【摘要】：计算机技术的迅速发展带动教育信息化的趋势日益明显,以多媒体为主教学方式正在逐渐替代传统的教学模式,成为主流的现代教育形式。在教学过程中融入各种技术,包括信息化技术、多媒体技术等,这些技术的融合可以促进整个教学内容的网络化以及现代化,这些技术与校园网相融合,将服务于学校教学管理,提供更加完善的教学服务,提高教学质量,这些都是各高校急需规划和建设的方向。本课题针对浙江长征职业技术学院多媒体教室教学控制和学生访问网络资源的两大需求,设计并实现一个基于校园网络的多媒体控制系统。该系统按照功能需求分为多媒体教学控制子系统和多媒体资源管理子系统。多媒体教学控制子系统是利用多媒体教室现有计算机和网络设备,实现教师机对学生机的屏幕广播、远程监控、屏幕录制和互动交流等控制;教学资源管理子系统是将校园网中的课件资源和将录制的教学视频资源进行集中管理,方便学生共享访问。本论文着重研究教学控制子系统中的屏幕广播和屏幕录制功能实现,以及资源管理子系统中课件的上传下载和教学视频管理功能的实现。屏幕广播和屏幕录制功能都在Visual C++6.0集成开发环境IDE上,结合多媒体和图形图像处理技术开发。资源管理子系统基于B/S结构模式开发,课件资源库的建设采用Java语言以“在线文档库”形式实现,视频资源的统一管理则是采用ASP.NET实现用户在线搜索、浏览和点播教学视频的。
[Abstract]:With the rapid development of computer technology, the trend of education informatization is becoming more and more obvious. The multimedia teaching mode is gradually replacing the traditional teaching mode and becoming the mainstream modern education form. Including information technology, multimedia technology and so on, the integration of these technologies can promote the networking and modernization of the whole teaching content. The integration of these technologies with the campus network will serve the school teaching management and provide more perfect teaching services. To improve the quality of teaching, these are the directions that colleges and universities urgently need to plan and build. This topic aims at the two major demands of multimedia classroom teaching control and students' access to network resources in Zhejiang Changzheng Vocational and Technical College. A multimedia control system based on campus network is designed and implemented. The system is divided into multimedia teaching control subsystem and multimedia resource management subsystem according to the functional requirements. The existing computer and network equipment in the classroom, The management subsystem of teaching resources is to manage the courseware resources in the campus network and the recorded teaching video resources in a centralized way, and to control the screen broadcasting, remote monitoring, screen recording and interactive communication of the students' computers by the teachers' computers, the management subsystem of teaching resources is to manage the courseware resources in the campus network and the recorded teaching video resources. This paper focuses on the realization of screen broadcast and screen recording in the teaching control subsystem. The functions of courseware upload and download in resource management subsystem and the function of teaching video management are realized. The functions of screen broadcast and screen recording are both on Visual C 6.0 integrated development environment IDE. The resource management subsystem is developed based on the B / S structure mode, and the courseware resource library is constructed in the form of "online document library" in Java language. The unified management of video resources uses ASP.NET to realize online search, browse and on-demand teaching video.
