Abstract:
A dynamic error correction system for a bi-directional digital data transmission system, comprising:a transmitter adapted to encode information into a signal;a receiver adapted to receive said signal and decode said information encoded thereon, wherein said signal is transmitted from said transmitter to said receiver via a communications channel;an error rate detector coupled to said receiver, said error rate detector adapted to detect an error rate in said information transmitted from said transmitter;a processor coupled to said receiver, said processor adapted to implement at least a first error correction process and a second error correction process for said receiver, wherein said second error correction process is of a higher capability than said first error correction process; andsaid processor coupled to receive said error rate from said receiver via a feedback channel within said communications channel and dynamically select said first error correction process or said second error correction process in response thereto such that error correction employed by said receiver matches the condition of said communications channel, said receiver adapted to use said second error correction process to decode information on said communication channel while said transmitter uses said first error correction process to decode information on said feedback channel.
