How to make analog TV digital?

You don’t have to buy a new smart TV to switch to a digital network. By just using a normal set top box instead of your cable connection, you can change your analog TV to a digital TV.

Either you can contact your existing cable operator to provide you a set top box or you can subscribe to D2H or Direct to Home services offered by Airtel Digital TV, Tata Sky, Jio TV, etc.

NOTE: A set top box helps in converting digital signals into normal content that we can watch on TV. DTH is the connection which sends these digital signals from a satellite to the set top box.
