1. EUROTeV/GAN-MVL 2 nd Meeting Desy Hamburg 16.+17.06.2005 Martin Einhoff Kommunikation und Kooperation A9 Audio-/Videoconferencing

2. EUROTeV/GAN-MVL 2 nd Meeting Desy Hamburg 16.+17.06.2005 Martin Einhoff Kommunikation und Kooperation A9 Our work of the last month Searching for available communication systems more than 90 systems are on the marked some multiparty system but with limited numbers of participants many supporting Windows  few supporting Linux some supports a programming API Next step: preselection of the 6 best solutions for GANMVL and enhanced testing of their features

5. EUROTeV/GAN-MVL 2 nd Meeting Desy Hamburg 16.+17.06.2005 Martin Einhoff Kommunikation und Kooperation A9 General Communication System

6. EUROTeV/GAN-MVL 2 nd Meeting Desy Hamburg 16.+17.06.2005 Martin Einhoff Kommunikation und Kooperation A9 Which scenarios will be supported? Conversation during experiments one mono video stream per partner mono and spatial audio support use of standard hardware Remote machine maintenance one stereo video stream stereo video visualization immersive audio special hardware needed natural recordings with dummy-head stereo display

7. EUROTeV/GAN-MVL 2 nd Meeting Desy Hamburg 16.+17.06.2005 Martin Einhoff Kommunikation und Kooperation A9 Requirements ? Conferences with more than 2 participants Enhanced networking support WAN, LAN, public Internet Firewall compatibility TCP, UDP Support of several hardware Laptop with Wireless-Lan access at journeys Desktop PC with DSL at home High end Computer at work

8. EUROTeV/GAN-MVL 2 nd Meeting Desy Hamburg 16.+17.06.2005 Martin Einhoff Kommunikation und Kooperation A9 Requirements ? Witch kind of data should be distributed by the A/V-communication subsystem ? Only communication audio/video ? Or also other video data like machinery video ? videos from instruments (oscilloscopes …) ? Transmission a captured desktop needs more computing power and bandwidth than the transferring of pure application data !

9. EUROTeV/GAN-MVL 2 nd Meeting Desy Hamburg 16.+17.06.2005 Martin Einhoff Kommunikation und Kooperation A9 Application Sharing Some remarks: sharing a whole desktop  selective sharing of individual application windows ? same access rights to all applications visible on the desktop  individual differentiation between view and work access ?

10. EUROTeV/GAN-MVL 2 nd Meeting Desy Hamburg 16.+17.06.2005 Martin Einhoff Kommunikation und Kooperation A9 Questions? Thank you for your kind attention!
