Abstract
An original code series containing a synchronizing code is divided into code series, n in number so as to reduce an operation rate to 1/n (n is a positive integer). The detection of a synchronizing pattern is conducted on the basis of a fact that an original synchronizing pattern is transformed into any of patterns of n kinds based on the phase of division.
