’s bulk descrambler is able to
descramble up to 250 services per card. Actual descrambling is performed in
firmware while extraction of the Control Word from the ECMs is done by integrated soft clients provided by the
CA vendors. The bulk descrambler runs on a dedicated module, providing an external Ethernet port used for the
communication between the soft client and the CA server for exchange of access criteria.
The maximum number of ECMs that can be descrambled depends on the processing power requirement of the
CA client.
Currently the descrambler algorithms supported are: DVB-CSA or AES-ECB; but not both simultaneously.
Below are the CA systems integrated with the bulk descrambler module:

Preparing the bulk descrambler module to descramble services requires some initial configuration to establish a
link to the CA vendor’s server. To be able to view the GUI and enter necessary parameters, the correct licenses
must be installed as the bulk descrambler functionality is licensed together with the number of services.
