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).

Really?

RTL-SDR.com has nice explanations and software listing also for beginners (who may not have Google to use).

Hope I can get an answer  ...  Does anyone have software that can decode Over the air TV signals using SDRPLAY ?    Seems like there is software out there to decode almost any mode of signal in the HF Band.
