Abstract
A Digitally Video Broadcasting—Handheld (DVB-H) system for performing forward error correction includes: a tuner for receiving a data stream; a base-band receiver, coupled to the tuner, for extracting data bytes of a multi-protocol-encapsulation forward-error-correction (MPE-FEC) frame, and performing syndrome calculation on each extracted data byte to determine a corresponding partial syndrome; and an embedded memory, coupled to the base-band receiver, for accumulating each partial syndrome to determine a complete syndrome; wherein once all syndromes of the MPE-FEC frame are received, the base-band receiver determines corresponding error values and utilizes the error values to forward error correct the MPE-FEC frame.
