Abstract:
1. A method of transmitting a timecode for simultaneously transmitting correlated LTC (Linear Time Code) and VITC (Vertical Interval Time Code) comprising: as a pre-processing step when transmitting a timecode, a step of retrieving a checking information from the LTC and creating a checking data using the retrieved checking information; and a step of superimposing the checking data on the VITC; as a post-processing step after having received a timecode, a step of retrieving a collating information corresponding to the checking information from the received LTC to create a collating data using the retrieved collating information; and a step of retrieving the checking data from the received VITC and collating the retrieved checking data with the collating data to verify the presence or absence of errors in the received LTC.
