Until ATSC 3.0 is forced on everyone, at least if you're in the USA :/
ATSC 3.0 is the next version of the protocol used for over-the-air digital TV in the USA. It has some good parts, for example it uses H.265 instead of MPEG2 which allows for 4K TV at lower bitrates to what 1080p uses today, and 1080p at significantly lower bitrates.
However, it also supports DRM and encryption, and all the major networks are already encrypting their broadcasts. TVs need an internet connection to get the decryption key, and can't store recordings in a decrypted format.
