Let's Meet at the Mobile -- Learning Dialogs with a Video Conferencing Software for Mobile Devices
International Journal of Interactive Mobile Technologies (iJIM), 3(3):21--25

Marker: TI-I

Zusammenfassung: 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.

{Connecting the Worlds: Multipoint Videoconferencing Integrating H.323 and IPv4, SIP and IPv6} with Autonomous Sender Authentication
ISCE2009 --- 13th International Symposium on Consumer Electronics , Seite 890--893.

Zusammenfassung: In this paper we present a multipoint media conference software with extended network capabilities. Its core components combine an advanced, highly efficient H.264/AVC video coding system. Session signaling follows the SIP standard and simultaneously supports IPv4 and IPv6. Built upon an underlying peer-to-peer communication scheme, it further supports advanced integration with legacy MCUs and thereby enables hybrid sessions that extend into the H.323 world. We demonstrate how our software can span fully functional conferences across these worlds by deploying a passive gateway peer. Finally, we address security issues arising in distributed conferencing systems. It is shown, how the use of cryptographically generated identifiers enables the application to authenticate data on a packet level, thereby preventing abuse and impersonation of the conference overlay network.

``Als die Filme laufen lernten" --- Session Mobility for Videoconferencing on Mobiles

Zusammenfassung: In recent years, video conferencing solutions have started to become available as an end-to-end service on personal devices, and are now on the spot to enter the class of mobile smartphones. In this paper we report on advanced mobility services of our video conferencing software. Based on emerging standards in SIP signaling and scalable H.264 video compression, the solution supports for a seamless integration of mobile smartphones into group conferences, and in particular extends group conference management to comply with session mobility. While remaining on a conference call, a user is thus enabled to shift his presence from a stationary end system to a mobile, and continue the conversation while leaving the office.
