I no longer can view any tv channels. My tv is Samsung DNIe and model LA32r71BAX.
I stay in an apartment. Apartments usually have a wall aerial socket.
1. Is my TV digital tv?
2. If yes, do I need the apartment management to install a master aerial or something?
Or, do I need an outdoor aerial? Or, can an indoor aerial suffice?
3. If no, I suppose I need to buy a decoder. With a decoder, do I still need an outdoor or indoor aerial?
Your kind advise please. Thanks.
That TV model seems like very old model already, so it can't support digital TV.
You can either get a DVB-T2 digital TV box, or buy a new TV instead. TV nowadays has built in DVB-T2 digital TV, also known as IDTV (integrated digital television), so no need to use DVB-T2 box.
Once you got it, connect it to the aerial port of your wall point.
You can contact your building management and ask if the centralise antenna, or MATV system supports digital TV or not.
If it doesn't support, ask them when will they upgrade the MATV system to support digital TV?
Otherwise, get an indoor or outdoor UHF antenna to receive digital TV signals. Do note that it may not be guaranteed that you will get signal if you use own antenna, depending on your apartment's facing direction towards the transmitter, geographical reasons, nearby obstacles, and others. So if can use the building's centralise antenna, then use that.
