Name
: Only used in GUI to easily identify the scrambling groups. Therefore groups should have descriptive
names to enable easy identification at Phase 2 when connecting programs to SCGs.
•
Algorithm
(Scrambling algorithm) option values:
# unscrambled (scrambling for this SCG is actually disabled)
# DVB-CSA-1
# DVB-CSA-2
# DVB-CISSA
# ATIS-IDSA
# AES-ECB
# AES-CBC
•
Scrambling Policy
option values:
# All ECMGs:
Programs connected to this SCG are scrambled only if all ECMGs are
connected
# Any ECMG:
Programs connected to this SCG are scrambled as long as at least one
ECMG is connected
# Always:
Programs are scrambled always. If all ECMG connections are lost, no one
is able to descramble.
•
Fallback
: (Fallback rule) in case Scrambling Policy (defined above) is not fulfilled. Option values:
# Revert to clear: Stop scrambling. Subscribers will receive programs as unscrambled. Also
non-subscribers are able to view the content.
# Keep last CW: Scrambling is continued using the last CW and the last received ECM.
Subscribers are able to continue the descrambling.
•
Crypto Period (sec):
Min. period in seconds for one control word (encryption key). Also ECM generator
can specify a minimum period it supports and in this case larger of these two values is used.
•
Status
(scrambling status) shown as traffic lights, to provide a quick visual feedback.

CAS List
The table is used to assign readable names to CAS-IDs in order to be able to assign them more easily in the
following tables.
Add here all connected CA-Systems. Each CA-System is identified by two IDs, the “CA system id” (
CAS ID
) and
“CA subsystem id” (
Sub ID
)
5
Sometimes both values can be seen combined to a single “Super CAS ID”.
