Abstract :
This paper presents the design and development of an adaptive real-time multimedia distance learning system-EasyLearning, which supports both online learning and courseware on demand through the Internet. By combining the innovative ideas and best features of scalable video coding, screen share algorithm, session control signaling, and TCP-friendly application-based multicast protocol, EasyLearning is capable of achieving good Quality of Service (QoS) of video and audio, efficiency, and reliability of media delivery. According to the experimental comparison between EasyLearning and Microsoft media service based system (MMS), Easylearning can provide better performance than MMS.
