Four PBS Stations Named to Run Mobile DTV Emergency Alert Pilot Test
November 30, 2011
WASHINGTON: Four PBS member stations in far-flung markets
will be the first to participate in a pilot test of the Mobile DTV emergency
WGBH-TV in Boston, KLVX-TV in Las Vegas, and Alabama Public Television stations
WBIQ-TV in Birmingham and WAIQ-TV in Montgomery will participate in the program,
funded by the Corporation for Public Broadcasting and LG Electronics. LG is a
primary manufacturer of receivers that decode ATSC M/H, the transmission
standard for mobile broadcast digital television.
“If we’re successful, the results of the pilot will help usher in a new era of
mobile alerting systems. They will be extremely valuable to federal, state and
local emergency management agencies and the publics they serve and will extend
the community service role of public and commercial broadcasters alike. We
welcome the leadership of PBS stations to serve as the ‘test bed’ for these
rich-media emergency transmissions,” said Dr. Jong Kim, president of Zenith
R&D Lab, the U.S. research and development subsidiary of LG.
PBS announced its intention to test a next-generation EAS system this year
during the NAB show in April in Las Vegas. The goal is to feed EAS information
to platforms of all types, from cellphones, tablet computers, laptops and
netbooks to in-car navigation systems. The new Mobile Emergency Alert System
will comprise video, audio, text and graphics.
The mobile system, like the fixed EAS broadcast network, will be a platform for
AMBER alerts and photos of children and their alleged abductors, emergency
information, including maps and escape routes, live video and other details.
“This goes way beyond just a text message on a congested cellphone network,” said
John McCoskey, chief technology officer at PBS. “It’s harnessing the power of ‘one-to-many’
transmissions from a TV broadcaster to the viewing audience.”
Cellphone service providers announced last May they would launch emergency text
alerts in New York City by the end of this year. The Personal Localized
Alerting Network works only on GPS-enabled smartphones for three types of
alerts: Presidential, life-threatening and AMBER Alerts. PLAN enables service
providers to push texts of 90 characters or less to specific cell towers.
AT&T, Sprint, T-Mobile and Verizon agreed to participate, though they can
opt out of all but presidential alerts since the program is voluntary for
McCoskey said the goal of the M-EAS project was to develop a system that can be
“easily replicated by both public and commercial broadcasters throughout the
country.” Since ATSC M/H incorporates Internet Protocol, it has the flexibility
of streaming, data and non-real-time delivery as well as live broadcasting.
The date of the pilot program launch was not announced.
