Presentation Transcript

  1. 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

  2. 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

  3. 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

  4. 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

  5. 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

  6. iHDTV … Network • Need jumbo enabled bandwidth!!! • Total bandwidth full screen display + tiled display = 3Gbps • Packet replicators for multicast/unicast tunneling

  7. 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

  8. iHDTV Remote Client

  9. iHDTV Venue Service

  10. iHDTV N-Way Conferencing • iGrid, SC’05, SC’06

  11. iHDTV Extreme: iGrid VISIONS’05

  12. 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

  13. 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

  14. 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

  15. 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

  16. 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

  17. 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

  18. Demonstration

  19. Architecture • .Net , Web 2.0 platform • Social Services – Community Server • Federation Services - Shibboleth, InCommon • Asset Management - DigitalWell

  20. 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, …

  21. 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, …

  22. 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
