Abstract
PURPOSE:To enable a synchronizing signal to be stably fetched even when high speed searching or the like is executed by canceling a window with the aid of the command of an operation mode where the synchronizing signal cannot be continuously obtained in a prescribed cycle. CONSTITUTION:When the command of the high speed searching is given, an AND circuit 12 can be operated through an OR circuit 33, the synchronization detection window is always in a releasing state and all synchronization detection signals are fetched. That means, the window is released by the command of the operation mode without waiting the synchronizing signal is off from the window similar to a conventional circuit. As the result, the window releasing can be executed at once. Thus the synchronizing signal can be relatively stably fetched even when the high speed searching is executed.
