Patent ID: 8638823

Claim:
A receiving apparatus for receiving a transmission frame that is sent via a network, the transmission frame including header information, a payload, and FEC (Forward Error Correction) data, the header information including a first synchronization signal and a second synchronization signal, and the FEC data being data for correcting an error in a portion other than the first synchronization signal in the header information and in the payload, the receiving apparatus comprising, a synchronization establishing unit configured to establish frame synchronization by detecting the first synchronization signal in the header information of the transmission frame, an FEC execution unit configured to execute error correction in the header information and in the payload, by using the FEC data within the transmission frame, after the synchronization establishing unit has established the frame synchronization, an out-of-synchronization monitor configured to make a judgment whether or not the frame synchronization is maintained, by determining whether or not the second synchronization signal included in the header information having been subjected to the error correction by the FEC execution unit matches a signal pattern being predetermined, and a data output unit configured to extract the payload within the transmission frame when the out-of-synchronization monitor determines that the frame synchronization is maintained, and output the payload to an external device.
