<p>PROBLEM TO BE SOLVED: To improve capacity for detecting the lack/double reading of a vertical bit string, which occurs at the transmission of a parallel data signal 5. SOLUTION: An error monitoring signal line is povided, and the signal is transmitted by permitting a monitoring frame 12 consisting of a monitoring header 10 and a monitoring payload 11 to synchronize with a data frame 9. The monitoring header 10 is provided with error detection information obtained from the vertical parity of the parallel data signal 5. The monitoring payload 11 is the vertical parity of the data payload part of the parallel data signal 5 and it detects an error synchronized in the respective signals of the parallel data signals 5 by using the monitoring frame 12.</p> |
