It can’t deal with the urgent state and wastes human resources. In this thesis, we propose a protocol and implement a server to control the remote devices. It can overcome the inconvenience of audio-visual file transfer, and the urgent state can be dealt with. The audio-visual materials are transmitted to the advertising device through the network, and the policies which the control center defined are conveyed to each machine through the network too, do not need to change the files artificially. The server we proposed offers the administrator to define the policies to make the advertising device broadcasting on schedule, and manage the relevant audio-visual materials with the function that modify immediately. Let the remote devices to download the policies and relevant audio-visual files, and broadcast relevant audio-visual files according to the administrator’s demand, avoid operating manually. We have to define the policies and the communication protocol between server and devices. The devices only need to update the relevant materials regularly through the network to achieve the goals of remote control and dealing with the emergency, for example halting broadcasting, or inserting text to marquee.致謝 i 中文摘要 ii Abstract iii 內容目錄 iv 圖表目錄 vi Chapter 1 序論 1 1.1 數位內容時代 1 1.2 網路伺服器 2 1.3 模組定義 3 1.3.1 中介伺服器 3 1.3.2 網路串流伺服器 4 1.3.3 Multicast伺服器 4 1.3.4 Download伺服器 5 1.3.5 HTTP伺服器 5 Chapter 2 相關技術 6 2.1網路串流伺服器 6 2.2隨選視訊伺服器 9 2.3多點傳播伺服器 10 Chapter 3 系統架構 11 3.1系統架構概述 11 3.1.1系統運作架構 12 3.1.2運作流程 12 3.1.3播放機所支援的功能列表 13 3.1.4下載內容 14 3.2伺服器端 15 3.2.1 Site Manager 15 3.2.2 Agent Manager 15 3.2.3 Dispatch Module 16 3.2.4 Tables 21 3.3 客戶端 24 3.3.1 Policy Parser Module 24 3.3.2 Playlist Player Module 26 3.3.3 Request Module 26 Chapter 4 系統實作成果 28 4.1政策排程 28 4.1.1 政策格式 29 4.1.2 政策傳遞 30 4.2節目管理介面 31 4.3群組管理介面 34 Chapter 5 結論及未來工作 36 5.1結論 36 5.2未來工作 36 參考文獻 381073598 bytesapplication/pdfen-US節目群組政策播放機伺服器programgrouppolicydeviceserver多媒體廣告下載伺服器之設計與實作Design and Implementation of Download Server for Multimedia Advertisementthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/53709/1/ntu-95-R93922116-1.pdf
