to be received by only one specific receiver, use the buried ID to calculate the encrypted session
word (SW).
Injected ID
: An identifier can be entered (injected) in a receiver (IRD), this injected ID can be
entered in a single or a group of IRDs. This allows a
BISS-E
protected transmission to a group of
IRDs.
Operation
BISS Mode 1
: Connect the scrambler between the encoder and modulator. Select the
output interface rate (must be equal or higher than output interface rate of the encoder). Select
BISS Mode 1. In case of BISS Mode 1 with clear session word, enter the 12 digit session word
SW
.
Communicate the session word to the receive site(s).
Operation
BISS Mode E with Buried ID
: Connect the scrambler between the encoder and
modulator. Select output interface rate (must be equal or higher than output interface rate of the
encoder)- Select BISS mode. In case of BISS Mode E with Buried ID, get the Buried ID of the IRD and
use this together with a session word to get calculated the

ord (using the DES3
algorithm). Communicate the ESW to the receiving site.
Operation
BISS mode E with injected ID
: Connect the scrambler between the encoder and
modulator. Select output interface rate (must be equal or higher than output interface rate of the
encoder). Select BISS mode. In case of BISS mode E with injected ID, get the injected ID of the IRD(s)
and use this together with a session word to get calculated the encrypted session word (using the
DES3 algorithm). Communicate the ESW to the receive site(s).

Mode 1
Under Mode 1, the BISS scrambler applies scrambling by a fixed Control Word (CW), derived from a
clear SW (Session Word). In Mode 1, a fixed 12-character SW is inserted into the scrambler. The
64-bit CW is derived from the SW according to DVB-CSA specifications. The User can select Mode 1
in the drop-down menu, and then input the descrambler key. The descrambler key consists of 12
characters based on the Hexadecimal system from 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. The
IRD-6100 descrambler key is equal the SW Data on the BISS scrambler side.
After inserting the descrambler key, the user should press “Set” to start descrambling. A few
seconds later, the programs will be descrambled.
Mode E
Using Mode E, the BISS scrambler completes scrambling through the
ESW
value and
ID Select
. The
ESW value is equal to the Descrambler key on the IRD side, while the ID Select equals the Burned
Key on IRD side. The BISS scrambler ID Select has two options: Device and Input. If Users choose
Device, the Burned Key needs to be selected when descrambling, while if users choose Input and
set Input data, on IRD side, users do not need to select Burned Key and input the Input data as SK.
Under Mode E, users can select Burned Key option or not. Under Mode E, the device will calculate a
new date which works as descrambling key. The new data is created by Descrambling Key (refers
