The Advanced Television Systems Committee today published a new implementation guide for Mobile EAS, which provides a roadmap for stations that are currently broadcasting a mobile DTV signal on how to bring EAS alerts to equipped mobile devices. The guide includes step-by-step instructions on how to both update broadcast equipment and demonstrate the features to local emergency management agencies.
The implementation guide is available for download from ATSC.
Jay Adrick, a former Harris Broadcast consultant and chair of the ATSC M-EAS Implementation Team, said adding mobile EAS to a TV station’s existing transmission equipment can be done at a modest cost.
“It requires no additional RF spectrum,” he says. “It runs with the CAP used by government agencies. And it runs in the background, allowing regular TV programming to continue.”
Mobile EAS is an add-on to mobile DTV, meaning mobile devices will need specialized receivers and be tuned into an application to pickup on the mobile alert.
At this year’s NAB Show, ATSC and the Mobile EAS team demoed the system’s capabilities. Mobile EAS generates a banner alert that individual devices process and display. The system also aims to to include rich media, like radar maps and charts and graphs.
This additional information can come in any forms including rich multimedia content such as HTML pages, maps and images, and video files, according to the guide.
