ABSTRACT:
An apparatus and method for transmission of data. A four bit data word is converted into an eight bit code word having a run-length of (0,1) which includes four binary ones and four binary zeros is defined where the start and end bits comprise a 01 or 10 pair to ensure the (1,0) run-length across word boundaries. A hashing code is used to generate the code words and decode received code words.
