隨著網路技術的進步，多媒體應用也越來越多元化，但是目前大部分多媒體伺服器所支援的用戶端，其硬體平台仍然侷限於個人電腦上，缺少可攜性與方便性。因此若能將伺服器所服務的範圍擴展到手持式行動裝置上，並配合無線網路技術的應用，就能讓使用者隨時隨地享受影音串流服務。
目前在手持式行動裝置上的播放軟體大部分都採用標準RTP網路協定，其中RealNetworks的Real Player是普及率相當高的軟體，因此本論文使用網路上公開的軟體Fenice，修改網路協定使其可以支援Real Player的溝通方式，並加上3GP檔案串流機制以及即時影音壓縮功能，讓使用者可以利用手機內建的Real Player來播放影片。
本論文首先描述RealNetworks相關的串流傳輸通訊協定，以及Fenice原始架構，接著依照GPRS無線網路的特性來設計串流傳輸機制，並實作3GP檔案解析器與即時影音同步機制，最後再驗證及分析本論文所設計之伺服器。

With the improvement of network technology, the applications of multimedia streaming became diverse. Over recent years, the majority of streaming server only supports the client executed on the personal computer, and lacks of portability and convenience. If a streaming server can offer a service for mobile devices, then users can enjoy multimedia service anytime and anywhere.
Real Player published by RealNetworks is a very popular software among the players of mobile devices nowadays. So, we modify the protocol of free software, Fenice, for supporting Real Player’s communication protocol. In addition, we implement a 3GP file parser, and design an A/V streaming mechanism in order to provide more services based on Real Player.
This thesis first describes streaming protocol related to RealNetworks and the original architecture of Fenice. Then we design the data transmission mechanism for GPRS mobile communication. We also implement 3GP file parser and real-time A/V synchronization mechanism. Finally we test and analyze the validation of the designed server.
