SYNCHRONIZATION DETECTING METHOD AND SYNCHRONIZATION DETECTING CIRCUIT |
摘要 |
A synchronization detecting circuit detects a synchronous signal from a reproduced signal of a recording medium in which a random shift method is employed. A window generator in the synchronization detecting circuit generates a third window having as a central phase one predicted phase in a second predicted coordinate that is obtained by replicating a first predicted coordinate indicating a predicted phase of each synchronous signal that repeatedly appears in the reproduced signal and having a phase width equivalent to twice a random shift width when the synchronous signal is not detected using a first window after the synchronous signal is detected using a second window by a synchronization detector. |
