6.2 Bulk Descrambling
Sencore’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:
CA System Number of Services Supported
BISS 250 services
Latens 250 services
Verimatrix 250 services
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.
