1.6 CI (Common Interface)
Some broadcasts are scrambled so that only paid subscribers can enjoy
them. Scrambled services can only be viewed with a Conditional Access
Module (CAM) and a subscription card belonging with the scrambling
system. Common Interface (CI) is the slot on a digital receiver into
which a conditional access module may be inserted. The front of the
digital receiver has two common interfaces.

① 1. Purchase a conditional access module and a
subscription card for the pay service you want to watch.
2. Insert the subscription card into the conditional access module.

front of the digital receiver.
