Abstract

We present a multimedia teleteaching system that integrates an electronic whiteboard with our multimedia conferencing system which supports a motion video and a shared chalkboard. The teleteaching system uses personal computers that contain a motion video CODEC, and transmits data through the ISDN basic interface (128 kbps). An electronic whiteboard is attached to the personal computer for direct input by the teacher and display of that input. With this system, a teacher can use the electronic whiteboard as a real chalkboard. He can directly write test and draw figures in the area of the shared chalkboard by using the pen provided for the electronic whiteboard with a digitizer in it. When the teacher draws something on the shared chalkboard, it is automatically transmitted to the students' site and displayed on their shared chalkboard using the functions of multimedia conferencing system. The teacher's gestures and the contents of the whiteboard are captured by a video camera and transmitted to the students' computer. Conversely, a motion video of the students is transmitted from their site to the teacher's site.<>

一种多媒体远程教学系统，使用电子白板进行动态视频和黑板的双向通信

我们提出了一种多媒体远程教学系统，该系统将电子白板与我们的多媒体会议系统相结合，支持动态视频和共享黑板。远程教学系统使用包含运动视频编解码器的个人计算机，并通过ISDN基本接口(128 kbps)传输数据。在个人电脑上附有一块电子白板，供教师直接输入并显示输入的内容。有了这个系统，老师可以把电子白板当作真正的黑板来使用。他可以使用电子白板自带的带数字化仪的笔，在共享黑板的区域内直接写测试和绘图。当教师在共享黑板上绘制内容时，该内容会通过多媒体会议系统的功能自动传输到学生的现场，并显示在学生的共享黑板上。教师的手势和白板上的内容被摄像机捕捉并传输到学生的电脑上。相反，学生的动态视频从他们的网站传到老师的网站。b>
