ABSTRACT:
The present invention comprises the step of reading a check-receiving data included in a transmitted time code signal and using the read check-receiving data to generate a transmitting side checking data, and the step of attaching the transmitting side checking data to the transmitted time code signal, as a pre-processing step at the time of transmitting the time code signal. The present invention comprises the step of reading the check-receiving data from the received time code signal and using the read check-receiving data to generate a receiving side checking data, and the step of reading the transmitting side checking data from the received time code signal and comparing the read transmitting side checking data to the receiving side checking data, thereby verifying whether or not an error is generated in the received time code signal. In this way, an error can be detected in the time code signal, as a post-processing step after the time code signal is received.
