ATSC 3 / NextGenTV Interactive Features Broke my ADTH Tuner

My ATSC 3 / NextGen TV woes continue.. My CBS affiliate, along with my local NBC station, have enabled interactive content, offering options like on-demand news segments, weather updates, and even the ability to restart live broadcasts. While the potential of this technology is promising, my experience with it has been far from seamless. You can see it in action in my latest video.

For this test, I used the ADTH box, currently the least expensive ATSC 3.0 tuner on the market. This is one of the devices that the broadcast industry is touting as an acceptable device to help people transition to the new standard on a budget.

The interactive features themselves are designed to provide a more dynamic viewing experience. When the prompt appears on a support channel, selecting the interactive option opens a menu where viewers can choose from various content categories. This might include local news updates, weather reports, emergency alerts, and special event coverage. For instance, NBC’s interface included information about the Paris Olympics, although that content was outdated. These features require an internet connection, as they pull in real-time updates from online sources rather than relying solely on the broadcast signal.

However, on my ADTH box, the interactive pop-up became a persistent annoyance. It pops up and stays persistent for a long time on a supported channels. And in the case of my NBC affiliate the interactive prompt prevented me from navigating back to the channel guide without switching to another channel first.

A particularly strange problem emerged when watching unencrypted ATSC 3.0 channels. A persistent large grey play button overlay appeared on these channels, blocking a significant portion of the screen. Oddly enough, this issue did not occur on encrypted channels. The play button glitch is not intentional, but it underscores the broader problem with the current implementation of ATSC 3.0’s encryption system. Broadcasters are misleading the FCC and the public by claiming these cheap boxes are ready for a major broadcast TV transition.

To troubleshoot, I updated the firmware, even trying a beta version. I performed a factory reset, plugged the box directly into my television to rule out HDCP issues, and tried multiple setups. Nothing fixed these problems. The ADTH box, which should be an accessible entry point for consumers into ATSC 3.0, instead became an example of the complications that DRM and unfinished software introduce to the experience.

Despite these issues, I do see value in the interactive features themselves. On-demand access to local news and alerts could be useful, and the ability to restart live broadcasts is a welcome addition. However, the current execution—at least on this hardware—is deeply flawed. The performance lags, interface issues, and DRM restrictions hinder what could be a major advancement in over-the-air television.

Beyond the interface frustrations, there were issues with HDR implementation. My NBC affiliate broadcasts in HDR, but the ADTH box doesn’t seem to tone map correctly, resulting in an overly dark picture. Switching between channels was also sluggish, and once interactive features were engaged, performance slowed down significantly. The delay in accessing menus and content made navigation frustrating, even when just trying to check the weather or local news updates.

With ATSC 3.0’s continued rollout, broadcasters and hardware manufacturers need to ensure that these features work as intended across a variety of devices. If the most affordable tuner on the market struggles this much, it’s hard to see widespread consumer adoption happening smoothly. For now, I’ll keep testing and see if future updates bring any improvements.
