Although you are in the countryside, you also need to transform digital TV. Therefore, every terminal needs a set-top box in the future, and the signal cable TV operator will help you consider it. You only need to install a weak box for each household, and pull coaxial cable and Category 5 cable from the weak box to the point where TV is used, and pull Category 5 cable to the point where computer is used. Remember that the weak box should have power supply. That will do.
