Information detecting apparatus and method
Proposed is a highly reliable information detecting apparatus and method. In an information detecting apparatus and method for detecting transmission information a transmission signal in which a burst period of transmitting a burst signal and a space period as a no-signal period are repeated in a pattern according to the subject matter of the transmission information, whether the absolute value of a signal amplitude level of the transmission signal is not less than a first threshold is detected, whether the absolute value of a signal amplitude level of the transmission signal is not less than a second threshold is detected, and whether the amplitude level displacement of the transmission signal is based on noise or the reception of the transmission information is determined based on the detection results.
