Real-Time HDTV Broadcast
from USA to Japan Enabled by Advanced Networks
Japan's JGN2 Symposium 2005 Features Keynote Speaker
Larry Smarr of UCSD Broadcast Live from Seattle over Advanced Optical
Networks
January 18, 2005 - Dignitaries and researchers
attending the JGN2 Symposium 2005 in Osaka, Japan today listened
and watched as Internet visionary Larry Smarr gave the keynote presentation
on a large HDTV screen above the podium. Unlike traditional keynote
talks, however, Smarr was 5,000 miles away in Seattle, Washington.
And unlike traditional in-person talks the quality, size and resolution
was so great that audience noted they could see every hair on the
speakers head.
Advances in transmitting live, uncompressed high-definition television
(HDTV) signals over optical networks are enabling true tele-presence,
in which participants feel they are together in the same room. The
Internet HDTV broadcast system used for this event was developed
by the University of Washington for ResearchChannel. A server in
Seattle transmitted uncompressed, real-time, high-definition digital
video and digital audio at very high quality and very low latency
to a client system in Osaka. Professor Smarr's presentation originated
on the University of Washington campus in Seattle and was transmitted
without using any compression at 1.5 Gbps to the Pacific Northwest
GigaPoP (PNWGP), then across a 10 Gigabits per second (Gbps) transpacific
link from Seattle to Tokyo, and then via the JGN2 to Osaka. The
transpacific link was provided by the Internet Educational Equal
Access Foundation (IEEAF), and which is managed by the PNWGP in
Seattle and the WIDE project in Japan.

Smarr, director of the California Institute for Telecommunications
and Information Technology [Cal-(IT)²] and principal investigator
of the National Science Foundation-funded OptIPuter project, talked
about the emergence of a new cyberinfrastructure based on network
parallelismdedicated optical paths, in which distributed clusters
and instruments are tightly coupled using multiple wavelengths of
light, or lambdas, on single optical fibers. The ability to stream
video at several gigabits per second of data in parallel, like in
this HDTV transmission, is enabling new modes of communication and
collaboration. The clear crisp images and sounds that HDTV affords
make for better dialogue and interaction with colleagues over distances,
said Smarr, who is also a professor at the University of California,
San Diego (UCSD) Jacobs School of Engineering. The goal is to make
these sorts of communication technologies persistent, so that far-away
colleagues appear to be just beyond the Looking Glass.
In his talk, Smarr noted that Cal-(IT)² is incorporating
advanced video-over-fiber networking technologies into its two new
buildings at UCSD and UC Irvine. Facilities are slated to include
a digital cinema and HDTV production facility, as well as dedicated
meeting and public spaces with large-format displays to support
telepresence and collaboration. Said Smarr: "Every type of
research will benefit if we can tear down walls and let scientists
and engineers talk and work together in real time as if they were
in the same room -- even if they’re thousands of miles away."
Tomonori Aoyama, a professor of Information and Communication
Engineering at the University of Tokyo, chair of the JGN2 management
committee, and chair of the Symposium's keynote session, expressed
his sincere gratitude to all who contributed to its success. "The
goal of the Symposium was to present the research and development
activities taking place using Japan's JGN2, operated by the National
Institute of Information and Communications Technology (NiCT),"
said Aoyama. "I am very pleased that we used JGN2 and IEEAF
broadband network technologies during the featured remote presentation
by Dr. Smarr to explain the needs and applications for these technologies."
JGN2, an advanced network testbed for research and development,
is both a national and international testbed. It supports high-speed
networking technologies and application advancements. Nationally,
JGN2 is a 20 Gbps backbone network that has access points in all
Japanese prefectures. Internationally, JGN2 connects Tokyo via a
10 Gbps link to the StarLight facility in Chicago, where it peers
with the USA’s National LambdaRail, Abilene and other advanced
international, national, and regional research and education networks.
"This is a milestone both in the use of technology and the
establishment of a new high-water mark in extraordinarily close
international collaborations.," explained Ron Johnson, Vice
President of Computing & Communications at University of Washington,
"We are collectively managing dedicated lightpaths to carry
uncompressed HDTV while at the same time supporting scientific research
such as the Huygens Titan probe with a lambda-based network infrastructure
that links Asia, Australia, Europe, and North America. We are working
with colleagues at JGN2, WIDE, IEEAF, PNWGP, StarLight, University
of Washington, ResearchChannel and other like-minded entities worldwide
are working together to create "deterministic" networks
using multiple lambdas over optical fibers, to guarantee the bandwidth
speeds and latency in order to do things like real-time HDTV transmission
and remote steering of scientific instruments. We will continue
to pursue this, to make applications like high-quality HDTV transmission
both persistent and ubiquitous."

About JGN2
JGN2 is a new Japanese ultra-high-speed open testbed network for
R&D collaboration between industry, academia, and government,
operated by the National Institute of Information and Communications
Technology (NiCT) of Japan. JGN2 was established in April 2004 with
the aim of promoting a broad spectrum of research and development
projects, ranging from fundamental core research and development
to advanced experimental testing, in areas including the advancement
of next generation technologies for networking and diverse network-based
applications. JGN2 provides nationwide Japanese IP networks, optical
wavelength networks, and R&D environments for optical testbeds.
JGN2 was extended internationally in August 2004 with the addition
of a 10 Gbps transpacific link between Japan (Tokyo) and the USA
(Chicago). (http://www.jgn.nict.go.jp/e/)
