Distance Learning of P2P-based Live Media Streaming

Abstract

Distance learning is a brand-new pedagogy which the government is energetically popularizing right now. Different from the traditional teaching modes which need students gathering in class, distance learning is a pedagogy using multimedia and network service to eliminate the limitations of time and space. Furthermore, distance learning uses the network digital system to send messages point-to-point or point-to-multipoint. Presently, distance learning has gained remarkable results in universities and colleges. However, traditional teaching modes are still often used in junior and elementary schools. This paper experiments the operation of P2P Live Media Stream, a distance video system based on P2P structure. In addition, we also compare it with Co-Life Video Conferencing System developed by the National Center for High-Performance Computing and Marratech Online Video Conferencing System developed by a subsidiary company of Google. The comparisons focus on the smoothness of video signals, stability, connection recovery and transmission situations. We prove that P2P Live Media Stream is an ideal and feasible system which can be used in campuses. Furthermore, it combines all kinds of video teaching modes and benefits the teaching diversity in campuses.
