DVB-H receiver for forward error correction and method thereof
Abstract:
A DVB-H receiver for performing forward error correction is disclosed. The DVB-H receiver includes: a tuner, for receiving a data stream; a base-band receiver, coupled to the tuner, for continuously extracting and transmitting data bytes of an MPE-FEC frame from the data stream; a backend system, coupled to the base-band receiver, for generating corresponding syndromes of the extracted data bytes once all data bytes of the MPE-FEC frame are received, outputting the syndromes to the base-band receiver, and forward error correcting the MPE-FEC frame according to error values corresponding to the syndromes; and a storage device, coupled to the backend system, for storing the extracted data bytes. The base-band receiver generates the error values and error locations according to the received syndromes, and then outputs the error values and error locations to the backend system.
