The Advanced Television Systems Committee (ATSC) has given its thumbs-up to the Advanced Emergency Alerting (AEA) specification developed by Monroe Electronics as part of the A/331 standard.
With the Dec. 6 approval of the A/311 Signaling, Delivery, Synchronization and Error Protection standard, announced Wednesday (12/12), AEA is now an official function within the ATSC 3.0 suite of next-generation broadcast transmission standards.
More importantly, a core element of next-gen emergency communications capabilities, based primarily on designs submitted by Monroe and supported by broadcasters and industry equipment manufacturers, has been set.
“This is a significant milestone for emergency information capabilities in broadcast technology,” said Edward Czarnecki, Senior Director of Strategic and Government Affairs for Monroe Electronics. “By approving this advanced emergency messaging feature of the standard, the ATSC is enabling broadcasters to leapfrog to IP-based, mobile, customizable, and media-rich emergency notifications to their audiences, with the potential for a range of first responder and public safety services as well. We deeply appreciate the amazing work of those broadcast and consumer electronics engineers from several countries who collaborated with us to establish this feature as part of the standard.”
The ATSC standard’s AEA feature, says Monroe, “will enable a vastly improved user experience for TV viewers when it comes to emergency alerts, whether they’re watching through receivers on fixed screens, mobile phones, or portable devices such as tablets or vehicle-mounted displays.” Furthermore, the feature allows broadcasters to be more than just a conduit for Emergency Alert System (EAS) messages.
“It gives them an opportunity to engage with their viewers,” Monroe notes.
The AEA feature will also provide powerful new options to help public safety officials get more information out to viewers, resulting in a major public policy benefit.
Said Czarnecki, “The Emergency Alert System as we know it today will continue to be used by television broadcasters. However, Advanced Emergency Alerting will both complement and go beyond the narrow confines of today’s EAS. Stations and consumers will benefit from more detailed and useful alert information; media, graphics, and live feeds; enhanced geotargeting; and even personalized notification capabilities — all delivered to ATSC 3.0 receivers in TVs and portable devices like tablets, laptops, and perhaps even smartphones.”
Using the AEA capability in ATSC 3.0, television stations will be able to send detailed, geotargeted alerts and warnings to the general viewing public or even to specific audiences such as first responders. Broadcasters can supplement those urgent messages with rich multimedia elements that make the alerts more informative than simple EAS messages.
In terms of the user experience, ATSC AEA will enable advanced options for interaction, such as allowing consumers to select the type, language, and display mode of notifications. Users will also be able to choose among text, audio, and video alerts, which will be important for those with accessibility challenges.
Now that the AEA specification has been officially adopted as part of ATSC 3.0, consumer receiver manufacturers can integrate this feature set into their product designs. As such, manufacturers could potentially include the AEA feature in television receivers, portable tablets, mobile devices, and home gateway devices.
Taken together, all ATSC 3.0 standards will be the “glue” that enables broadcast protocol to exist in an internet environment, which means better pictures and sound, personalized and geotargeted viewing, mobile viewing, more robust emergency alerts, and the seamless integration of broadcasting programming with other IP-based services.
