Common Interface CI+
Together with this platform, an extension to the Common
Interface (CI) Conditional Access system is added, called CI+.
CI+ or Common Interface Plus is a specification that extends
the Common Interface (DVB-CI) as described in the digital
broadcasting standard DVB.
The weakness of the conventional CI module as Conditional
Access system was the absence of a Copy Protection
mechanism, as decrypted content could be sent over the
PCMCIA interface unscrambled. With the CI+ extension, a
form of copy protection is established between the Conditional

Ambi Light
The Ambi Light architecture in this platform has been entirely
renewed. The characteristics are:
•
Additional DC/DC board generating 12/16/24 V (optional)
•
ARM processor (on DC/DC panel or AL board)
•
Low-power LEDs
•
SPI interface from ARM to LED drivers

Access Module (CAM) and the Integrated Digital Television
(IDTV). The security mechanisms in CI+ are derived/copied
from POD (with the exception of Out Of Band (OOB) used in
US CA systems). For more information about conventional CA
systems using a CI module, refer to the BJ3.0E L/PA or BL2.xU
Service Manual.
The CI+ standard is downwards compatible with the existing CI
standard.
The following figure shows the implementation of the CI+
Conditional Access system in the TV543 platform.

The use of the DC/DC board is optional. In case no DC/DC
board is implemented, the ARM processor is located on one of
the AL boards.
