A Distributed Multimedia Communication System and its Applications to E-Learning

In this paper we report on a multimedia communication system including a VCoIP (Video Conferencing over IP) software with a distributed architecture and its applications for teaching scenarios. It is a simple, ready-to-use scheme for distributed presenting, recording and streaming multimedia content. We also introduce and investigate concepts and experiments to IPv6 user and session mobility, with the special focus on real-time video group communication.Comment: Including 6 figure

Video-based eLearning in Groups: Combining SIP and Multicast in a Mobile Learning Internet Infrastructure

Rich multimedia communication in groups is the instrument of choice in various e-learning situations and is best achieved by videoconferencing, supplemented by collaborative tools. In this paper, we report on various distributed synchronous and asynchronous video-based teaching and learning scenarios using stationary and mobile technologies over IP. They are realised by a multimedia communication system including a VideoConferencing over IP (VCoIP) software with hybrid architecture derived from a SIP-initiated P2P model. The system is based on a fast, highly efficient H.264/AVC video codec implementation. We investigate new concepts for nomadic IPv6 user and session mobility, focussing on real-time group communication
