【摘要】：本文通過對網絡視頻點播系統(tǒng)的開發(fā)背景及研究現狀的分析,提出了基于JS P的網絡視頻點播系統(tǒng)的總體業(yè)務需求,同時通過對視頻點播關鍵技術的研究,提出了視頻點播系統(tǒng)的設計與實現的有效的解決方案。本文首先對視頻點播系統(tǒng)的需求進行分析,將整個視頻點播系統(tǒng)分為系統(tǒng)管理、用戶管理、多媒體資料管理、播放控制、安全機制等幾個部分,對每一個部分都做了詳細的設計與用例分析,完成了視頻點播系統(tǒng)的功能劃分。技術上提出了視頻點播系統(tǒng)的技術架構,在功能上通過流程圖和類圖等方式對視頻點播系統(tǒng)的主要功能做了詳細設計。通過頁面圖描述了視頻點播系統(tǒng)的實現,并對系統(tǒng)實現過程中的關鍵技術做出了詳細的描述。視頻點播系統(tǒng)實現了視頻點播的主要功能,能夠對信息進行有效的管理。實現了用戶管理,視頻資料的管理,播放控制,安全機制,系統(tǒng)管理模塊功能。系統(tǒng)用戶可以對整個系統(tǒng)進行設置,普通用戶登錄后可以對自己權限內的信息進行查看與編輯,并且可以點播視頻,點播過程中可以通過視頻控制的功能對視頻播放進行控制。部門用戶可以上傳公開多媒體資料或者部門內部多媒體資料,對于上傳的視頻可以選擇是否加密,實現數據采集的功能。安全機制實現了用戶的權限控制和加密視頻播放控制功能。系統(tǒng)功能實現的頁面風格簡潔大方,給用戶提供了良好的體驗環(huán)境。為了更好的使用該系統(tǒng),系統(tǒng)為不同的用戶設置了不同的操作權限,即方便用戶的操作,又確保了信息的安全性。
[Abstract]:Based on the analysis of the development background and research status of the network video-on-demand system, this paper puts forward the overall business requirements of the network video-on-demand system based on JS P. at the same time, through the research of the key technologies of the network video-on-demand system, An effective solution to the design and implementation of video-on-demand system is put forward. In this paper, the requirements of video-on-demand system are analyzed, and the whole video-on-demand system is divided into several parts, such as system management, user management, multimedia data management, playback control, security mechanism and so on. The detailed design and use case analysis of each part are done, and the function division of VOD system is completed. Technically, the technical architecture of VOD system is put forward, and the main functions of VOD system are designed in detail through flow chart and class diagram. The implementation of video-on-demand system is described by page diagram, and the key technologies in the process of system implementation are described in detail. The video-on-demand system realizes the main functions of video-on-demand and can effectively manage the information. The functions of user management, video data management, playback control, security mechanism and system management module are realized. The user of the system can set up the whole system, the ordinary user can view and edit the information within his authority after logging in, and the video playback can be controlled through the function of video control in the process of video on demand. The department user can upload the public multimedia data or the internal multimedia data, for the uploaded video can choose whether to encrypt or not, to achieve the function of data collection. The security mechanism realizes the user authority control and encrypted video playback control function. The page style of the system function is simple and generous, which provides a good experience environment for users. In order to make better use of the system, the system sets different operation permissions for different users, that is, it is convenient for users to operate and ensures the security of information.
