摘要

隨著網路科技廣泛的使用，與無所不在的各種掌上型電子用品與嵌入式裝置，數位家庭已經變成一個融入居家環境，集合各種網路相連設備交換多媒體資料之具體情境與娛樂中心。由於人類對居家娛樂之強烈需求，促使網際網路的應用從單純的網頁瀏覽能延伸至銜接數位家庭中各種不同功能及媒體格式之重要橋樑。然而，如此的轉變是非常的平順且相容於目前已存在的技術，除了重複利用大部分的OSI-ISO網路架構做為數位家庭網路技術的基礎，各研究單位及業界亦提出相關的協定與技術，包含服務的找尋與協同工作、計時、壅塞控制、與串流的服務品質。

在數位家庭中有一個很重要的協定是通用即插即用協定(Universal Plug and Play)，其主要是負責確保不同種類設備之間的互通性，以解決這些設備之間的整合。在本論文中，我們將利用英特爾（Intel）所發展的工具，依據英特爾所公佈之多媒體伺服器架構，來建立一個數位家庭中很重要的多媒體伺服器雛形，並且使用英特爾的模擬工具（如Device Monitor, AV Media Controller等）來模擬未來數位家庭的環境。從我們的模擬環境中，我們深信數位家庭的願景將在不久的將來發生在我們的生活周遭，大大地使我們的生活更加便利。

With the wide adoption of Internet technology and massive penetration of all types of handheld equipments and embedded systems, digital home has risen for converging several network-connected devices in delivering media entertainment in a home environment. The evolution of WWW from browsing websites to connecting different devices in the digital home is mainly driven by the strong demand of home entertainment. Surprisingly, such transition is quite smooth and compatible to existing technology. Most of the OSI-ISO layers are reused as the underlying protocols and some additional protocols are introduced to address services discovery and collaboration, timing, congestion control, Quality of Service (QoS) concerned found in digital home streaming.
One of the substantial protocols employed in digital home is the Universal Plug and Play (UPnP) protocol, which is mainly responsible for assuring the interoperability of various kinds of devices and hence facilitating possible integration of components. In this thesis, we will introduce the UPnP protocol and technology with tool kits from Intel are highly leveraged to build a prototype media server, which was adopted from Intel’s sample Digital Media Server (DMS). The implementation is then tested and evaluated with external UPnP control points such as Device Monitor and AV Media Controller from Intel technology. Additionally, we will share the experience from building the media server, and show the evaluation results.
