Frame synchronous pattern processing apparatus and frame synchronous pattern detection apparatus and method for detecting frame synchronous pattern

摘要

The invention concerns a technology for detecting a frame synchronous pattern comprising: a data switch section for performing a data rearrangement processing of parallel data having a given frame synchronous pattern; a temporary region detection section for temporarily detecting a candidate of region data containing the frame synchronous pattern from the parallel data; a frame synchronous pattern detection section for detecting the frame synchronous pattern from the temporary region data of the temporary region detection section; and a data switch control section for controlling data rearrangement processing by the data switch section according to the detection state of the temporary region data by the temporary region detection section and to the detection state of the frame synchronous pattern by the frame synchronous pattern detection section, in order to detect precisely the frame synchronous pattern in m parallel data without enabling the detection of m ways of frame synchronous patterns in m parallel data.
