Abstract
A transmitter communicates with a receiver and an error corrector corrects bit errors generated during data transmission. The transmitter has a scrambler unit that scrambles data so that a running disparity of 0 and 1 in the input data is substantially zero. A bit-string converting unitthat adds bit data for ensuring a maximum run length of a serial bit string of the scrambled data and converts control information to bit data of a fixed value. A synchronization timing generating unitdivides the transmitted data by a constant interval and converts the transmission data to a data block. A bit-string converting unit extracts a fixed-value bit pattern of the control data from the bit string of the data block, converts the bit pattern to the control information, and discriminates the data and the control information. A descrambler unit reconverts the data-scrambled data to the data before scrambling.
