DANTE contributes to iGRID 2005

DANTE's engineers have been working with CANARIE (the Canadian Research and
Education Network) and i2CAT to support an application that will demonstrate
multistream High Definition Television (HDTV) at iGRID 2005, in San Diego,
USA. DANTE’s engineers will establish lightpath connections on GÉANT, to
enable a demonstration that will see HDTV data transferred between San
Diego, Ottawa and Barcelona.

GridON is an application that converts high-resolution broadcast video into
MPEG2 format, thereby reducing the file size and resolution. The application
then uses a user-controlled light path (UCLP1) to create an on-demand,
end-to-end connection to access remote computers. The converted MPEG-2 files
can be distributed much faster and further than the source files to these
dispersed computers, for reassembly into the higher resolution format. The
“grid” of computers is far more powerful than a single machine, and allows
the data to be reassembled quickly and efficiently. Once the film has been
fully re-assembled the GridON application automatically switches off the
end-to-end connection, freeing up space on the network. The HDTV signal is
then ready for broadcast.

Many research fields already use high quality audio and visual monitoring as
an essential tool for their studies. For example, biological monitoring of
the effect of forest fires, coral reef damage and wildlife behaviour all
make use of surveillance video cameras. An application such as GridON can
make the monitoring, data transfer, analysis and archiving process much more
efficient. In the future the method may also benefit commercial
broadcasters, allowing them to quickly establish telecom links to transfer
footage relating to breaking news stories.

1 UCLP allows end users to establish end-to-end lightpaths and change the
configuration and topology of these without involving a central network
management facility.
