  8. Multicast: Experimentation in high quality distribution • DVTS 233.0.73.25 • 5.1 Streaming Audio – KEXP-FM • Harmonic – Divicom • videoLAN client 3 Mbps @ 233.0.73.29

  9. Delivering Reality: iHDTV • HD/IP >220 Mbps • www.ResearchChannel.org/dvd03 • Desktop HD delivery • MPEG2@19.2 Mbps • WM9HD@8 Mbps

  10. Big Video WorkingGroup:First steps in high quality low latency interactive experiences • SDI/IP – contribution feed quality • DV/IP • Plasma screen resolution/IP • HDSDI/IP • HDCam/IP

  11. BIG Video: DVTS - DV over the Internet • DV @ 30 Mbps • IEEE1394 (firewire) • DVTS • Software from The WIDE Project • Hardware from Fujitsu Research • DVTS Projects • International cultural events • Virtual Briefings • Video Conferencing, AG-like experiences

  12. DV - Digital Video • Digital Video, put simply, is video that has been digitally sampled • Digital Video comes in many formats and data rates: • CCIR 601/SDI@ 270-360 Mbps @ 4:2:2 • Digital composite @ 95-135mbps • MPEG2 4:2:2P @ up to 100Mbps • High Definition – SMPTE 292M, ATSC rates, and MPEG2MP@HL 13-100Mbps • Streaming Video: Real, WM, Quicktime/Darwin/Sorensen, etc.

  13. DVTS Software from the WIDE project • Runs on FreeBSD, OSX, WinXP, Linux • Requires a IEEE 1394 interface • Requires DV source • WinXP client permits desktop rendering of DV stream http://www.sfc.wide.ad.jp/DVTS

  14. DVTS Projects • Streaming applications • Virtual Briefings, Member Meeting, Cultural events • http://people.internet2.edu/%7Ebdr/CometDVIP • http://apps.internet2.edu/dvip.html • http://events.internet2.edu/briefings/dvts.html • Video Conference • Testing with UPenn, IU, Korea, UW • AG integration (AArnet, GrangeNet, Internet2) • CometDVIP “MCU”, Desktop integration

  15. iHDTV to the Desktop • Capture & Encode Architecture • Tiernan TR1 encoder • HD Capture • Apple Dual G5 • AJA Kona SD/HD capture board • Local RAID • HD Software Encoders • Heuris MPEG2 HD • Apple QuickTime HD with H.264 • Windows Media 9 HD • REALVideo 10 HD

  16. iHDTV to the Desktop • Lower Bit Rate (3-8mbps) • WindowsMedia9 • Adobe Premiere and/or MS WM9 Encoder • Multichannel Audio: 5.1, 7.1 • 1080 Interlace format issues • MPEG4 • Advanced Simple Profile – licensing issues • Real Networks • RealVideo SDK – limited experience

  18. Uncompressed HD video / IP • 1.5 Gbps transfer • Dual 2.4GHz Xeon Intel PCI-X PCs • PCI-X 10Gige NICs unavailable at build time • Data traffic split between 2 Gige NICs • AJA Xena HD output card SMPTE 292M • Clips captured from HDCam source

  19. Uncompressed HD Video / IP • Video Stored on 6 - 112GB SATA drives in RAID 3 format • Low data rate between Canberra and Cairns resulted in local network demo • Low latency predicted for “live” feeds

  20. Media delivery over IP futures • CPB Evolving the Links Project http://evolvinglinks.uwex.edu/ • IP Delivery of Content to ResearchChannel • Video delivery to PDAs • Archive Library of Congress • NASA space station video capture using DVTS

  21. Media delivery over IP futures • Migration of slow Commodity Internet to match Internet2 and NLR speeds • Next generation STB • Conversion of CATV systems to “mostly” fiber • All-ip delivery over cable • Datacasting via DTV stations
