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
iHDTV … Hardware
 Hardware OS configuration
Commodity Dual Proc or Core Duo PCI Express
HD capture cards –
TX Blackmagic Declink, RX AJA Xena
Windows XP - investigating Linux
capture card driver issue
 Latency
Approx 120ms + network delay
TX (2 frames), RX (2 frames)
Hardware frame buffering “feature” of capture cards
iHDTV … Display
 Tiled screen - participants
Sub-sampled 1.5Gbps/number of TX clients
TX tiles multicast by venue service
Tiled screen and layout constructed by RX client
 Full screen – primary speaker
Controled by venue sevice
Instructs sender to include TX remainder
Multicast by venue service
 Total bandwidth full screen display + tiled display = 3Gbps
iHDTV … Network
 Need jumbo enabled bandwidth!!!
 Total bandwidth full screen display + tiled display = 3Gbps
 Packet replicators for multicast/unicast tunneling
iHDTV N-Way Venue
Configuration
Remote client site equipment:
2 RX iHDTV systems
1 TX iHDTV systems
Persistent UW venue site equipment:
8 RX iHDTV systems
2 TX iHDTV systems
Packet Replicators for multicast/unicast tunneling
iHDTV Remote Client
iHDTV Venue Service
iHDTV N-Way Conferencing
 iGrid, SC’05, SC’06
iHDTV Extreme: iGrid VISIONS’05
iHDTV and Optiportal – SC’07
 Integration with EVL Sage
Runs as a Sage application using Sage libraries
Software rendering on the RX end
Audio managed by iHDTV
Software rendering latency
similar to hardware
iHDTV … Status … Work to Do …
 Status
Persistent N-Way service - U Wash, CalIt2, U Mich, U Wisc
Optiportal integration
Open source – source forge, Apache 2 - http://www.ihdtv.org
 Research Projects
GUI – Operation, monitoring, stats,etc
RX rendering on the desktop
NTT i-Visto integration – ½ frame latency
4K – Red camera, Quad iHDTV transport
Codec/bandwidth bridging service
Interoperation – UltraGrid, et al
 More Information

Research1 is an online community that allows researchers to
collaborate with peers, and share information and digital media with
the general public.

Primary Functions
• 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
15
Core Features for Researchers
• 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
16
Growing population of “myspace-like” collaboratory portals
myExperiment, Sci-Vee, EcoSpace, CalIT2 Research.Intelligence, ourSpace…
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”
“Grid, Cloud, favorite buzz word
enabled” YouTube for research
