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.

free StreamPlayer is incompatible
with Windows Media Player 9 installed on
your computer. Forward error
correction is not supported;
