Dear Roger:

(1) Many thanks for your msg (ATTACHMENT I).

(2) YES!! I enjoyed your recent great show with our Tampere event alumni --
with my 56 Kbps dial-up modem and accessing to a node at Columbia
University in Manhattan, which must have been connected to a broadband
Internet trunk line. (However, the slowest, i.e., my modem speed, is
the limiting factor.)

Dear Electronic Colleagues:

I strongly suggest that you view it also at the web site listed in his msg below.

(3) I amazed with the advancement of data compression technology used by
RealPlayer. It is certainly the best so far I have ever seen before.
The audio is almost the Plain Old Telephone Service (POTS) or CD quality.

However, strangely, there were sometimes interferences with
someones' conversations -- just like when we used old analog POTS
-- e.g., during Colette's talk on Rotary Scholarship.

With this clarity, as people often say now in industrial journals,
we may be able to expect that overseas calls would become free of
charge very soon -- and hopefully, Internet, too.

(4) I experimented with three ways;

(a) with small frame,
(b) with large frame,
(c) with Lan/Cable modem (220 Kbps access -- even with my 56 Kbps modem).

(5) The small frame gave me clear audio streaming. Video was crisper
without any blurring. However, the letters on slides were very hard to read.

You are now accomplishing to have very good audio -- though there is
still huge problem (*), and the video often be ignored by students in
order to save the bandwidth for better audio quality, the next important
thing you then need to have is the CONTENTS transmission.

(*) As you said during the session with Alex Rivas, the
inconsistency of Internet (sometimes good, but sometimes bad).

You may also recall Chinese words;

When I hear, I forget.
When I see, I remember.
When I do, I know."

I then add Knowledge applied with interaction becomes wisdom."

The audio is the absolute necessity of videoconferencing, but, alas,
what the audio said often be forgotten!! You then need to supplement it
with images of CONTENTS in order to be remembered by students.

As I often said before from my experiences with analog and digital
satellite videoconferencings of Global Lecture Hall (GLH)", the
order of important items in the videoconferencing is (i) audio,
(ii) contents (text, graphics, diagrams, application/simulation
programs, etc.), and then (iii) video.

You presented those contents with slides in full frame, but the
frame itself was so small that the letters in the slides were not
readable -- forfeiting the most important mission of teaching --
transfer of contents.

(6) When I viewed it with a large frame, I noticed slight blurring as David
moved his head, but these were tolerable and much better than the one we
saw you through NetMeeting in Manaus/Amazona in October, 1998 with 56
Kbps dial-up modem.

However, the audio was often cut off, no lip-synchronization, and many
download data buffering intervals -- sometimes I had to wait for 20 to
30 minutes to start next streaming!!

On the other hand, slides were readable, of course.

(7) With clicking Lan/Cable (220 Kbps), I had to wait more often for data
download buffering.

However, when I replayed it after several of those bufferings and as
retrieving from its cache file, audio and video were very clear in a
large frame -- no audio dropping nor blurring of video.

They were better than analog/digital satellite broadcasting
videoconference, and can certainly take over them in the near
future -- even such as Space Collaboration System (SCS) of Japan
with $100 million to connect only 125 or so schools.

Prof. Sakamoto:

This is the day of future to come -- which I mentioned to
you at your office in the spring of 1999 and in Tampere.

This system is no cost, and for anyone at anywhere, compared
with your closed system.

However, this is possible only when broadband Internet with
Quality of Service (QoS)" feature is available which can
circumvent the huge inconsistency problem mentioned above -- that
is why of our Global University System with global broadband
Internet project both of which are to be financed with Global
Service Trust Fund (GSTF).

(8) Roger:

I would like to show this during my future talks. However, if I access
to this web site and receive with streaming audio/video, there will be
aforementioned trouble.

Can you send me its file? I will then be able to store it in the hard
drive of my laptop and retrieve it immediately, as if I access through
high speed line. How big is the file?

I also wonder if you can figure out to have those slides and still
images to be appeared in the right hand column with web broadcasting
while you talk.

Namely, while we watch small frame of your studio in RealPlayer,
the right frame of the web browser is showing several large crisp
studio photos -- in freeze frame mode. Then, why don't you use
this frame to show the slides as you talk? I saw you have done
this technique with PowerPoint before.

I suppose that those TV studio people are still with analog TV
commercial age and haven't thought of utilizing or combining the
magnificent features of Internet and computer power.


I want you to keep this in your mind when we do our demonstrations
at TV Amazona in Manaus and if they will broadcast it through
Internet as they did during our GLH in October, 1998.

Dear Colette:

(9) Your talk was very succinct, yet comprehensive. Congratulations to
become a master of distance learning delivery technology!! Thanks also
for your mentioning my name.

Dear Dr. Antonio Pinto-Rodrigues and other colleagues at UNIDO:

(10) When I made my talk at your office last month, you asked me the real
examples of distance learning courses, and I tried to show them at
Roger's web site -- with some difficulty of slow speed of your Internet
line (it seemed worse than my 56 Kbps).

I would strongly suggest that you try to view his show at his web site
listed in ATTACHMENT I.

Pls particularly watch/listen Colette's talk who summarized well various
low cost delivery technologies, e.g., (a) conference call, (b)
PowerPoint slides, (c) Internet chat, (d) RealAudio, and (e)
videoconferencing (NetMeeting for point-to-point and CU-SeeMe for
multipoint), etc.

You may also access his web sites listed in his address below.

(11) I suppose that your workshop in Kuala Lumpur, Malaysia in September can
access high speed Internet so that Roger can demonstrate this approach
to delegates from 6 African countries and your technology centers around the world.

(12) Prior to your workshop, you may encourage your colleagues to try
accessing Roger's web site for testing of their Internet capabilities.

Dear Richard Wah:

(13) You may use Roger's system to save one 64 Kbps INTELSAT channel, instead
of using 2 x 64 Kbps channels for ISDN type videoconferencing with
Polycom (at $20,000)!!

(14) Since each of those channels to nearby islands in the South Pacific may
not be so much congested yet, you may get almost same audio/video
quality by this approach as the Polycom's ISDN approach -- without
spending any money!!

Dear Myron, Jeff and Harvey:

(15) Pls listen Colette's talk on the conflict resolution in Kosovo.

The same technique may be applicable to your distance learning on peace
keeping in Colombia and around the world.

Dear Yoko:

(16) As you see, Internet approach is getting very close to ISDN (Integrated
Service Digital Network ==> or often said as Incredibly Super Duper
Nonsense) approach. Only we need now is to have broadband Internet --
at least, at 220 Kbps.

You better get ready to utilize various techniques as Colette described.

Dear Victor:

(17) Pls try to access Roger's web, too -- getting acquainted with those
advanced Internet technology will be the first thing for your business.

Dear Roger, Colette, David, Alex and John:

(18) Congratulations again for your very successful and exciting show!!

Best, Tak

<<February 20, 2000>> Removed the rest by T. Utsumi,

please enjoy the STARLINK Satellite event from last Tuesday featuring
Dave Johnson and Colette Mazzucelli, also Alex Rivas, John Hibbs and others,


Kim, you will prefer to watch our program streaming at 220,000 bits per
second looking very wonderful indeed, far FAR beyond the experience that
can be had by modem.

This tenth anniversary progam by Starlink is being said by some already
to be the best the have ever uplinked, Colette and Dave did a great job!
