Abstract:
1. A time reception apparatus comprising: a reception unit to receive a standard frequency broadcast including time information composed of a plurality of pieces of data divided into every second; a waveform shaping unit to perform waveform shaping of the standard frequency broadcast received by the reception unit to a time code signal expressed by binaries divided into every second; a change time calculation unit to detect a change point at which the time code signal subjected to the waveform shaping by the waveform shaping unit changes in a divided period, and to calculate a time from a start of the period to the change point; a decoding unit to judge data in the period divided into a second based on the time calculated by the change time calculation unit, so as to decode the time code signal subjected to the waveform shaping by the waveform shaping unit; and a time extracting unit to extract a time indicated by the time information in accordance with a decoded result by the decoding unit.
