SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Experiences using Uncompressed High Definition Video Erik Hofer School of Information

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Effort at the School of Information to prototype and deploy next-generation, real-time collaboration systems –Tom Finholt, Project Director –Erik Hofer, Technical Director –David Lee, MSI Student –Archer Batcheller, PhD Student –Voratima Orawannukul, MSI Student Research and development focuses on understanding the ergonomics of real-time collaboration, video conferencing technologies and high resolution visualization systems Sponsored by UM Office of the Provost and NSF (NCSA partnership) –Additional equipment provided by MGRID and Hewlett Packard The Connection Project

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN HD Video over IP for Telepresence Leveraging investments in the Michigan Lambda Rail (MiLR) to develop and deploy technologies for extremely high quality video telepresence Focus on partnership with the Research Channel / University of Washington around their iHD1500 system Helping our external partners deploy these systems –NCSA, CalIT2, UIC –CIC Course Share, Wayne State, Internet2

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Ultra-resolution collaboration environments NSF funded cyberinfrastructure projects are leading the development of high resolution visualization systems (e.g. OptIPuter) These large, high resolution tiled displays present an opportunity for next generation collaboration applications Working with partners on campus and off to explore both visualization and collaboration uses

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Production use Deployed an iHD1500 link between UM School of Information and NCSA Routinely used to support meetings between two sites –exclusively scheduled meetings so far Mix of technical and administrative uses This regular use provides some insight into the value of these links

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Does the quality matter? Much more engaging and realistic –“Nice to finally meet you in person” –Even over time, quality benefit persists When coupled with a physically large display, there is a reduced need for camera operation in some settings –Not the same need to pan-tilt-zoom as with a commodity H.323 codec Great for applications where video and audio fidelity really matter
