整合P2P與UPnP內容分享服務之家用多媒體閘道器：設計與實作

先進家庭網路技術的建置能將不同的網路多媒體裝置 (例如：個人電腦、手持裝置或電玩主機) 在居家環境中互相連接而提供嶄新的家庭網路應用與服務，其中家庭多媒體娛樂在現代家庭網路環境中佔有極重要的一席之地。有別於傳統家庭多媒體內容分享情境—僅能分享區域網路之內容並需經由繁瑣的連線、檔案傳輸設定之方式，本篇論文呈現一利用網路之方式達到能使具有網路功能之裝置自動發現鄰近裝置並分享豐富的網路多媒體資訊。為達到此理想情境，本篇提出創新的家庭多媒體內容分享架構整合數項特殊機制包含—裝置發現、家庭網路閘道器、網際網路多媒體提供和家庭網路內之多媒體共享。本設計主要專注於克服裝置間固有的異質性與家庭網路與公共網路間之共通性達到使網路裝置撥放多媒體內容方式之一致性。軟體實作原型整合了BitTorrent P2P客戶端、UPnP通訊協定、UPnP AV多媒體伺服器、多媒體散佈與管理元件於OSGi家庭多媒體閘道器平台中。實作成果設計與展示為家庭多媒體娛樂提供更佳的使用者經驗與無限制的多媒體內容。

The deployment of advanced home networking technologies connect a variety of modern networked and multimedia devices, e.g., desktops, mobile phones and game consoles, in a residential area, providing a playground for new home applications and services. Since home multimedia entertainment is one of important home applications, this paper presents a home media content sharing scenario in which networked devices can discover neighboring devices and share enormous Internet media content in a convenient, networked manner. This ideal scenario differs from the traditional cases which merely offer local media content and require tedious manual operations of connection setup and file transfer. To achieve this goal, this study proposes a novel home multimedia content distribution rchitecture for home network environments. The proposed architecture integrates several specific mechanisms,including device discovery, home gateway,Internet media provision, and in-home media content delivery.This design addresses several inherent limitations of device heterogeneity and network interoperability in home and public networks, and allow networked devices to play media content in an identical,networked way. This study develops a proof-of-concept software prototype,integrating BitTorrent peer-to-peer client, UPnP protocol stack, UPnP AV media server, and media distribution and management components on the OSGi home gateway platform. Practical demonstration shows the proposed design and scenarios, achieving not only better user experience but also an unlimited volume of media content for home multimedia entertainment.
