted error detection information in order to identify a transmission path in which the error of transmission data has occurred, and stops the transmission path.
