Abstract

Online live class services have become more and more popular among various kinds of educational activities. In the PPClass system designed by my working group, students can not only watch live video of the teacher, but also the captured frames of the PPTs displayed on his or her screen. But when it comes to playing a video on teacher side, screen encoding can’t guarantee the smoothness of the video. This paper mainly discusses how to design and develop a subsystem based on FLASH for such VOD services, which can keep synchronization between teachers and students compensating for the problem above.
