With a passion to bring
better education to
remote areas in Thailand,
Sat-Ed System Co is
delivering learning
centres in rural Thailand
called ‘Room for life’
using the cutting-edge
technology of the iPSTAR
broadband satellite.
Aimed at providing lifelong
learning for the
rural Thai people, this
initiative is providing
access to education
content in remote rural
areas beyond the reach
of telephone networks.
Chang is a bright young man
who won a full scholarship to
a technical university in
Thailand. He had to turn it down
because, while it would pay for his
tuition and fees he had no way to
support himself living in Bangkok and
his parents were not well enough off
to pay for it either. Chang was
overjoyed when he learned about the
Sat-Ed Room for Life because it will
allow him the chance to earn his
degree without leaving the village.
There are many kids just like Chang;
kids who are bright and eager and
desperate to learn but time, money
and other circumstances keep them in
the village. With the Room for Life,
Chang and others will not have to
make the hard choice because they
can study there.
In the sleepy hamlet of Baan Nong
Pai, deep in the rural heart of Sakhon
Nakorn stands the pilot Room for
Life, a unique educational and
learning center. For the first time
anywhere in the world, a village that
has no phone lines has been able to
access broadband Internet, IPTV VoD
(providing educational video on
demand), web cam, university degrees
and a whole host of vocational
learning and e-government services.
The development of IPTV (Internet
Protocol Television) over the last 3
years has dramatically changed the
way pay TV will be seen in the future;
and yet these technologies to date
have not been used by the
educational market even though they
offer an unparalleled opportunity for
learning as well as access to digital
content.
The technology: Internet
Protocol Television (IPTV)
First one has to understand the core
technology. IPTV differs from normal
TV-based delivery systems in that
instead of being a passive device that
you watch it is now a two-way
interactive device. IPTV allows a
person to interact with the content
delivered to the TV. To the viewer, it
looks exactly like a normal TV screen
as the pages are designed for viewing
on a TV. Using a simple remote
control, a person can navigate
through a series of high-quality
videos and text pages, take tests
using the remote control to answer
the on-screen questions and be
assessed on their results.
In actual fact, these are computer web
pages are being delivered through a
thin web browser located in the IPTV
set-top box. Using middleware written
for this purpose by Sat-Ed it becomes
an interactive navigation device. This
allows the TV to be used as the
device to deliver a traditional LMS
(Learning Management System)
directly to the end-user’s TV instead
of a PC. The thin web browser then takes an HTML or Java page and
displays it on a TV screen.
Room for life- delivering
education
In the village, the Room for Life has a
great many different courses on offer.
In addition to High School and
University courses, there is a heavy
emphasis on vocational training from
agricultural practices to silk weaving
and everything in-between. This
often means that the students are
older adults who have never seen a
PC much less used one for learning.
This is where the PC is a barrier to
learning. In the same way that our
parents and grandparents would leave
the VCR clock flashing 12:00 while
waiting for a grandchild to come over
and program it, older adults not
trained on PCs look at it as an
confronting technology. Contrast
that to our experience with children in
the Room for Life. In order to be
delivered through IPTV, the video has
to be converted into an Mpeg 2
transport stream. We were running
out of time to make a deadline for
another Room for Life and, in
desperation our chief engineer trained
two of the village children, ages 11
and 14, to convert the videos to
transport streams. To our engineer’s
shock and surprise, the children
listened carefully and fearlessly
started to convert video files
flawlessly. When seasoned pay-TV
pros heard about this they were
mightily impressed. We have found
that the children under 15 in the
village are soon learning things on the
computer that took other people years
to figure out for themselves.
The adults are a different story.
Perhaps the most telling story about
the differences between the two
groups was illustrated by the time I
handed my laptop with one hand to
one of the adults to hold while I did
something else. Their eyes got wide
and they backed away, unwilling to
take on that kind of responsibility for
fear of breaking it. Their child popped
up and took it from me without
hesitation as the parent barked out
warnings to the child to be careful. I
was intrigued and tried this over and
over with different adults over the
course of several weeks and the result
was the same. All of them either
backed away or grabbed it with both
hands, visibly scared of breaking it. In
contrast the children all took it
without thinking at all.
That is where using IPTV as an
educational tool becomes so
important. It allows these adults to
access content, often in a group,
using the same technology that they
use sitting in front of their TV at
home… a remote control. With this
remote control, they can navigate
through a course; stop, fast-forward,
rewind or pause to discuss what they
have just learned. They can stop a
course for the evening and go back
and pick it up where they last left off.
Coming soon will be the ability for the
student to input their ID number into
the system and the middleware will
know where they left off so there is no
time-consuming backtracking to find
the spot. The Sat-Ed LMS will then
track their progress and report back
nightly by satellite.
Another important part of the
technology is the use of “Push”
technology. Through the use of a
next-generation of satellite such as
iPSTAR, content is “pushed forward”
so it resides on the Sat-Ed digital
library. This specially designed VOD
server caches the
educational content at
each site so when a
student accesses it
using the IPTV STB it
plays out the
transport stream
instantly, in fullscreen,
media-rich
video. This greatly
enhances the
educational
experience. The
trouble with Internetbased
e learning is
that your experience is
connection
dependent. Even with broadband
access (a rarity inside Bangkok and
unheard in the rural areas) the most
you will be able to view is a postagestamp-
sized video because the
content is created for the lowest
common denominator. You also have
to wait for the information to come
through the Internet pipeline and the
content delivery is as slow as the
slowest pipe it has to go through to
get to the user. This often creates a
scenario where, even with a
broadband connection, a person is
always waiting for the buffering to
finish; turning the World Wide Web
into the World Wide Wait.
Contrast that to VOD learning with
the content residing in the Sat-Ed
digital library on-site. It plays out an
instantaneous stream in full-screen
color. This allows extensive use of
video in training and it also gives the
students additional video cues for
enhanced learning. Studies have
shown that people learn in different
ways. By delivering as many cues as
possible to learning, you increase
dramatically the chances that one of
them will be ultimately successful for
the viewer. This mirrors the old adage
of not just telling someone what to do
but also show them what to do. With
IPTV-based learning, the video that is
delivered can address both of these at
once.
That brings us to an interesting
problem. There are a number of Computer-based
training courses
available but there is
a paucity of content
for IPTV-based
learning. Only a few
forward-thinking
organizations have
developed content so
far but as the demand
grows, the availability
will increase
dramatically. Already
curriculum is being
written that
addresses the ability to use IPTV as a
teaching tool as an adjunct to
traditional face-to-face teaching
models. Potential uses for this might
be a history class that watches a
video of news reports of the period
just studied. Another might be a
chemistry class watching a video
presentation of a chemical interaction
shown in a lab setting instead of just
reading about it. Still another might
be an anatomy class watching a video
of a dissection of a rat while following
along with their own specimen to
dissect in the classroom.
The first use of the Sat-Ed Digital
Library is the caching of educational
content for on-demand access. A
second use, almost as important in an
educational setting, is the caching of
web sites. Because education is
predicative, we can
assume that there
are a number of sites
that students will
want to access. In a
school settings
using the Sat-Ed
digital library, the
web pages are
updated nightly by
satellite and stored
on the server.
When the students
go to access it in the
classrooms all over
the country linked into Sat-Ed digital
libraries, instead of having to wait
while each person is trying to access
the same file over and over, they get it
instantly. By multicasting it once to
all the sites that are linked to the Sat-
Ed network, it saves dramatically on
bandwidth costs and greatly reduces
the burden on the in-school network.
Room for life- beyond
education
There are other uses for the Room for
Life in addition to strictly educational
uses.
Patra had not seen her children since
April last year, nearly a year ago.
Patra is not a bad mother. The
economic reality of her small village in
the Northeast of Thailand means she
has to leave to find work in the Deep
South in a rubber plantation. On
Saturday, she got to see them and talk
to them for an hour. It cost her 20
baht (50 US cents).
Patra went to an Internet café near
where she works in the South and
their grandmother brought the
children to the newly opened Sat-Ed
“Room for Life”. There her children,
Beau and Bee, were able to talk to
their mother online using a web cam
and VoIP available in the Room for
Life. The hour cost the grandmother
20 baht. Many of the villagers have
family that are away temporarily in
places all over the globe and the
ability to stayed in touch with them
through VoIP is priceless.
Also there is the opportunity to bring
the market to the village. By using
Ebay and other sites to sell their
goods, villagers can cut out the
middleman who marks up the fruits of
their labor and makes a profit simply
because the villagers do not have
access to the marketplace. With the
Sat-Ed Room for Life the global
village becomes a reality.
Each Room for Life site will be owned
by a local IT professional who invests
in the franchise. All of the profits
generated stay in the community and
there is someone who is able to
address the unique needs of each site.
Sat-Ed does its part by continually
aggregating content and responding
to requests from the field.
Currently, Thailand has an Internet
access penetration of only 11.9%.
This number is skewed on the high
side with a 29% access rate in
Bangkok. The rural areas are much
lower. By using IPTV through the
Room for Life Sat-Ed has built a
bridge across the digital divide and
helped to provide access to education
to everyone. The ability for everyone
to access knowledge is available
through this technology today. With
the technology in place in the village,
the only limits one has are the limits
to their own imagination.
