Abstract
A method and apparatus to encode data is provided. The method includes the steps of: i) dividing the data into a plurality of blocks, with each block having a plurality of bits, wherein the plurality of blocks includes a first subset of blocks and a second subset of blocks; ii) encoding data in the first subset; arranging a codeword to include the encoded data of the first subset and the second subset; iii) scanning a plurality of segments in the codeword for at least one predetermined sequence; and iv) encoding a scanned segment when the predetermined sequence is found in the segment. A method and apparatus to decode data is also provided according to the present invention.
