A debate is escalating between the National Association of Broadcasters and vendor Digital Alert Systems (DAS) over the future of the Emergency Alert System, specifically whether the Federal Communications Commission should allow software-based alternatives to the traditional hardware used by broadcasters. In recent reply comments to the FCC, NAB pushed back strongly against DAS’s objections, calling them “doomsday warnings” and accusing the company of being the lone detractor in an otherwise united front.
The NAB has long supported a move to virtual encoders and decoders, arguing that stations should have the choice to transition away from one-box hardware devices. Their position is bolstered by Sage Alerting Systems, the other major EAS vendor, which supports the transition and plans to phase out its hardware production due to parts shortages. Sage called the move to software “long overdue,” emphasizing the practical benefits of flexibility and modernization.
Broad support for the software option has come from public broadcasters, engineers, cable companies, and manufacturers. The Society of Broadcast Engineers added that a virtual approach would reduce the need for costly, time-consuming physical repairs by contract engineers. NAB noted that it first raised the software proposal with both Sage and DAS in 2021, but only Sage engaged in constructive talks.
NAB insists that its proposal wouldn’t remove hardware entirely but would allow stations to choose what works best. It criticized the idea of waiting to submit a perfect, all-encompassing rulemaking petition as a stalling tactic. “EAS is the last link in modern broadcast air chains that remains stuck in a hardware world,” NAB wrote. “It is long past time for the Commission to allow EAS to similarly evolve into a software-based environment.”
DAS responded forcefully, defending its position as a thoughtful contribution to a serious technical discussion. Company vice president Edward Czarnecki said their concerns include cybersecurity, timing accuracy, and network isolation—issues not fully resolved by proponents of software EAS. DAS also noted that it already offers software-based tools, such as its HALO monitoring system and Collector ingestion platform.
While reiterating a willingness to work with all stakeholders, including NAB and the FCC, DAS emphasized the importance of “rigorous discussion, technical vetting, honest disagreement, and earnest compromise” before changing the foundational requirements of the nation’s emergency alert infrastructure.
