Figure 3.67 Service Plus Interface
On the Service plus page all of the services within the Transport Stream are
displayed. Each of these services has some information and some control fields. To
select a service for decryption, select the service required from the list and tick the
Decrypt box then press Apply.
Multiple boxes may be ticked, however the CAM will only decrypt up to its maximum
allowed services / components.
3.11.2.7.3 Setting up the CAM
The CAM does not report how many services or components it is capable of
descrambling, this must be manually configured on the RX8000 by the user. To do
this the following fields need to be configured:
• Maximum CAM Services – This field should be populated with the maximum
number of services the CAM can decrypt. The maximum value supported is 24
services. The actual value is CAM dependant and this information should be
supplied by the CAM vendor. In the case where the CAM vendor only supplies
the number of components the CAM can handle (sometimes called slots) the
number of services can be calculated as:
Services = Slots / Components per service to be descrambled.
Note: When calculating components, if VBI components are required then this
may take one or more slots.
• Maximum CAM Components – This field must be populated with the maximum
number of components that the CAM can handle (sometimes called slots). The
maximum value supported is 72 components. The actual value is CAM
dependant.
