The Common Interface (CI) is the slot on a digital television receiver into which a conditional access module (CAM) may be inserted for satellite television. Receivers normally have two common interfaces. A receiver with a common interface allows the user to access encrypted television broadcasts as opposed to free-to-air (FTA) channels.
CI (Common Interface) also allows you to type the keys in through the Viaccess option, so without buying a subscription card, you can receive the encrypted channels by registering their keys in your receiver.
