Abstract
A system and method for transmitting digital data over a transmission medium includes receiving digital values representing a plurality of N-bit characters to be output over the transmission medium, each N-bit character being either a data character or a control character. A determination is made as to which of the plurality of N-bit characters are control characters. The digital values represented by the plurality of N-bit characters are encoded to provide an encoded codeword, the encoded codeword being {M×(N−1)+P} bits having M fields of N−1 bits, each of the M fields corresponding to one of the N-bit characters being encoded. The encoding further includes: designating, for each data character, the respective field of the M fields as a data field, designating, for each control character, the respective field of the M fields as a control field, and ordering the M fields to position any control fields at predetermined positions with respect to each other in the encoded codeword and to position any data fields at other remaining positions within the encoded codeword. The encoded codeword is then transmitted over the transmission medium. A system and method that receives such an enco…
