Jim DeRoest Director, e-Science Initiatives Pacific Northwest Gigapop Director, Technology Initiatives ResearchChannel, U Washington deroest@washington.edu High Definition Video & Collaboration Platforms for e-Research
Agenda • iHDTV – High Definition Video Conferencing • Platform Architecture • Development History • Research1 – Social Web Platform for e-Science • Features • Demonstration • Roadmap Title of Presentation, if desired
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 N-Way Conferencing • iGrid, SC’05, SC’06
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 Mike Wellings wellings@washington.edu Jim DeRoest deroest@washington.edu
Research1 is an online community that allows researchers to collaborate with peers, and share information and digital media with the general public. Title of Presentation, if desired
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
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
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
Architecture • .Net , Web 2.0 platform • Social Services – Community Server • Federation Services - Shibboleth, InCommon • Asset Management - DigitalWell
Next Steps … Phase II Simplify access/sharing – conduit to where science happens • Portals and applications Teragrid, Birn, Many Eyes, Hastac, Mirex, Dariah, … • Platform suites OSG VDT, OGF SOKU, GENI, Semantic Web, … • Communities, Virtual Organizations I2 CoManage, GSI, GridShib, VO, …
Next Steps … Phase II Services • Computational Grids Live visualization, rendering, encoding services, portals • Data Grids Structured/unstructured data, semantic tagging • Video Conferencing iHDTV1500 N-Way , UltraGrid, … • PDA services Email blog posting, iPhone video player, …
Deployment Timeline • Current: Beta prototype selected early adopter PI’s • Summer ‘08: Phase 2 research collaboration services • Collaboration Invitation • Interest in creating a Research1 project spaces • Architecture development, research, partnership • Contact, Information Jim DeRoest deroest@washington.edu Amy Philipson amy@washington.edu
