摘要:
A time information acquiring apparatus includes: a first decoder (20, S13) which decodes a time code signal frame by frame so as to generate solo-decoded time information; a first determining section (20, S20, S21) which determines consistency of the solo-decoded time information; a second decoder (20, S16) which combines detection data of the frames, and performs a code determination on the time code signal based on the combined detection data so as to generate sum-up-decoded time information; a second determining section (20, S20, S21) which determines the consistency of the sum-up-decoded time information; and a controller (20, S5) which makes the first decoder generate the solo-decoded time information, the first determining section determine the consistency of the solo-decoded time information, the second decoder generate the sum-up decoded time information, and the second determining section determine the consistency of the sum-up-decoded time information in a predetermined order so as to extract time information having the consistency.
