Error correction encoding a data stream of information

摘要

An apparatus and method for error correction encoding a datastream of information into blocks of error correction encoded information. An input terminal receives the datastream. An error correction encoding unit performs an error correction encoding on portions of the datastream. A block of error correction encoded information includes n sync blocks, each sync block including a sync word and a portion of the error correction encoded information, where n exceeds 3. An output terminal supplies the blocks of error correction encoded information. The error correction encoding unit supplies one of m mutually different sync words to each n sync block, such that the sequence of two sync words of corresponding two sync blocks of the n sync blocks is unique with respect to the bit patterns within the two sync words, m satisfying 2
