U.S. Broadcasters are required to provide emergency alerts to their audiences, but many radio stations use IP-based signal distribution — something incompatible with old-style EAS boxes. What is needed is a simple way to interface the real-world over-the-air reception of EAS events, filter and process the messages, and — if necessary — incorporate the alerts into the modern audio-over-IP (AoIP) air chain. Doing this right involves some innovation, but once done well, there are several distinct benefits. Bill Robertson from Digital Alert Systems joins Kirk Harnack to explain how this award-winning implementation works, and why it makes EAS better and more effective.
