| Digital
camera with interchangeable lens |
We
will use a Canon XL-1 digital video camera, with interchangeable lenses
to film the video images of this eclipse. Using a telescopic lens not
usually available for video cameras, we will be able to film full screen,
detailed images of this eclipse.

| Japan
Gigabit Network |
From
each observation location throughout Japan, digital video (DV format) will
be sent in uncompressed format to the Network Operation Centre (NOC) in
Tokyo. In order to be able to send the data in uncompressed form a bandwidth
of 45M/bits per second is necessary. This is obtained by using the Japan
Gigabit Network. JGN is a very high speed network provided by telecommunications
and broadcasting organisations for research and development. For further
information please refer to; http://www.jgn.tao.go.jp Using this network
it is even possible for us to broadcast clean, combined images.

| Communications
Satellite |
| From
the Kanto area we will transmit images from a satelitte live broadcast vehicle
to the Super Bird communications satellite. In this way it is possible to
send high speed transmissions even from locations with no high speed land
lines. Our prime location candidate is the base of Mt. Fuji, but the location
may be changed depending on weather conditions. |
| RADIX,
Tenbin |
In
order to send video images from our local server to viewers, we will use
RADIX and Tenbin software. RADIX is open software which controls network
routing information. http://www.toyama.net/~ikuo/radix
Tenbin is technology developed by Kyushu University which uses various information
to inform users of the server location.http://www.tenbin.org
During this eclipse, RADIX will use routing information to obtain information
about suitable servers and using that information Tenbin will route users
to the closest, suitable server.

| Web
Server |
So
that many users can access the site during the eclipse without congestion,
Yahoo and Lycos Japan will host the broadcast for us.
