6.2.2 BISS Scrambling and Descrambling
6.2.2.1 Key Handling
The unit supports BISS scrambling and descrambling (Mode 1 and Mode E), which is the
simplest form of fixed key scrambling available. The scrambling solution is based on the
standard scrambler card, while the descrambling is based on the bulk descrambler card.
BISS descrambling can also be done via a CAM based system where the
key is inserted using the CAM interface. Detailed explanation on BISS
descrambling with CAM systems is beyond the scope of this manual.
The key handling procedure is identical for both scrambling and descrambling. A key can be
defined and associated with a name, which is the reference used for the stream’s configuration.
Figure 6.10 – Creating a BISS Mode 1 Key
The figure above illustrates a GUI with one existing key named test. The “test” key may be used
both for descrambling and scrambling.
