Abstract

See full text

Methods and apparatus for the intelligent association of control symbols with special symbols that are transmitted over a network. In one embodiment, the association is utilized to improve DC-balance on a transmission medium. In an exemplary variant, the special symbols originate from line codes such as the 8B/10B line code, which format a digital signal so that is optimized for transmission over a given physical channel. These control symbols are divided up according to a first criterion, while the special symbols are further divided up according to a second criterion. The divided control symbols are then allocated to the divided special symbols using a pre-designated allocation algorithm, which may or may not include a scrambling algorithm. The allocation of the control symbols improves signal characteristics and electromagnetic interference (EMI) when various ones of control symbols are ultimately transmitted over a given transmission medium.
