Abstract:
1. A block encoding method, comprising steps of: determining whether an original block of m bits is a (2N−1) st block of m bits, “m” and N being positive integers; and encoding, if the original block of m bits is the (2N−1) st block of m bits, the original block of m bits as an A type weighted block of n bits having a preselected number of “1” bits and “0” bits and, if otherwise, encoding the original block of m bits as a B type weighted block of n bits 7 having another pre-selected number of “1” bits and “0” bits where “n” being an odd integer larger than “m”, wherein both A type weighted block and its corresponding B type weighted block are combined to form a balance coding block in which the bit number of “1” is equal to that of “0”.
