A data encoding system for a data stream comprises a data dependent scrambler that receives the data stream including K m-bit symbols, that selects a seed based on the K m-bit symbols, that scrambles the K m-bit symbols using the seed and that outputs a codeword including the scrambled K m-bit symbols and the seed. A DC control module receives a plurality of the codewords from the data dependent scrambler, selectively inverts selected ones of the plurality of codewords to reduce a difference between a total number of zeroes and total number of ones in the plurality of codewords and outputs an encoded data stream.
