Using the Equipment
• Maximum CAM Components per Service – This field should be filled in with
the maximum components in each service required to be descrambled e.g. for a
set of services where one audio, one video and one data are required this field
will be filled in with 3. The maximum value supported is 72 components. The
actual value is CAM dependant.

In addition, the RX8000 can filter how it uses its CAM slots. The operator can select
the component types that are assigned to the pool of slots allocated for a service.
• Descramble Video – If this box is ticked the RX8000 will set up the CAM such
that the video components for all of the selected services are filtered for
descrambling whilst dropping any other component types not ticked.
Note: The unit CAM will only descramble these components if the CA system is
correct, etc.
• Descramble Audio – If this box is ticked the RX8000 will set up the CAM such
that the audio components for all of the selected services are filtered for
descrambling whilst dropping any other component types not ticked.
Note: The unit CAM will only descramble these components if the CA system is
correct, etc.
• Descramble Others – If this box is ticked the RX8000 will set up the CAM such
that all scrambled non audio and video components for all of the selected
services are filtered for descrambling.
Note: The unit CAM will only descramble these components if the CA system is
correct, etc.
• Decrypt Components Follows Decode – When this mode is activated only the
components being decoded (or selected for pass-thru) will be allocated slots
within the CAM. This is ideal when for example the CAM only provides the
capability to descramble 2 components and the broadcaster only wants video
and one language of audio descrambled and decoded.
Note: This function only applies to the decoded service.
• Enabled Service Limiting – Enable this if the incoming transport stream
exceeds 72 Mbps which is the bit rate limitation of DVB-CI. This will activate a
