  1. 1. High Definition Video Real Time Multipoint Distribution Lud e k Matyska CESNET & Masaryk University Brno Czech Republic
  2. 2. What <ul><li>Use HD (1920x1080, 60 fields (half frames) per second) to capture, store and distribute high quality video material for scientific and educational purposes – streaming </li></ul><ul><li>Use of HD to support high quality videoconferences </li></ul><ul><li>Research at multipoint high bandwidth stream distribution using overlay user controllable networks </li></ul>
  3. 3. iGrid2005 Demo Setup <ul><li>HD Multipoint Videoconference (CZ101) </li></ul><ul><li>Three participating sites: </li></ul><ul><ul><li>Masaryk University Brno, Czech Republic </li></ul></ul><ul><ul><li>Louisiana State University, Baton Rouge, Louisiana </li></ul></ul><ul><ul><li>UCSD, San Diego </li></ul></ul>
  4. 4. How (Video) <ul><li>Capture </li></ul><ul><ul><li>HD camera SONY HVR-Z1E or HDR-FX1 </li></ul></ul><ul><ul><li>AJA HD10A for analog (YUV) to SDI and DVS Centaurus for hw capture of HD-SDI </li></ul></ul><ul><ul><li>Encapsulation into IP using custom UltraGrid-based software, Chelsio 10Gb NICs (jumbo frames) </li></ul></ul><ul><ul><li>No compression, data stream of 1.5Gbps </li></ul></ul><ul><li>Projection: </li></ul><ul><ul><li>Decapsulation (including 10b to 8b color reduction, AMD64 optimized deinterlace implementation) </li></ul></ul>
  5. 5. Video Configuration and Network
  6. 6. How (Network) <ul><li>Virtual overlay network </li></ul><ul><ul><li>Stream replication point(s) with software or hardware replication unit </li></ul></ul><ul><li>User controllable packet reflector </li></ul><ul><ul><li>10 GE NIC from Chelsio </li></ul></ul><ul><ul><li>Dual AMD64 machine with 4GB RAM (BSD clone) </li></ul></ul><ul><ul><li>Only duplication of the 1.5 Gbps stream </li></ul></ul><ul><li>Optical splitter considered </li></ul><ul><ul><li>Access to the L1 needed </li></ul></ul>
  7. 7. Reflector Setup
  8. 8. Why <ul><li>HD provides good compromise between sufficient details in the picture and the price of necessary equipment (cameras and projection/display systems) </li></ul><ul><ul><li>Videoconferencing </li></ul></ul><ul><ul><li>Interest by physicians for educational purposes </li></ul></ul><ul><ul><ul><li>Surgery capture </li></ul></ul></ul><ul><ul><li>Streaming access to lectures and other edu material </li></ul></ul><ul><li>High bandwidth to create challenge for network development </li></ul>
  9. 9. Problems <ul><li>Instability of dual AMD Opteron machines with 10GE Chelsio cards (T110/T210) </li></ul><ul><li>No full control over the newtork </li></ul><ul><ul><li>Unexpected glitches out of our control </li></ul></ul><ul><li>Still too high latency – still >500ms </li></ul><ul><ul><li>Network gave 178ms between Brno and San Diego compared to the theoretical 50ms </li></ul></ul><ul><ul><li>Even uncompress video processing adds at least 100ms (both sides) </li></ul></ul><ul><ul><li>Replication units </li></ul></ul>
  10. 10. Partners and People <ul><li>CESNET/Masaryk University Brno: </li></ul><ul><ul><li>Lud ěk Matyska , Petr Holub , Milo š Liška , Lukáš Hejtmánek, Jiří Denemark, Tomáš Rebok, Eva Hladká </li></ul></ul><ul><li>CESNET: </li></ul><ul><ul><li>Jan Radil , Stanislav Šíma, J an Gruntorád </li></ul></ul><ul><li>Louisiana State University : </li></ul><ul><ul><li>Andrei Hutanu , Ravi Paruchuri, Brian Ropers-Huilman , Ed Seidel </li></ul></ul>
