PROBLEM TO BE SOLVED: To provide a synchronization recovery system in which a probability of causing false synchronization is reduced with respect to serial data arranged by adding respective synchronizing signals to plural packets. SOLUTION: A transmitter side adds a specific synchronization pattern to the head of each packet of serial data while inverting the pattern in each packet. A synchronization pattern comparison means 15c in a synchronization recovery device 15 is at a receiver side compares the synchronization pattern of the serial data with the synchronization pattern stored in advance in a synchronization pattern storage means 15a and allows a pulse signal generating means 15f to generate a pulse signal equivalent to a period up to a time corresponding to a packet length from a coincident timing when they are coincident. The pulse signal is compared with a coincident signal from the synchronization pattern comparison means 15c, and when they are coincident, coincident information is outputted as a synchronizing signal and the synchronization pattern read from the synchronization pattern storage means 15a is inverted. |
