CI-Slot (Common Interface)

If we talk about TV sets, we are referring to a so-called Common Interface or CI slot, which is an integrated socket in the housing of a television that offers you the possibility of inserting a so-called CI module. Encrypted DVB content can be received directly this way. A separate device such as a receiver for playback is not required.

Subscription necessary for legal reception

In addition to the basic CI standard, CI+ is the most widespread standard today. This format provides more options for broadcasters. Most of these systems are designed for the reception of DVB-S channels that you can receive via satellite. In addition, you will also find products that are DVB-T capable. The prerequisite for access is that your device is suitable for processing these signals.

To be able to actually use this option, however, you need a smart card with a registered subscription for the desired content. The plastic card in the classic credit card size is then simply inserted into the module. Afterwards, the TV programmes are activated.

Older CI slots are not suitable for newer modules. Conversely, the use of an ordinary CI module in a device with a CI+ slot may be blocked.

The exact differences between the two types in detail:

CI Standard	CI+ Standard
Many HD channels blocked	Wider choice of HD channels
Recording possible without expiry date	Limited playback time possible
No limit to the recording time	Recording length can be predefined
-	Complete blocking of the recording option
Use in CI+ slots may be blocked	-
-	Use of other smart cards may be locked
-	Fast forward during commercials may not work
-	Dual decryption might be prevented
-	Reception of two signals simultaneously via twin tuner (CI+ 1.4)

Note: Broadcasters can decide for themselves which of these options the channel will include.
