Method and system for detecting user data types in digital communications channels and optimizing encoding-error correction in response thereto

摘要

A dynamic error correction system for a digital data transmission system. A transmitter adapted to encode user data into a signal is included within the system. A receiver receives the signal and decodes the user data encoded thereon. The signal is transmitted from the transmitter to the receiver via a communications channel. A data type detector is coupled to the transmitter. The data type detector is adapted to detect a data type of the user data being coupled to the transmitter for transmission via the communications channel. A processor is coupled to the transmitter and is adapted to implement at least a first error correction process and a second error correction process for the transmitter, wherein the second error correction process is of a higher capability than the first error correction process. The processor is coupled to receive the data type from the data type detector and dynamically select the first error correction process or the second error correction process in response thereto such that error correction employed by the transmitter is best suited to the data type of the user data.
