Abstract

Mobile learning demands real-time transmission of lecture videos to mobile users over wireless networks. However, wireless video streaming is challenging due to the dynamic change of network bandwidths and the variety of mobile devices. In this paper, we present a mobile learning system that incorporates semantic-level scalable video coding and wireless video streaming. The lecture videos are encoded into different quality levels with different compression ratios. We demonstrate the effectiveness of our mobile learning system with the lecture videos recorded in real classrooms.
