Digital TV with no co-ax cable. Only Internet.

[condo bought]

I live in BKK.

I know nothing about Digital TV.

Other than I have one. In my mancave office.

48 inch LED that I use as my computer monitor. It's listed as being a fully-digital TV.

The TV cable (co-ax) for the house is in an other room downstairs. Would be inconvenient to run the cable up to my office/mancave.

Is it possible to buy one of these digital TV boxes that you see for sale for a thousand baht or so, and hook it up to my TV without the co-ax cable, and run through my internet or whatever (Internet is wi-fi but connected to my PC by dsl cable (or whatever it's called)?

Or does it need to be connected to the house's co-ax cable and then to my TV?

Thanks.

You might be able to get by with a small indoors antenna, like this:

But first you'd need to make sure your TV supports DVB-T2, and it will only work if you're in a good signal area because it's only a small amount of gain.
