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
belonging with the scrambling system.
Common Interface (CI) is an interface for condi-
tional access modules. The front of the digital
receiver has two common interface slots.
To watch a pay service, you should take the following steps:
1. Purchase a conditional access module and a subscrip-
tion 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 to a common inter-
face slot on the front of the digital receiver.
To view the information about
the module and subscription
card inserted to the digital re-
ceiver, select the Common Inter-
face menu.
