1. ConferenceXP A versatile video conferencing tool for the Performing Arts José Feghali Texas Christian University School of Music

2. ConferenceXP – a brief history Project began at Microsoft Research in 2001 Successful deployment for distance learning, Spring 2003 First 4-way distance learning deployment Autumn 2004 Center for Collaborative Technologies at UW established, July 2007 August 2008, CXP 5.0 released

3. TCU/RAM Masterclass 2007

5. 2008 Developments CXP 4 - audio limited to 22 Kbps Uncompressed audio – possible? It is all about buffers! Sync Bonus = (compressed) video with uncompressed audio, any audio source Up to 16 bits, 48 KHz stereo (and above?) Quality V/C ~ 3 Mbps (1.5 Mbps video) Uncompressed video and audio ~ DVTS

6. Proof of concept >>> CXP 5 Advanced Settings >>>

7. Venue Service

8. The Good Free for educational and research use Video/Audio independence with sync adjust Webcam, DV video or other video input Internal and external audio Low latency Multicast, unicast, reflector service Multipoint conferencing (bandwidth?) with multiple compression levels Multi-camera possibilities from one location

9. Security (venue password, encryption) Nat/Firewall transversal, diagnostics Ability to stream CXP session live (WM) Archive service = recording + playback “Bonus” features include chat, presentation, whiteboard, screen sharing, video playback Intel Mac (iSight drivers from boot camp) Wiki, forums, listserver The Good (cont.)

10. The Bad No DV audio (yet…) ** STOP PRESS** Compressed DV video requires WMP10 VISTA use requires installing CODEC - may not work with compressed DV video Accurate testing = use two computers High compression = high CPU usage

11. Usage Notes and Future Some firewire devices work, others don’t Metronome method for synching.NET framework – archive requires SQL Firewall ports DV video – lower than 720x480 resolution High bandwidth = switch off FEC Future plans: HD, multi-channel audio (?), venue redesign – CXP 5.1 in March 2009
