How can I add a second tv using direct at&t ?

Have been using direct at&t tv on fiber ( if this helps) on Sony tv in family room. Now want to use it on new Sony in bedroom (MBR).

Do I add wiring or is there a box for adding it?

Who do I call for fees and control ( if necessary)?

Can this be done by a user or is tech needed?

Thanks for shining some light on this if possible....
