基于A(yíng)SP的VOD視頻服務(wù)器的設計
摘 要 ：近年來(lái)，Intemet有了蓬勃的發(fā)展。1方面，主干網(wǎng)和接入網(wǎng)速率不斷提高，為各種寬帶應用提供了必需的硬件基礎設施;另1方面，越來(lái)越多的人愿意交互式地觀(guān)看音視頻節目，這1切都為視頻點(diǎn)播技術(shù)的發(fā)展創(chuàng )造了良好的條件。VOD即視頻點(diǎn)播是利用視頻服務(wù)器存儲視頻節目和其它多媒體信息，通過(guò)傳輸網(wǎng)絡(luò )和客戶(hù)端設備向用戶(hù)提供交互式視頻服務(wù)的系統。其中視頻服務(wù)器是VOD系統的核心，它的穩定程度和性能，關(guān)系到整個(gè)系統的性能。當前的視頻點(diǎn)播普遍存在如下1些問(wèn)題:視頻點(diǎn)播服務(wù)器容量有限，1旦超出容量就無(wú)法再提供新的視頻點(diǎn)播服務(wù);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等軟件工具來(lái)開(kāi)發(fā)在線(xiàn)視頻服務(wù)系統的過(guò)程。并簡(jiǎn)要介紹了流煤體技術(shù)和Internet及Web技術(shù)的發(fā)展，本次設計內容主要有以下6個(gè)方面: 1.系統概述：主要是ASP的工作原理及其技術(shù)的介紹; 2.系統設計：主要是系統要實(shí)現的目標的設計，及整個(gè)系統的框架和模塊的設計;3.數據庫設計與實(shí)現：主要是數據庫的連接的實(shí)現，和網(wǎng)頁(yè)數據庫的簡(jiǎn)介;4.網(wǎng)站的整體設計：該部分主要是CSS樣式表的設計和實(shí)現;5.前端網(wǎng)絡(luò )頁(yè)面的開(kāi)發(fā)與設計：該部分主要包括了前臺文件的總體架構和前臺主要模塊的詳細介紹;6.后臺系統網(wǎng)絡(luò )的開(kāi)發(fā)與設計：該部分主要對后臺文件的架構做了詳細說(shuō)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。
