Patent ID: 7492846

Claim:
A standard wave receiver for receiving a standard wave including a time code signal, in which one frame including plural time codes is repeated, and decoding the time codes, comprising: a sampled value sequence accumulating unit that samples the time code signal over a period in which a plurality of the frames continue and accumulates sampled value sequences including plural sampled values generated in time series; a marker position determining unit that convolutionally adds the sampled value sequences every predicted period of a marker code indicating a leading position of the frame to generate an added value sequence and determines a position of the marker code on the basis of the added value sequence; a time code position determining unit that determines positions of the respective plural time codes in accordance with the determined position of the marker code; and a time code determining unit that, for each of the time codes, extracts partial sampled value sequences, which corresponds to a position of the time code and is expected to take an identical value, out of the sampled value sequences, convolutionally adds the partial sampled value sequences to generate an added value sequence, and determines a value of the time code on the basis of the added value sequence.
