Abstract
Mobile phones and related gadgets in networks are omnipresent at our students, advertising itself as the platform for mobile, pervasive learning. Currently, these devices rapidly open and enhance, being soon able to serve as a major platform for rich, open multimedia applications and communication. In this report we introduce a video conferencing software, which seamlessly integrates mobile with stationary users into fully distributed multi-party conversations. Following the paradigm of flexible, user-initiated group communication, we present an integrated solution, which scales well for medium-size conferences and accounts for the heterogeneous nature of mobile and stationary participants. This approach allows for a spontaneous, location independent establishment of video dialogs, which is of particular importance in interactive learning scenarios. The work is based on a highly optimized realization of a H.264 codec.
Highlights
Remote and distance learning aims at facilitating a process of immersive qualification and life-long personal development, and does not primarily focus on a supplementary aid for memorizing facts
In the second part of this paper we present the underlying peer-to-peer group communication scheme, which performs well for medium-size conferences and accounts for the heterogeneous nature of mobile and stationary participants, cf. section 2 and 3
We have presented a hybrid peer-to-peer software for high-quality videoconferencing on mobiles, admitting utmost flexibility with respect to end systems, operators and network provisioning
Summary
Remote and distance learning aims at facilitating a process of immersive qualification and life-long personal development, and does not primarily focus on a supplementary aid for memorizing facts. In the second part of this paper we present the underlying peer-to-peer group communication scheme, which performs well for medium-size conferences and accounts for the heterogeneous nature of mobile and stationary participants, cf section 2 and 3. This includes on the one hand SIP [2] standard compliant session signaling with respect to group communication, and on the other hand efficient, serverless media distribution, selfadjusting to the actual network infrastructure support. Conclusions and an outlook on future work follow in the final section
