【摘要】：計算機技術的迅速發(fā)展帶動教育信息化的趨勢日益明顯,以多媒體為主教學方式正在逐漸替代傳統(tǒng)的教學模式,成為主流的現(xiàn)代教育形式。在教學過程中融入各種技術,包括信息化技術、多媒體技術等,這些技術的融合可以促進整個教學內容的網(wǎng)絡化以及現(xiàn)代化,這些技術與校園網(wǎng)相融合,將服務于學校教學管理,提供更加完善的教學服務,提高教學質量,這些都是各高校急需規(guī)劃和建設的方向。本課題針對浙江長征職業(yè)技術學院多媒體教室教學控制和學生訪問網(wǎng)絡資源的兩大需求,設計并實現(xiàn)一個基于校園網(wǎng)絡的多媒體控制系統(tǒng)。該系統(tǒng)按照功能需求分為多媒體教學控制子系統(tǒng)和多媒體資源管理子系統(tǒng)。多媒體教學控制子系統(tǒng)是利用多媒體教室現(xiàn)有計算機和網(wǎng)絡設備,實現(xiàn)教師機對學生機的屏幕廣播、遠程監(jiān)控、屏幕錄制和互動交流等控制;教學資源管理子系統(tǒng)是將校園網(wǎng)中的課件資源和將錄制的教學視頻資源進行集中管理,方便學生共享訪問。本論文著重研究教學控制子系統(tǒng)中的屏幕廣播和屏幕錄制功能實現(xiàn),以及資源管理子系統(tǒng)中課件的上傳下載和教學視頻管理功能的實現(xiàn)。屏幕廣播和屏幕錄制功能都在Visual C++6.0集成開發(fā)環(huán)境IDE上,結合多媒體和圖形圖像處理技術開發(fā)。資源管理子系統(tǒng)基于B/S結構模式開發(fā),課件資源庫的建設采用Java語言以“在線文檔庫”形式實現(xiàn),視頻資源的統(tǒng)一管理則是采用ASP.NET實現(xiàn)用戶在線搜索、瀏覽和點播教學視頻的。
[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.
