    Abstract: 在寬頻高速網路環境下,人們使用著各式各樣的消費性、網路電子產品來取得多樣的影音媒體服務及應用。隨著使用者擁有多個不同種類的影音裝置,影音檔案存放在不同的裝置上,不同廠牌的裝置間使用不同的網路檔案傳輸方式、檔案格式及呈現方式,使得裝置間無法互相分享並播放多媒體檔案。為了成功地讓多媒體裝置播放儲存在其他裝置上的多媒體檔案,使用者必須在各個裝置上安裝檔案傳輸的應用程式,或是利用其他儲存媒介來移動、傳遞檔案。然而,受限於各類裝置軟硬體架構的可擴充性與否,很可能無法使用上述方法進行分享,且這類複雜的操作不符合使用效益。
    ;People in pervasive broadband networks can access various kinds of media services with modern consumer electronics in residential environments. When they intent to share media content stored in different devices, they often fail to play or access any media items due to the incompatible issues of network transport, media type, and presentation formats between media devices. To successfully render the media content as wished, users may have to manually change device settings, configurations, and functionalities both in hardware and software, which is complicated to many users.
    The study of this thesis proposes an integrated design of a service-oriented platform and controlling mechanisms for enabling multimedia and streaming services across different media devices in managed home networks. This design consists of four major components: (i) a media controller for controlling media devices, (ii) a convergence server of publishing and representing content, (iii) a device discovery manager for discovering and monitoring devices in a local network, and (iv) a transformation engine of enabling Internet media streaming and playback in a home network. The development of the proposed design follows the interoperability specifications guided by Universal Plug and Play (UPnP) Forum and Digital Living Network Alliance (DLNA) that are aimed for the standards of home AV entertainment on modern home-networked devices.
    The implementation of the proposed design provides a proof-of-concept application system that integrates UPnP protocol stacks, partial DLNA specifications and FFmpeg libraries on Android operating systems. Practical demonstration shows the scenarios, and evaluates the performance of the proposed system. Consequently, the effort of this study offers users a friendly and networked operational solution. Users are now able to enjoy various multimedia contents from internal and external networks with many off-the-self home-networked devices as well as handheld devices in home network environments.
