Last week, Weigel Broadcasting met with the Federal Communications Commission (FCC) to present the findings of a study they conducted regarding encrypted TV signals and Emergency Alert System (EAS) messages . They found that the EAS messages were encrypted along with the content, limiting who can actually see it.
In my latest video I detail Weigel’s findings.
For the past two decades, the ATSC 1.0 standard has allowed nearly any television to receive TV broadcasts with a simple antenna. These devices do not require firmware updates or internet connectivity to decode signals; they operate on a settled standard that works immediately upon being plugged in. In contrast, many ATSC 3.0 televisions and tuning boxes require digital certificates to decrypt content. In some cases, these certificates require an internet connection to refresh, creating a potential point of failure during a crisis – especially if the user doesn’t regularly use the over the air tuner on their television.
Weigel’s presentation to the FCC highlighted a documented disconnect between industry claims and technical reality. While some industry groups have previously stated that content protection does not impede the delivery of emergency alerts, Weigel’s testing in Chicago, Charlotte, Green Bay, and South Bend suggested a different outcome. Using both certified and uncertified tuning devices, researchers found that if a device was unable to decrypt the primary television signal, it failed to display the Emergency Alert System (EAS) messages. The emergency information was essentially trapped inside the encrypted signal.
This creates a significant reliability issue. During severe weather events or other catastrophes, internet and cellular infrastructure are often the first services to fail due to damaged fiber optic lines or power outages. If a television requires a handshake with a remote server to decode a local broadcast, the very system designed for emergency redundancy becomes dependent on the infrastructure most likely to be compromised. I observed a practical example of this earlier this year when a certified tuning box failed to decode encrypted channels during a blizzard due to a security certificate error, even though it was marketed as not requiring an internet connection.
The financial and technical barriers to entry are also notable. Currently, ATSC 3.0 tuners are primarily found in high-end television models, leaving low- and mid-range consumers without native access. The third-party boxes that can bridge this gap are subject to a certification process controlled by the nation’s largest broadcasters. This allows those broadcasters to determine which devices are permitted to decrypt the public airwaves, a shift from the open-standard approach that’s been around for decades.
Weigel’s recommendations to the FCC seek to establish several safeguards as this transition continues. They are advocating for the continued requirement of ATSC 1.0 simulcasting for the foreseeable future to ensure the public is not abruptly cut off. Furthermore, they suggested that a minimum of 19.3 megabits per second of bandwidth be dedicated specifically to free over-the-air video to prevent spectrum from being diverted to private data services. Their proposal also concedes that while digital rights management may exist, it should never require an internet connection for decryption, and signal reception thresholds should remain consistent so consumers are not forced to replace existing antennas.
The FCC is now faced with a choice regarding how to balance the revenue desires of broadcasters with the safety requirements of the general public. The data provided by this study offers a specific look at the risks of prioritizing revenue over accessibility. What’s next? Stay tuned!
