Ads, ads everywhere.
Besides there, there is also a 4k OTA standard, ATSC 3.0. Most TVs don't support it yet, but some do. Worth googling before you buy. You can also get something like an silcondust 4k standalone tuner and plug that into your home network instead. You then load its app to watch over the air TV in 4k.
If you do buy the silicondust tuner, you can go further and get a DVR going. Plenty of free projects that will help you setup and record TV like jellyfin, and many of them will auto-skip the ads too with an application called comskip.
Atsc 3.0 requires an internet connection for it's bullshit DRM
Woww, over the air broadcasts with copy protection? 🤮
It's like they want OTA TV to die off.
That seems entirely pointless then, why not just stream the content.
Bandwidth is cheaper from the tower since the signal is the "same" for each client and it can then be distributed over a wide area. You send the "DRM" (Just a fancy encryption key) over the network since it's relatively small and likely unique to each device (probably fingerprinting the device ids to the content invisibily in case of piracy).
Multicast is a thing, though it doesn't seem to be widespread. That would make a lot more sense than this weird DRM broadcast system.
Multicast still requires more expensive less widespread bandwidth than sending out analog signals ota & shooting off a few packets of encryption information every now and then. US infrastructure has rapidly improved over the past few years, but we're still a farcry from anything robust and reliable enough to serve the people benefiting from this type of content.
Having the receiver phone home would have the benefit of generating more accurate viewership data, where broadcast tv has historically relied on representative cohorts.
No OTA broadcasts in the US utilize 4k yet. ATSC 3.0 is being utilized some, but not exclusively, but no one is broadcasting 4k unfortunately
