At NAB someone asked one of the ATSC folks what would happen if the key is compromised and someone didn't connect a receiver to the Internet. The answer was "the receivers have many built in public keys. They should last the lifetime of the device."

Concerning because they could have a situation like with some 4K blu ray discs, your hardware becomes obsolete because DRM requires that cat and mouse game...

Also with some manufacturers believing the lifetime of a device should be less than 5 years and ideally less than 3 years, and are treating software/firmware support in those lifetimes, there's a lot of perverse incentives hidden behind anyone suggesting "for the lifetime of the device". As bad as some of the old cable monopolies were, they were at least sometimes held to Ma Bell's "the lifetime of a device is supposed to be 60 years" standards (which Ma Bell didn't always follow either, but that's another matter). I realize the ATSC exists primarily to sell new standards, but maybe we need ways to get back to longer planning horizons than 3-5 years.
