Abstract:
1. A time code discrimination apparatus that discriminates a time code including one-minute digit and ten-minute digit codes, the time code discrimination apparatus comprising: a waveform data acquiring section to acquire waveform data of the one-minute digit code arranged at a predetermined position in a format of the time code of a standard radio wave; a first code acquiring section to acquire the waveform data of a plurality of sets of one-minute digit codes, which are acquired by the waveform data acquiring section, a predetermined number of times at a time interval of one minute; a comparison section to compare (i) the waveform data of the plurality of sets of one-minute digit codes acquired by the first code acquiring section with (ii) reference data indicating waveform data of an original one-minute digit code while shifting comparison positions; a comparison position indication section that indicates a comparison position of (i) the waveform data of the plurality of sets of one-minute digit codes and (ii) the reference data; and a first code discrimination section to detect which position in the reference data the waveform data of the plurality of sets of one-minute digit codes correspond to, and to discriminate the waveform data of the plurality of sets of one-minute digit codes based on the comparison position indicated by the comparison position indication section, when it is determined by a result from the comparison section that the waveform data of the plurality of sets of one-minute digit codes matches the reference data.
