Methods and apparatus for the intelligent association of control symbols
First Claim
1. An apparatus configured to receive media according to one or more transmitted control functions, the apparatus comprising:
- a receiver configured to receive one or more control codes associated with one or more corresponding control functions, at least one of the one or more control codes being dynamically encoded; and
logic in communication with the receiver and configured to determine a corresponding control function for each control code of the received one or more control codes, the logic configured to;
determine whether the each control code comprises a dynamically encoded control code or a non-encoded control code;
decode the dynamically encoded control code based on one or more contents of a linear feedback shift register (LFSR);
identify a corresponding control function from the decoded control code based on a look-up table; and
identify a corresponding fixed control function based on the non-encoded control code;
wherein the received one or more control codes are divided into a first group and a second group based on a different frequency of use of respective ones of the received one or more control codes.

Abstract
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.
