While using descrambling by DVB-CI cam, the user needs to set some initial parameters under the
System
tab to control the CAM, as shown below.
4.4.1. CA Descramble
CAM Enable:
This field allows the user to enable or disable CAM module.
Multi Service Mode:
This field allows the user to choose the CAM type if it is single service CAM
(Disable) or multi service CAM (Enable).
Select Maximum TS Bitrate:
This field allows the user to define the maximum TS bitrate the CAM can
handle. Since each CAM has different clock rate, this control will allow the right clock to the right TS
bitrate and CAM capability.
CAT Info Pass Through:
This field allows the user to pass the CAT information to the output ASI
(Enable) or block the CAT information from the TS output (Disable).
After the initial setup of the CAM in previous section, user can move to
Descramble
page and follow
the below steps:
1. Select a specific service user wants to descramble from a drop down menu under
Program
