Operation Manual 12./07 WISI Communications GmbH & Co. KG
The content of the CA descriptors of the CAT will change immediately (within 500ms). The
contents of the CA descriptors in a PMT will only change when the corresponding services
switches from clear to scrambled. If you use Save&Reboot after the whole setup, you can be
sure, that your private data will be used.
Please note: There is no need for private PSI data, if your head end conforms to the DVB head
end standard.
ATTENTION!
You have to take care by yourself, that the size of the PMT section
containing your private data and all CA descriptors does not exceed the maximum
size when using private data.
3.14 Global PID mappings Page
This page enables the administrator to define PID ranges to be used for placing ECM and
EMM PID´s. The scrambler supports up to 4 ECM generators and up to 256 Scrambling
Control Groups. Therefore the scrambler needs up to 1024 (free) PID´s to be used as ECM
PID´s.
The PID´s will be automatically assigned by the scrambler after a successful scan. The
scrambler tries to allocate the PID´s in the given ranges, taking PIDs into account, that are
already in use. The scrambler analyzes the PAT, CAT and PMT´s during the scanning to find
PID´s, that cannot be used as ECM or EMM PID´s.

3.16 Service List Page
The Service List page lets you scan the services of the transport stream applied to the ASI
Input of the scrambler.
The look of the services page differs, depending on the number of scanned services. If no
services are scanned, then the services page notifies you about it like shown below.
