Over-The-Air TV is using one of a family of standards collectively called ATSC [ https://bit.ly/3l8B0XH ]. In Europe over the air there is a different standard called DVB-T [ https://bit.ly/3cL1U3h ] or (more recently DBV-T2). Cable in the US (at least) uses QAM [ https://bit.ly/3CUg4tr ] which is routinely encrypted, but a subset called Clear-QAM that is not encrypted does exist. Current FCC (USA agency) rules permit encrypting everything on the cable, and companies are moving to do that (sigh).
