ABSTRACT:
A method for encoding data packets includes providing an encoding scheme for coding source data units into encoded data units; establishing a first look-ahead table for the source data units; providing a data packet including a first source data unit and a second source data unit; encoding the first source data unit to generate a first encoded data unit; indexing the first look-ahead table using the first source data unit to determine a balancing capability of the first encoded data unit for balancing a running disparity; and encoding the second source data unit to generate a second encoded data unit using the balancing capability of the first encoded data unit.
