1.3 What is 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 belong-
ing with the scrambling system.
Common Interface (CI) is the slot on a digitial
receiver into which a conditional access module
may be insterted. The front of the digital receiver
has two common interfaces.
To watch a pay service, you should take the following steps:
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.
3. Insert the conditional access module into a common in-
terface on the front of the digital receiver.
