碩士 === 國立臺北科技大學 === 電腦與通訊研究所 === 98 === In this paper, we discuss how to improve performance of decoding method in Digital Video Broadcasting-Handheld (DVB-H) Link Layer. We use uniform channel, Markov channel, and measurement channel as the simulation environment. The DVB-H standard suggest that section erased or not according to result of Cyclic Redundancy Check (CRC). So, we proposed to Transport Stream Erasure Decoding (TSED) algorithms that Transport Stream (TS) packet erased or not according to Transport Error Indicator (TEI). Finally, we compare to performance of decoding methods and find which length of Internet Protocol (IP) packet can get maximum data rate in different channel.
