National Internet2 Day

Thursday, March 18, 2004

Interactive Connections,Troubleshooting, Viewing Streams, and Downloads



Interactive:
  • H.323 Videoconferencing via the Commons MCU

  •       (H.323 with H.263 video at 768Kbs)

    Troubleshooting Your H.323 Connection:

    • Configure unit to 100 Mbps, full duplex (not auto sensing)
    • Make sure your network jack is also set to 100 Mbps, full duplex
    • Make sure your unit has the latest software release on it (which should be fx release 5.1.2 or vs4000 release 5.1.2). Click here to download the most recent release.
    • If you are still experiencing difficulties with your H.323 connection after confirming the above, please call (734) 352-7055

    If you need to cascade your gatekeeper, contact H.323 technical support at 614-247-8066 or send email to commons-techsupport@internet2.edu


    Netcasting:

    The proceedings of National Internet2 Day will be netcast to accommodate different bandwidth capabilities, including:

  • Multicast*
  • Unicast Viewing Streams
  • Experimental (unproven, trial, or test technologies) Note: Technical support not provided.
    • Multicast HD 20MB 233.45.17.12/1234 Note: To use this netcast option, you must have the ability to view high-definition TV at your location. The 8:15-9:00am segment will be streamed live. This is a 720p, HD, MPEG2 stream at approximately 20MBps. At 11:00am, this content will be available via download of an 8GB file using Bittorent. At 12:00pm, the 8:15-9:00am segment will be restreamed at 233.45.17.12/1234 To view this stream, download the VideoLan Client. Recommended configuration is a Windows PC, 2.8GHz or faster, 8GB of free disk space, fast RAM and video card, and a large display or projector. The HD Camera (JVC GR-HD1) will be pointed at the speaker and a plasma monitor.
    • An HD MPEG-2 test file (http://squid.internet2.edu/announce/hdtest.ts.torrent) is available for downloading. The file is 4GB, so it may take awhile to download. You must install Bittorrent from http://bitconjurer.org/BitTorrent/download.html first. Please leave the Bittorrent window open after download. This will allows others to download portions of the file from your computer. Without this, we don't have enough bandwidth to distribute this file! Use the latest Windows version of VLC from http://www.videolan.org to play the test file back. Will require 2.8Ghz or faster CPU and fast memory and video card. Please note that there is also a multicast stream available for testing at 233.45.17.12/1234. VLC can also be used with this.
      To submit questions, use http://207.75.164.117/questiontool/QTLogin.pl .
    • Multicast DV 30mb 233.45.17.247/8000 Note: to use this netcast option you must have the ability to receive a 30 mbps multicast stream and your Windows machine must be running Windows XP and have a 1 GHZ processor. You can find the necessary Windows client at http://people.internet2.edu/~bdr/CometDVIP/dvts-xp-03-0211.exe and some instructions on how to use it at http://people.internet2.edu/~bdr/CometDVIP/dvts-1.html . To submit any question concerning email bigvideo@internet2.edu with a "Subject: need DVTS help".
  • Downloads:
  • Windows Media Player 9 (available for Windows 98 SE, ME, 2000, XP and Macintosh OS X)
  • Quicktime Player
  • IPTV Client
  • RAT Tools
  • VIC Tools
  • VBrick StreamPlayer
  • Video Lan Client (VLC)
  • DVTS


    Notes:

    *Multicast works only if your network supports multicast. Multicast detection tools include the Internet2 Detective and the Multicast Technologies tester. If you don't have multicast capability, you may want to consider a multicast tunnel, such as this one.

    †VBrick: The free StreamPlayer is incompatible with Windows Media Player 9 installed on your computer. Forward error correction is not supported; the link must be loss free.

    ‡VRVS: Polycom FX with recent firmware (4.2) cannot decode the legitimate H.261 video produced by VIC (all intraframes).
