Abstract
To obtain unique identification data to be added to program data even if different encoders are used, identification data generated by adding serial data specific to an encoder to data (time code) indicating the time of encoding is inserted into program data to be stored in a storage device. Whether the program data has been transmitted is checked based on the thus-generated identification data. By virtue of the use of such an identification data, even if program data are produced at the same time point by using different encoders, they can be clearly distinguished from each other because they are associated with different identification data because serial data of the encoders are different.
