纯软件版的多媒体网络教学系统开发

Development of a Software-Based Multimedia Network Teaching System

与基于硬件的多媒体网络教学系统相比,纯软件系统以其成本低廉,安装简单,容易升级,不受教室的物理空间限制等优点将成为未来的应用方向。提出了该系统的设计目标和设计思想,设计rCOMPUTER控件等几个功能模块,说明了屏幕图象的处理方法。基本完成了视听教学、黑屏处理、屏幕监视、学生举手等功能。今后还需要完善语音传输的实时性和信息管理功能。

Compared with hardware-based multimedia network teaching system, software-based system will be the best application in the future with its low cost,simple installation and maintenance, easy updating and never restricted by the space of school room. Here,the developing target and principle of the system are mentioned firstly. Some of functional modules such as COMPUTER control are developed. The processing method of screen image is also stated in detail. At last, the basic functions such as mutual session,screen-blacked processing and monitoring of screen for students are finished. The features of real-time voice transmission and information management will be perfected in the future.
