Abstract
Detection of synchronization signals of digital broadcasting waves of respective reception systems is periodically carried out, and a relative time difference between synchronization timings of the synchronization signals is grasped. In the case where a synchronization signal can not be detected from the reception system under selection, the relative value is added to or subtracted from the generation timing of a synchronization signal of the other reception system, so that the synchronization timing that could not be detected is presumed.
