中文摘要: 基于Web的EAST（全超导托卡马克）实时视频点播系统是在原视频点播系统的基础上进行优化和改进实现的，具有实时点播EAST实验中的等离子体放电视频、搜索视频、下载视频以及逐帧分析视频等功能.该系统主要由视频合成应用程序和视频点播网站两个部分组成，视频合成程序采用socket TCP通讯的方式接收炮号信息，通过共享目录转移视频帧文件，最后利用ffmpeg将视频帧文件合成flv视频.视频点播采用B/S（浏览器/服务器）结构框架实现，通过JSP从数据库读取炮号信息实现点播功能，结合XML和JavaScript实现逐帧分析.目前本系统已经在EAST实验中投入使用，为EAST实验人员提供了极大的便利.

Abstract:EAST (Experimental Advanced Superconducting Tokamak) real-time VOD (Video on Demand) system based on Web can display the plasma discharge videos, search videos, download videos and analyze videos frame by frame, which is improved and optimized based on the old VOD system. The system mainly includes two parts:the application of video synthesis and the VOD web station. The video synthesis application accepts shot information by using socket TCP communication firstly, then moves video frames through sharing directory, finally synthetizes videos with the tool of ffmpeg. The VOD system is implemented through B/S (Browser/Server) framework. It uses JSP to realize VOD function by reading shot information from database, and analyzes videos frame by frame by combining XML and JavaScript. The system has been already used in the EAST experiment, which is of great benefit to EAST experimenter.
