Be unreasonable

The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.

Don’t be too serious

The less confident you are, the more serious you have to act.

• A group of rendering nodes generate pixel data for an application

• SAGE captures the pixel data streams over tiled display

• Free Space Manager controls pixel streams

iHD1500iHD1500• Collaboration tool• High-fidelity interaction

– Accurate, precise reproduction• Picture, sound, motion

– Low latency• Temporal accuracy• Real time operation

• IP Video– Expands the definition


MotivationMotivation• STIET IGERT• MiLR• Collaboration needs• More immersive experience• Desired higher fidelity than

traditional VC– Low latency– Real time

• Explore advanced technology• Explore partnerships

IssuesIssues• Precedent

– Little or none• 10G Networking

– Production networks not feasible• 1080i HDTV uncompressed ~ 1.5 Gb / second• HP 8400 config

– HD SDI cards– Strange HP NIC Ops

• Windows XP– Configuration– Security

• Vendor/System Integrator familiarity– Typical classroom hardware may not work– HD best practices

• Standards– SMPTE, AES
