Television over fiber/coaxial cable

Hello, you have partially understood the situation:
"I can only get TV through my Numericable decoder and it really bothers me..." But you have no choice; it's the NC system that dictates this. Elsewhere, it would be some other box. The advantage of NC is the TV quality since I told you before, NC was a cable TV network; fiber serves as high-quality long-distance transport (better than coaxial). The local distribution is done via coaxial with a cohabitation of the minimum collective service (about twenty free TNT channels that you still pay for in your charges). As a reference, you connect your TNT TV to the antenna socket of the apartment. There's also a mix of NC options that require the NC box. Of course, it's paid! NC is not a charity, and the connected box to the TV allows you to discover the TV options you have chosen. You can also connect your phone and the internet, which can be more or less turbo depending on the location! All of this, of course, comes with your subscription. The Numericable box connected receives TV through a secure digital decoder (smart card), while internet and telephony work like Internet Service Providers, who transmit ADSL information through phone lines. And if you want a second TV, NC can rent you a second terminal!
There you go, we've covered your situation; it's up to you to choose from the options available to you.
Cheers!

Well, I actually did the test by plugging the cable directly into my TV to see if I would still receive the channels, and that's not the case..

So I've more or less answered my question, my original TV cable seems to have been replaced by the new socket connected via coaxial cable. So, I can only have TV through my Numericable decoder, and that really bothers me...

Could someone tell me if it is still possible to connect to the TV antenna cable, and if so, how? (I imagine I should have asked the technician to install the new socket with dual input and to add a second one just for my TV...)

Again, thank you to those who can enlighten me!

The operator, whoever he is, makes his job easier by using the coaxial cable that is normally used to distribute the DTT within the building; the problem is that the DTT is no longer available when the box is connected this way. The issue is that when the subscription is canceled, no one comes to reconnect the coaxial cable to the DTT! This is an unspoken way to try to win back customers by the same operator...

I have a follow-up question and thank you for giving me advice: I just got the same fiber installation yesterday, but my husband made a branch from this coaxial cable to power the kitchen TV and bedroom TV, and now nothing works since the branch is cut!!! How to "power" the two other TVs with just the basic channels???? No one can answer us. SFR says: "you need to run another cable," but apparently, there is no space in the duct to bring a cable from the technical closet in the hallway...

Hello,
As part of a building, a new cable must be run from the technical shaft to separate the 2 networks, no matter what, if we want to switch to the collective TNT.
Otherwise, rent additional decoders for each TV, to be discussed with the operators.

It is necessary to install amplified antennas to receive the terrestrial TNT signal. It's not complicated to say.

Thank you very much for your quick response, Bernorenard, however, I feel like we veered a bit off-topic and I'm not sure I got an answer to my question. So, I will restate my problem.

I don't know much about internet networks, so I've informed myself as much as I could: I’ve understood that different operators do not operate in the same way.
As far as I’m concerned, from what I understood, Numericable does not bring the "fiber optic" itself directly to the apartment (as Orange, SFR, or Free do) from the common areas, so they don't need to drill a hole from the hallway to the apartment to bring in the fiber. They use the existing cable already in my apartment that allowed me to receive TV (on my television that has a built-in TNT decoder).

That’s what the technician did at my place; he only changed the socket (replaced with a double screw-in socket, as I explained previously). I now have my Numericable decoder plugged into one of the inputs and my modem plugged into the other.

My question is: did the technician use exactly the same cable that was already in my apartment to bring in the fiber, or was it another cable that was already present in my apartment but was unused?
Basically, I want to know if I can continue to connect via the new coaxial cable directly to my TNT tuner TV, or do I have to go through the decoder? In that case, would that mean that if there is a problem with the Numericable network one day, I can no longer connect to "regular TV" via the antenna?

I hope I have been clearer; I admit that I'm lost with this story of fiber coming through coaxial cable... I don't understand if my "TV cable" has disappeared or if I can simply use the new one for the same purpose...

Sorry for the length of this request, and thank you in advance for any responses!

I see that the technical level of the speakers is quite low?
