1) Correct. Our units will modulate HDMI inputs and send out the signal as Clear QAM so no STB is necessary, so long as the televisions have RF input decoders built into them.
2) Yes, generally speaking televisions have RF decoders/tuners built into them. Hence why you can plug in RF cable and get a picture without an STB, because they decode Clear QAM(cable) and ATSC(Antenna); which is what televisions have been using for decades; however I would point out that many new models of tv's coming onto the market don't have RF inputs anymore.
The cable companies encrypt their QAM channels, so you would need to use a particular STB which is supported by that cable company.
Our STB supports CLEAR QAM without any encryption.
The easiest way to check if your QAM is encrypted or not, please connect the CAble TV feed to your Tuner TV, if the Tv scans channels OK, then you have Clear QAM, if not your Qam is encrypted and you Must use Cable Tv STB.
There is no other way around it.
