基於ASP的VOD視訊服務器的設計
摘 要 ：近年來，Intemet有了蓬勃的發展。1方面，主幹網和接入網速率不斷提高，為各種寬頻應用提供了必需的硬體基礎設施;另1方面，越來越多的人願意互動式地觀看音視訊節目，這1切都為視訊點播技術的發展創造了良好的條件。VOD即視訊點播是利用視訊伺服器儲存視訊節目和其它多媒體資訊，通過傳輸網路和客戶端裝置向用戶提供互動式視訊服務的系統。其中視訊伺服器是VOD系統的核心，它的穩定程度和效能，關係到整個系統的`效能。當前的視訊點播普遍存在如下1些問題:視訊點播伺服器容量有限，1旦超出容量就無法再提供新的視訊點播服務;缺乏負載均衡的能力;容錯性差。
論文詳細講解了利用ASP、SQL Server2000、FlashMX2004、DreamweaverMX2004、Helix Server等軟體工具來開發線上視訊服務系統的過程。並簡要介紹了流煤體技術和Internet及Web技術的發展，本次設計內容主要有以下6個方面: 1.系統概述：主要是ASP的工作原理及其技術的介紹; 2.系統設計：主要是系統要實現的目標的設計，及整個系統的框架和模組的設計;3.資料庫設計與實現：主要是資料庫的連線的實現，和網頁資料庫的簡介;4.網站的整體設計：該部分主要是CSS樣式表的設計和實現;5.前端網路頁面的開發與設計：該部分主要包括了前臺檔案的總體架構和前臺主要模組的詳細介紹;6.後臺系統網路的開發與設計：該部分主要對後臺檔案的架構做了詳細說明。

The Design of VOD video service system Based-on-ASP
Abstract：The internet has grown rapidly in recent years.The bandwidth of the network, both bone network and the local access network is becoming larger and larger, which provide necessary infrastructure for broadband applications. More and more people
prefer to access information interactively. All of these create excellent condition for the development of the VOD technology Video on demand (VOD), with the Video Server (VS) storing the video programs and other multimedia information, provides the clients with interactive video service through the transmission network and Consumer Premises Equipment (CPE). Of all the parts, VS is the core of the VOD, its stability and performance decided the performance of the whole system. There are some problems in current VOD systems: The volume is limited, once the volume reaches its limitation, VOD systems cant provide service for new request; lack of load balance; poor failure recovery. This discourse was detailed to explain the exploitation of ASP, Microsoft Access2000, FlashMX, DreamwearMX Helix server...etc. software tool creation" according to Setting-up and development of systematic websites of the service of the online video . And brief introduction the development of Streaming Media technology and Internet , technical development in Webs, for following odd the content of designing: this thesis is divided into six parts primarily, one by one in order for 1.The system says all: Mainly is the introduction of the ASP work principle and technique; 2.The system design: Mainly are the design of the target that the system wants to carry out and the design of the whole frame of system and the mold piece ;3.The database design and realization: Mainly is the realization of the conjunction of the database, with the brief introduction of the web page database; 4.The overall design of the website: That part mainly is the design of the CSS style form and its carries out ;5.The development and the design of the head network page:That part mainly included the detailed introduction of the total structure and the main mold pieces of the stage document ;6.The development and the design of the backstage system network: That part mainly did to elaborate on to the structure of the backstage document.
Key words: ASP；SQL Server2000；Dreamweaver2004 MX；VOD systems。
