iHDTV Open Source Project

iHDTV™ Software Suite  iHDTV Roadmap update

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

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

Technology

iHDTV™ iHD1500  iHD1500 Optiportal Integration:  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

iHDTV™ iHD1500  iHD1500 Optiportal Integration:  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

iHDTV™ iHD1500 iHD1500 Optiportal Integration:  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

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

iHDTV™ iHD1500  iHD1500 Optiportal Integration:  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

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
