近年來由於電腦軟硬體設備的進步與多媒體技術的蓬勃發展,使得多媒體應用在生活中越來越普及,而使用者與影片資料量也越來越多,影片資料之管理也日漸重要。因此影片儲存庫之實現,方便使用者查詢並擷取影片資料。因此如何妥善管理及規劃影片資源是影片資源管理系統建置的重要探討議題。 本研究透過語意網(Semantic Web)的技術,以及依據XML檔案本身具有結構性的特性,以原生型XML資料庫(eXist)來儲存紀錄影音資訊的XML檔案,並將RDF/OWL技術,運用在以XML檔案文件為主的eXist資料庫上,如此可以將XML文件,作更加有效的管理。使用者可以利用我們所建立的影音平台上,使用OWL/RDF這個文件,將XML儲存庫中的資料做樹狀式的儲存,如此可以使得資料彼此之間具有一定的相關程度,讓使用者可以達到便利影片查詢的目的。本研究也利用XQuery的查詢語言,可對XML資料的結構作查詢,能更有效率查詢到XML資料中每個標籤的內容。除此之外,本研究結合同步多媒體集成語言(SMIL),提供豐富的多媒體資訊整合,我們利用其可控制多媒體的特點,在影音廣播伺服器中建立可排程的網路影音廣播系統,達成影音排程之規劃,將廣播伺服器所產生之多媒體串流,導入CDN串流伺服器,使多媒體內容能以CDN機制傳播給更多瀏覽者觀看。
Due to the advance of computer technology and the rapid growth of multimedia applications, a huge quantity of video contents are available for browsing in our daily life. Management of video clips in proper classification schema is becoming more important. Therefore, the development of video content management registry/reposit- ory(VCMRR) which aims at providing a friendly user-interface and an efficient retrieval mechanism is an urgent issue. In this thesis, we attempt to use Semantic Web and native XML-based database (eXist) to enrich the capability of VCMRR. We proposed using RDF/OWL documents to depict video contents and storing them in the eXist database. Users can create the RDF/OWL document for a newly uploaded video clip. This enables users to describe the video contents in more effective and intelligent way. Our system also facilities the search of video contents using XQuery and RDF/OWL. Moreover, we also integrate Synchronized Multimedia Integration Language (SMIL) and Windows Media Server (WMS) in our VCMRR. It not only supports on-demand and broadcast mode to watch the video contents but also enables users to schedule their playing list whatever they want. In order to provide more viewers for internet video broadcasting services, Our system can integrate with Peer-to-Peer broadcast server and form an efficient Content Delivery Network(CDN) for streaming services.
