APPENDIX A - CONDITIONAL ACCESS WORKED EXAMPLE
BISS-E uses four access codes for each transmission. Two of the codes are held in the
receiver and two in the transmitter. Each pair of numbers is used in a calculation to
create a key for the transmission – this key must be the same at both the transmitter and
receiver (i.e. the two numbers may be different but the calculation result must be the
same).
In each unit, one of the codes is factory set (BISS-E injected identifier) and one can be
set from the front panel (session key).
The video exciters use the unit serial number repeated twice to create BISS-E injected
identifier.
Examples
Unit serial number 1234567 Code: 12345671234567
Unit serial number 2018888 Code: 20188882018888
1. On the video exciter, navigate to the main operation menu. Set the following
parameters:
Frequency 950.0000MHz
Symbol rate 6.5000Msym
FEC ¾
2. On the video exciter, navigate to the Video menu. Select the correct video source for
the system.
3. On the Alteia, navigate to the Input menu (#4). Set the following parameters:
Frequency (menu 4/11) 950.0000MHz
Symbol rate (menu 5/11) 6.5000Msym
FEC (menu 5/11) ¾
4. On the video exciter, set the carrier and modulation (Tx key) to ON.
Step 1 – verify signal
The LOCK LED on the Alteia should now turn green and video should be seen on the
monitor.
Step 2 – set up CA on the video exciter
1. On the video exciter, navigate to the SCRAMBLING menu. Set the following
parameters:
Conditional access mode BISS-E.
Key 1000000000000000
2. On the video exciter set the conditional access (CA key) to ON
