What really? Or does it only differs and depens thru hardware or dongles? On Live Channels apps, what can they support? Do they still support NTSC analog? How about ISDBT? Does it depend thru Android TV versions?

Whatever the tuner integrated inside the device supports. Android TV itself is pretty agnostic since the tuner delivers already decoded stream. Here in Europe, DVB-T/2, DVB-C and DVB-S/2 is pretty standard with analog being more or less gone. In US I'm guessing you need to check what the device itself supports.
Android TV is just the interface. It depends on the hardware manufacturer.
Maybe you would get more meaningful answers if you mention your country??
there is no analog, fundamentally it all depends on what codec support your device has. 264, mp4, and mp2 will get you far.
if you're asking about devices with tuners, they are demodulating (and digitizing in the case of ntsc) the signal into some codec media stream (container/transport formats aside), so whatever the tuner specs are. astc/qam/etc
live channels app is it's own thing.
It'll take whatever your tuner gives it.
It supports a limited number of ATSC USB devices, and that's it. No NTSC, no DVB, and no ISDB. You can get IPTV with some third-party software like TVirl but they all have major flaws like no subtitles, no guide, no dual audio, no recording, and don't get many/any updates.
You might be able to get something like a HD Homerun to work. They have a product but I haven't tried it. I did try with the tvheadend integration, never got it to work.
That's going to depend on your tuner hardware, if there are drivers and the tuner presents a v4l api you should be good to go. If the tuner isn't supported, you can always try something that spits out iptv streams like nextpvr or tvheadend, and import with a plugin.
