Transcontinental Duet Uses Gigabit Connection, LOLA Technology
CHATTANOOGA, Tenn. --(Business Wire)--
Details are released about Saturday's transcontinental duet performed
for a live audience of 4,000 in Chattanooga, Tennessee.
Grammy winning producer and musician T-Bone Burnett performed "The Wild
Side of Life" with BR549 founder Chuck Mead. The Chattanooga audience
witnessed live collaboration between Burnett from a Los Angeles studio,
and Mead on stage in Chattanooga, using gigabit-per-second Internet
connectivity and new video conferencing technology.
The video conferencing technology, LOLA (LOw LAtency audio
visual streaming system), was developed jointly by the Tartini Music
Conservatory in Trieste, Italy and Consortium GARR in conjunction with
Dr. Brian Shepard at USC Thornton School of Music. While most
videoconference systems induce latency of a half-second or more, LOLA
has been designed to bring the processing latency down to only a few
milliseconds. As a result, musicians can actually perform together at
The latency recorded for Saturday's duet was 67 milliseconds, meaning
audio and video traveled 2100 miles from Chattanooga to Los Angeles, in
less time than the blink of an eye.
LOLA was connected to the gigabit-per-second fiber optic network built
and operated by Chattanooga's electric power and communications
provider, EPB. The EPB network then delivered the signal to the Los
Angeles studio through an Internet 2 connection.
"This kind of musical collaboration is only possible with very
high-speed Internet networks," said Brian Shepard, Associate professor
of Pedagogical Technology in the Thornton School of Music at the
University of Southern California. "LOLA uses 500 Mbps
(megabits-per-second) to operate, while most so-called broadband
connections range in the 2 -10 Mbps range," he said.
The long distance duet was a collaboraton among the Annenberg
Innovation Lab at the University of Southern California, The Thornton
School of Music at the University of Southern California, EPB Fiber
Optics, the University of Tennessee at Chattanooga, Nashville's "Music
City Roots" live variety show and RiverRocks Chattanooga.

In 1935, the City of Chattanooga established EPB as a nonprofit agency
to provide electric power to the greater Chattanooga area. Today, EPB
remains one of the largest publicly-owned electric power distributors in
the country, serving more than 170,000 homes and businesses in a
600-square-mile area that includes greater Chattanooga and Hamilton
County, portions of surrounding Tennessee counties and areas of North
Georgia. Using a 100% fiber optic network as its backbone, EPB is
constructing a Smart Grid, a next-generation electric system that
includes communication capabilities designed to reduce the impact of
power outages, improve response time and allow customers greater control
of their electric power usage. This same fiber optic backbone is
allowing EPB to offer high-speed Internet, TV and phone service to
business and residential customers community-wide. In September 2010,
EPB became the first company in the United States to offer one
gigabit-per-second Internet speed to the entire service territory. www.epb.net
