Summary:PURPOSE:To improve the efficiency of data and signal transmission by inserting a synchronizing code, then inserting the next synchronizing signal after a byte being the difference between the number of maximum bytes of a minimum synchronizing block and the number of maximum bytes of a data block. CONSTITUTION:The synchronizing code is added at first to a synchronizing code area 1', the byte number of the synchronizing code is added and then the number of bytes of the data block group is counted. When the count number (n) is within a range of Equation at the end of count, the count number is cleared and the synchronizing code 2' is inserted, where (m) is the maximum number of bytes in which the data block can reach, Nm is the maximum number of bytes in which the synchronizing block can reach, (j) is the number of data blocks in the synchronizing block, and Ni is the number of bytes in each data block. Thus, the synchronizing code has only to be inserted after (Nm-m)/2-set of data blocks in transmitting the data of 1-byte.
