  1. Update on Uncompressed HD Video over IP from GLORIAD-KR Sanggyun Kimon behalf of GLORIAD-KR HDTV GROUP

  2. Multimedia over the Internet Powerful systemBandwidth guarantee Quality BW.

  3. Networked HDTV

  4. One-way delay vs., user perception Will not need echo cancellation Will notice slight hesitation Will not notice the delay The delay is obvious to all users Recommended upper E2E delay limit 20ms 100ms 150ms 300ms 200ms LatinAmerica Etc. MiddleEast RussiaEurope Domestic(Korea) East AsiaNorth America round-trip-time/2 delay (including Encoding/decoding delay) May 2006. Based on PingER history.ping from the east Asia to the world

  5. Advantage of networked uncompressed HDTV over Broadcasting-style and its use • Advantage- Extremely low processing delay (no codec)- ultra-high presentation quality (no spatial/temporal dependency)- easy access to the application technology- interactivity (1:1, 1:N, small group N:N) • Use- Broadcasting industry HD distribution, visualization, authoring, and so forth- Digital cinema (combining with JPEG2000) reduce distribution cost, enhance presentation quality

  6. Uncompressed HDTV in the World

  7. GLORIAD-KR version of UltraGrid 1. Cost-effective system integration and development - Adopt low-cost HD-SDI Interface (AJA’s OEM_HS) - Add internal 24-bit 48KHz HW audio to the system : audio capture, separate audio RTP stream, audio playout - Support dual-port streaming with software packet-striping - SW-based multi-channel audio playout (PC sound card) 2. System Specification - Linux (Mandrake, Suse, Fedora Core 5) - EM64T dual Xeon (at least 2 PCI-X) - Dual-port 1 Gbps or 10 Gbps network interface

  8. Uncompressed HDTV Transport System: GLORIAD-KR (HDTV-OUT) Sony HVR-Z1N HD display HD-SDI converter HD-SDI signal converter Audio embedder 6-channel audio Speakers A/V transport over IP networks

  9. Uncompressed 720p HDTV : application technology in UltraGrid (USC/ISI) Ladan Gharai, “Putting the “Ultra” in UltraGrid: Full rate Uncompressed HDTV Video Conferencing”,

  11. Cost-effectiveness 50% off over USC/ISI’s UltraGrid Sender & Receiver

  12. Partners 5 Sites are using GLORIAD-KR version of UltraGrid in the Globe

  13. Grand Opening for Big GLORIAD(’05.9.5) Global Ring Network for Advanced applications Development (GLORIAD) • The first round-the-world high-performance networks jointly established by Korea, China, Unite States, Russia, Canada and Netherlands • Improve networked collaboration with e-Science and Grid applications like HEP, Astronomy, Fusion, Geosciences, Medical sciences, and so forth.

  14. Demonstrations and Experiments with GLORIAD-KR Version • iGrid 2005, Interactive 3D HD Video Transport and Collaborative Data Analysis for e-Science over UCLP.KISTI, GIST • C-K Experiments, First C-K Uncompressed HD experiment exploiting GLORIAD network.KISTI, GIST, KAIST, TsingHua Univ, CNIC • DancingQ 2006, The First Real-time Commercial Culture Event over R&E Network. ANF, KISTI, CRC, i2Cat • ELSA 2006 Pre-congress, Live Uncompressed HD broadcast of Laparoscopic Liver Surgery.KISTI, Seoul National Univ. Bundang Hospital. • SC 2006, Software-based A/V play with a low-cost uncompressed internet HDTV KISTI, GIST

  15. Demonstrations and Experiments

  16. Applications and Networking • Applications- Imagine all areas covered by commercial HDTV • Networking- Provisioned network in Layer 1 (UCLP) and Layer 2 (VLAN)- Best-effort IP network- Available network bandwidth  at least 1 Gbps 2 Gbps or 10 Gbps- Jumbo frame (9,000-byte packets) or, endpoint fragmentation in regional or local network.

  17. DancingQ 2006 • DancingQ 2006 (L2+L3), The First Real-time Commercial Culture Event over R&E Network. - Bound two lightpaths with port-based VLAN (L2)- Add L3 multicast service- Jumbo frame support- 1 Gbps E2E network bandwidth- ANF, KISTI, i2Cat, CRC, KAIST, GIST

  18. KREONet2, KISTI, Korea CAnet 4, CANARIE, Canada GEANT2, Europe CESCA, Spain RedIRIS, Spain i2CATSSpain • DancingQ 2006 (L2+L3) Toronto Nortel OME ?New York SeattleCisco ONS Calgary Nortel OME ?
