  20. iHDTV Open Source Project

  21. iHDTV™ Software Suite • iHDTV Roadmap update

  22. iHDTV™ iHD1500 • iHD1500 • Uncompressed SMPTE 292M 4:2:2 • Data rate total approx 1.5 gbps • Requires: • Uncompressed HD capture cards • PCI Express platforms • Windows XP • 2 x gige or 1x10gige network connection • Jumbo frame transport and routing

  23. iHDTV™ iHD1500 • 3 PCI-Express 3.4GHz Dual Xeon platforms (minimum spec) • 2 AJA Xena-HS capture boards for RX • 1 Decklink HD Plus capture board for TX • New board alternatives being evaluated • Viewcast Osprey 700 HD • NTT Labs i-VISTO

  24. Technology

  25. iHDTV™ iHD1500 • iHD1500 OptiportalIntegration: • Goal to place live HD video in OptIPortal Window from iHDTV application • Non-typical OptIPortal hardware required • Some modification of iHD and SAGE required • SAGE = Scalable Adaptive Graphics Environment • Successfully demonstrated at SC07

  26. iHDTV™ iHD1500 • iHD1500 OptiportalIntegration: • iHDTV+SAGE option • Cause iHDTV to output to the composite display using SAGE as an “off-the-shelf” library to handle image splitting • Overlay Option • Run an instance of iHDTV on each SAGE display node Send a pre-split picture to each node along with display information

  27. iHDTV™ iHD1500 iHD1500 OptiportalIntegration: • iHDTV+SAGE option contstraints • Images had to be kept small to aviod distributing the load across the entire display system • Support for 2gige NICs had to be built into SAGE • 10gige or Infiniband not possible at the moment • Enable jumbo frames on all SAGE interfaces • Modify iHDTV to use the SAGE library

  28. iHDTV™ iHD1500 • iHD1500 OptiportalIntegration: • Hardware requirements • Intel Core 2 Duo E6750 Conroe 2.66GHz • EVGA 122-CK-NF63-TR motherboard • 2 GB of PC3 10600 1333MHz memory • Intel PRO 1000PT Dual Port PCI Express NIC • PNY GeForce 8600GT 256MB PCI Express x16 video card • Specs similar to iHDTV node

  29. iHDTV™ iHD1500 • iHD1500 OptiportalIntegration: • Overlay Option resulted in a nice render-to-screen function for iHDTV which will be incorporated in the code base • Support for multiple network interfaces required running two instances of SAGE for each logical half of each display

  30. iHDTV™ iHD1500 • Suggested changes to SAGE: • Modify the SAGE display manager to accept a parameter specifying an IP address for binding sockets • Modify the SAGE display manager to accept a parameter specifying the position of its window relative to the overall display • Modify the code for the SAGE window manager to accept per-node configuration for the above parameters • Modify the SAGE code for determining the size of the part of the image blanked out due to the physical frames of each display. • Use XVideo rather than OpenGL which would allow our application to run 4 times faster in the Overlay Option
