ABSTRACT:
A method and apparatus for transmitting data blocks, each data block representing one of a plurality of characters, between a transmitting station and a receiving station of a distributed processing system. The characters are encoded in the transmitting station according to a code set so that each transmitted data block has an equal number binary ones and zeroes and a distance of at least four. The code is self-clocking and allows one bit error correction and AC coupling.
