Yes, exactly, the guy who came last year inserted a cable into the wall socket and said the building is digital-ready. I don't have
cable TV, although other people in this building have it. My neighbour had it and had a huge antenna on his balcony (of the same size as a rooftop antenna).
I think the guy who came last year had said I didn't need an antenna, and that I only had to insert a coaxial cable into the wall socket... The guy I asked yesterday in the shop was honest and said he doesn't think it works without a rooftop antenna, but after all the shop was a computer shop and he might not know 100%.
Maybe I will ask the landlord too.
I could get a box, but my TV is old and I wouldn't even have enough free channels... They said a box (here) is about 100 bucks, and a digital TV of the same size as my TV would be something under 200, about 170-180, tuned to all new channels. So I think it is better for me to get a new one altogether. I had thought of the USB stick as an alternative, as the TV room is freezing cold in winter, and with a USB stick I could watch TV in bed when there is something good (unfortunately not very often anyway...
