12.11.6 Possible Alarms
Alarm Description
BISS PAT Error When the CRC of the PAT is not valid then this alarm is raised.
BISS PMT Error BISS PMT Error
BISS CAT Error When the CRC of the CAT is not valid then this alarm is raised.
BISS Program
Already Scrambled
If a packet of a program to be scrambled is already scrambled (indicated
by the scrambling bits), then this alarm is raised. The packet shall not be
scrambled in that case, but scrambling continues for other packets.
BISS CA-Descriptor
found on Input
If a PMT already contains a CA descriptor then this alarm is raised.
BISS Scrambling
Error
This alarm is raised due to errors happening in the scrambling core
(FPGA).
12.11.7 Operation of BISS
12.11.7.1 Setting a Key for Transmission
Starting point: the scrambler sends clear data to the descrambler. Both have their scrambling mode
set to “Standard”, but scrambling is disabled.
Steps:
• The Session Word is entered in the descrambler (odd key);
• Enable scrambling on the descrambler;
• The Session Word is entered in the scrambler (odd key);
• Enable Scrambling on the scrambler (select ON).
12.11.7.2 Setting an Encrypted Session Word for Transmission
Starting Point: Scrambling is not enabled. Clear TS is send towards the receiver.
Steps:
If Injected ID is used:
• Enter the Injected Id in the device, if it is not yet done (normally, the injected ID shall be
defined earlier)
• Select the encryption mode of your choice:
• Injected Id
• Buried Id
• Enter the encrypted odd session word in the decryptor.
• The odd session word is computed by the decryptor and available for use.
