Abstract: PROBLEM TO BE SOLVED: To provide nB2P encoder and decoder to simultaneously provide a line code function and a channel code function in a transmission line and a link. SOLUTION: An nB2P encoder divides inputted parallel data into a fixed data unit, converts data that is encoded by adding an odd parity to each divided data unit and a block synchronizing signal that is set by preliminarily making the encoded data perform code violation into serial data through a selection signal and outputs it. The nB2P encoder detects a block synchronizing signal by using a code violation pattern that is preliminarily set, converts encoded data into parallel data through a byte timing, detects an error of encoded data by checking an odd parity and decodes it into original data by eliminating the parity.
