Error detection in a network device

摘要

In a system, a data receiving device (11b) comprises a timing signal generation unit (34) that generates a timing signal used for receiving the divided transmission data in each of the transmission paths, a data receiving unit (31, 34) 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 (34 - 38) that extracts the error detection information from the divided transmission data received for each of the transmission paths by the data receiving unit and detects an error of transmission data included in the divided transmission data by using the extracted error detection information.
