Abstract :
In most of the synchronous e-learning tools the video of instructor´s image is sent using only head-and-shoulder´s view. Students find this video presentation rather monotonous and instructors find it restrictive. In this paper we discuss the cinematic principles for automatically capturing a more engaging lecture presentational view. Then we describe our proposed virtual class room set-up for recording the video. Finally we discuss our scheme to stream video sequence having optimum perceptual quality by dynamically controlling frame rate and resolution, taking into considerations the type of video sequence and the required bit rate
