ATSC Adopts M-EAS Standard
WASHINGTON -- The Mobile
Emergency Alert System standard was approved by a vote of Advanced Television
Systems Committee membership last night, according to ATSC President Mark
Richer. “It will be published next week,” he said.
In an interview on Monday, ATSC member and Harris Corp. Vice President of
Broadcast Technology Jay Adrick outlined the significance of the standard.
“M-EAS has been the big project for the past year,” Adrick said. “It is a significant
application to mobile DTV that really doesn’t replace, but supplements, the
delivery of emergency messaging to mobile devices. It’s based on the fact that
broadcasters have a very robust infrastructure and that typically where there’s
a major event, the wireless networks nearby go down, because they’re
overloaded, or they go down because they’re fragile and require a lot of
interconnect that usually gets disrupted by the natural disaster or whatever
event may have just occurred.”
Adrick noted that during Hurricane Sandy, 25 percent of the cell sites went down
in the New York City and New Jersey area, while only one television station
went dark, and only for a short period of time. He added that during the
Japanese earthquake and tsunami two years ago, the cellular networks were
devastated while none of the broadcast stations went off the air.
M-EAS technology will be shown at the upcoming NAB convention and exhibition in
the ATSC Tech Zone, the Mobile TV Pavilion and exhibitor booths.
