Abstract:
1. A hyperframe synchronization processing apparatus for establishing synchronization of a hyperframe which has a plurality of first frame groups each including one or a plurality of first frames and a plurality of second frame groups each including one or a plurality of second frames distinguishable from the first frames and in which the first frame groups and the second frame groups appear alternately, the hyperframe synchronization processing apparatus comprising: a difference calculator configured to calculate differences between the number of the first frames included in the respective first frame groups and the number of the second frames included in the respective second frame groups which follow these respective first frame groups in the received hyperframe; a storage configured to sequentially store the differences calculated by the difference calculator; and a synchronizer configured to establish the synchronization of the hyperframe by using the differences stored in the storage.
