Abrégé : front page image
(EN)A method of, and apparatus for, encoding a serial stream of digital data blocks (characters) comprises partitioning the stream into the data blocks; translating the blocks into corresponding encoded equivalents; and assembling the encoded equivalents together to generate an output serial stream of encoded data. The method is characterised in that; each encoded equivalent includes equal numbers of logic O's and logic 1's; the encoded equivalents are mutually distinguishable such that a single bit error in one or more of the equivalents is unambiguously detectable; each value of data block uniquely maps onto a corresponding encoded equivalent and at least one equivalent is a marker equivalent for which is periodically inserted in the output stream to denoting where equivalents occur in the output encoded data. The method of encoding data provides the benefit of addressing issues of synchronisation, reducing bit error rate, and balance simultaneously.
