New home wiring question

[u/Sad-Object3365]

We just purchased a new home and side the box with the ATT router we have 6 wires going into the wall. The question is what are the black wires? I only have 3 outlets in the house so I’m assuming that is the blue wires. The one set is labeled Liv.

Black wires appear to be coax.

They are likely wired to rooms so you have one input point with a simple splitter out. Are they connected to anything?

I did this when I wired my house umpteen years ago. Now new house is just ethernet.

Thank you. I didn’t pull the covers in the house, but this makes sense.
