Abstract:
A method of communicating information between a transmitting entity and a receiving entity, each of which are operative to communicate a bit stream that includes a parity bit for detecting errors in the bit stream, the method comprising the steps of:generating a bit stream from the information, the bit stream including a parity bit;communicating the generated bit stream from the transmitting entity to the receiving entity;performing a parity error analysis on said communicated bit stream; andparsing the communicated bit stream according to a parsing process selected based on said parity error analysis to provide an uncorrected communicated bit stream, wherein said step of parsing comprises the steps of:parsing said communicated bit stream using a first first parsing process slected from a plurality of predetermined parsing processes based on said parity error analysis performed on said communicated bit stream; anddetecting a toggle flag within said communicated bit stream, wherein said step of detecting comprises the steps of:determining whether said toggle flag is followed by an additional toggle flag; andswitching said receiving entity to an expanded mode if said toggle flag is not followed by said additional toggle flag; andparsing a subsequent communicated bit stream using a second parsing process selected from said plurality of predetermined parsing processes based on said parity error analysis performed on said subsequent communicated bit stream.
