iHDTV … What is it?iHDTV … What is it? Low latency, uncompressed multipoint HD over IP
Project started in 1999 – 40Mbps, 270Mbps HDCAM, 1.5Gbps Format: uncompressed SMPTE 292M 4:2:2 1080i 60
Data rate total approx 1.5 Gbps per TX RX pair No compression to eliminate encode/decode latency Exploit R&E network bandwidth – No FEC
Live camera feed and file playback HD SDI input -> HD capture card -> packetize -> IP
Audio 6 channels Software mix-minus Separate packet stream – muxed with video at RX end

Research1 is an online community that allows researchers to
collaborate with peers, and share information and digital media with
the general public.
15
• Serve as a premier outlet for researchers to fulfill their public outreach requirements
• Foster interaction and communication between members of the public and researchers
• Provide a collaborative platform to teams who could potentially be geographically dispersed
Primary Functions
16
• Easily create a “Project Hub” that serves as a public-facing webspace for their work and/or a private collaboration area for team members
• Easily upload, store, tag, and publish digital media in multiple formats including video, audio, images and documents
• Publish a blog for the project to discuss ongoing work
• Interact with other researchers and the general public through project- and discipline-specific message boards, private messaging , grid toolkit, and IP-based videoconferencing
Core Features for Researchers
17
Growing population of “myspace-like” collaboratory portals
myExperiment, Sci-Vee, EcoSpace, CalIT2 Research.Intelligence, ourSpace…
“Grid, Cloud, favorite buzz word
enabled” YouTube for research
Research1 – How is it different?
Public facing, social interface to e-Research activities.
Interoperate with e-Research portals – peer collaboration.
Manage/deliver low bandwidth and high bandwidth essence objects
Multi-discipline yet research focused vs. “lost in theYouTube ether”
