Verimatrix Bulk descrambler extracts Operator ID from ECM and compare
against configured value:
•
It rejects ECMs if Operator ID is set (not 0) and is different to the
value configured
•
It accepts ECMs that match the Operator ID indicated in the
configuration, using these ECMs for descrambling
•
Verimatrix descrambler will raise an alarm if no ECM has been found
with the configured operator id: "Warning: Operator ID field not present in
incoming ECM’s.
Extraction of ECM Operator ID only guaranteed as long as Verimatrix doesn't change their
ECM format

Key Handling
The unit supports BISS and BISS2 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.
The figure above illustrates a GUI with one existing key named
“
test
2 chck”. The “test
2 chck
” key may be used
both for descrambling and scrambling.
