Abstract:
1. A synchronization signal detecting apparatus, comprising: a synchronization detecting circuit for detecting a synchronization signal from an input bit stream in a first window and detecting the synchronization signal from the input bit stream in a second window different from the first window; and a control circuit, wherein, if the synchronization signal is not detected by said synchronization detecting circuit in the first window in a state in which the second window has been set to a prescribed time interval in a time range that excludes the first window, and the synchronization signal is detected by said synchronization detecting circuit in the second window a predetermined prescribed number of times in succession in accordance with a predetermined synchronization period, said control circuit exercises control for re-synchronization established to generate the first window periodically in accordance with the synchronization period using a detection position of the synchronization signal in the second window as a reference.
