Dear Roger:
===========
(1) Many thanks for your msg (ATTACHMENT I).
(2) YES, I am very glad to see many of our
electronic colleagues are now
contacting each other
around the world.
This is the sure and
practical way to foster friendship, trust and peace
among them -- which
is the very basic goal of our GLOSAS.
Thanks a lot for your collaborative effort!!
(3) Thanks also for your reply comments (ATTACHMENT II).
(4) During my visit to Renaissance Center
in Dickson, TN on 3/15th, I
visited your web site
<http://www.teched.org/starlink>
with T1 line at
1.5 Mbps -- I tried
both 20 K and 220 K bps bandwidth.
I did not encounter any
buffering interruption as I reported in my
previous listserve distribution
"Exciting show on low-cost distance
learning by Roger Boston
et al. -February 20, 2000" at
<http://www.kagawa-jc.ac.jp/~steve/global-univ-2000.html>.
The
interruption occurred
when I tried with my 56 Kbps dial-up modem.
This means that we now
definitely need broadband Internet even at
everybody's desktop
in remote/rural areas!!
Dear Fadia:
===========
(5) Pls visit <http://www.corbisimages.com/pano/default.asp>
and click Jumbo
to view 360 degree panoramics.
Although this is not
streaming audio/video, you may use the same
technique for the 360
degree panoramic view of your rotunda which I
suggested in my previous
msg.
This panorama shows in almost 2/3 of my 17 inch computer screen.
I am viewing this with my PowerMac and QuickTime, but I am sure
that you can view it with your Window 98, too -- it is said that,
because of this QuickTime technology, PowerMac has an edge over
Window machine in multimedia field.
Best, Tak

Subject: Nice Job!
David word from STARLINK is that your segment
and John Hibbs were really
well received yesterday, overall I think we did
very well, and wanted to
thank you! for the nice effort.
Will write Colette and the others too shortly.
Tak you must feel good, to see some collaborative
fruits continue to
unfold from the great Tent you have pitched across
this planet over the
past few years -- see how those of us who have
gathered under that
canvass now continue with this work?
By the way I may have this up online by tonight

It is certainly the best so far I have ever seen before.

Remember:
this was a SATELLITE ONLY event.
I, as an afterthought, decided to offer this
program as a streamed media
presentation to the web as slow and fast speeds
for comparison purposes.
If we were to offer this same program as an INTERNET
event, and to small
audiences, I would have handled the visuals as
separate web pages, controlled
by the audio stream and changing at the proper
moment in the presentation,
also provided for interactivity through
(a) Keyboard live chat
(b) Multiuser audio talking room
These methods I am prepared to show at the next
workshop I do for at Manila
or this May at Manaus.

Oh yes!
And that is why I decided to show such promise,
by streaming this Starlink
event. So that more would be aware of tis
coming option.

How big is the file?
Which file do you want?
the 20K MODEM version is
16 megabytes.
the 220K high speed version is 166 megabytes
I can arrange for you to download either.

Sure.
Already figured out.
You will see in action at Manaus, or in Manila,
which ever happens first :)

Not till they saw what you have just seen did
it occur to them in such
dramatic way, that the high costs of the past
will soon be distant memories,
now that we have new and emerging options.

I will help Alex with this.
