  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

  4. 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

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

  6. VenueService

  7. 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

  8. The Good (cont.) • 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

  9. 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

  10. 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
