초록

We present a powerful error control decoder which can be used in all of the commercial DVD systems. The decoder exploits the error information from the modulation decoder in order to increase the error correcting capability. We can identify that the modulation decoder in DVD system can detect errors more than $60\%$ of total errors when burst errors are occurred. In results, fur a decoded block, error correcting capability of the proposed scheme is improved up to $25\%$ more than that of the original error control decoder. In addition, the more the burst error length is increased, the better the decoder performance. Also, a pipeline-balanced RSPC decoder with a low hardware complexity is designed to maximize the throughput. The maximum throughput of the RSPC decoder is 740Mbps@100MHz and the number of gate counts is 20.3K for RS (182, 172, 11) decoder and 30.7K for RS (208, 192, 17) decoder, respectively
