碩士 === 國立臺北科技大學 === 資訊工程系所 === 98 === IP-based wireless technology has been developed very rapidly in recent years. With high-speed bandwidth, high-definition video and mobile internet services, this technology can even fulfill consumer’s high-quality television service requirement at anytime and any place. Therefore, the European Digital Video Broadcasting Technology Development Organization (Digital Video Broadcast Project, DVB Project) proposed the DVB-Handheld (DVB-H) technologies. In this thesis, we aim to implement the software modules of network and transport layers specified by the IP Datacast Protocols. The carried out tasks include:(1) Decapsulation of FULTE/ACT/LCT packets; (2) Realization of the Forward Error Control (FEC) mechanism with Compact No-Code scheme; (3) Parsing the Electronic Service Guide (ESG) data for further processing in the corresponding application layers; (4) Parsing the Session Description Protocol (SDP) data; (5) Decoding the LCT extension field, which includes the authentication data, FDT instance header (EXT_FDT) and FEC object transmission information (EXT_FTI); (6) Decapsulation of RTP/RTCP packets for further decoding in the corresponding video and audio modules to complete the network and transport layer software modules for a DVB-H reception system. After the decapsulation of RTP / RTCP packets, streaming live video and audio contents are sent to the corresponding application layer decoding modules correctly and efficiently. Furthermore, through the decapsulation of FLUTE / ALC / LCT packets, the file based data and ESG information are sent to corresponding application layer modules for further decoding or interpretation. The results of this research work can be integrated with other DVB-H modules to realize a complete DVB-H reception system.
