CAM info
CAM menu: Can not be displayed for any type of module
Dec PID
Manually input the elementary PID for decryption.
If there are artifacts in the picture when using a CAM, this value may
influence the clock rate. Determine the maximal and minimal value at whichthe
artefacts occur. For normal peration set the value between the determined
limits.
Decr PID Beispiel:
Auto: Service selection in the Program Menu Service Test 0x1234$
Man** : Additional to the selection in the Program Menue the Elementary
PIDs for decryption must be set in the DecrPID Menu.
Service Test 0x1234$
Audio El. PID 0x0100
Video El. PID 0x0110
For optimization of the CAM resources, it is possible to configure the
Elementary stream PIDs manually, these must be known (e.g. SAT provider)
Normal setting is „inactive“, the PIDs will be automatically detected and the
elementary streams decrypted
PID-Mode
DVB-Filtermodus
select| DVB filter mode …………………….. Programs marked in the column “programs”
will be inserted into the output transport stream. PIDs 0 to -9 will be
filtered out, and PIDs 0 to +9 will be inserted instead.

trans| The input-TS passes the unit directly through. Additionally the PID 0
to -9 the data can be filtered out.
Program
Programme selection
- Das Erste T ………Pgm.-Name; “” = FTA; T = TV
- zdf_neo T* …….Pgm.-Name; “” = FTA; T = TV; “*” = selected
- Sky Cinema#T$ ……..Pgm.-Name; “#” = scrambled; “$” = descramble
- NDR Kultur R ………Pgm.-Name; “” = FTA; R = Radio
The following description is only an example, which is combined from services
of different transponders. It displays the available services.
The services are represented with a consecutive number, followed by the
service name. The symbol “” or “#” are showing the status of the Decryption:
“” stands for FTA (free to air), and “#” stands for an encrypted service. The
next symbol shows the type of service: “T” for TV, “R” for radio. One service
can be selected by pushing the left key, and a “” symbol appears at the right
hand side on the display. By pushing the same key again, the selected service
wil be added to the list for decryption, and the symbol “” will be replaced
by the symbol “$”. By pushing the left button another time, the selected
service will be removed from decryption.
Attention:
If the PID-filter operates in transparent mode (PID-Mode: transp), any service
can‘t be removed from the list, it only can be selected between “*” and “$”.
If the output of one channel is switched off, or the module isn‘t within the
multiplexing mode, no service selection can be done, and all services are
displayed as disabled.

- If „inactive“ displayed, the filter is not active. It is possible to select a PID in the range from 0x0000 to 0x1fff. Is the selected value under 0x0000 the filter will be set to „inactive“.
The inputs with leading 0x must be entered in hexadecimal format. Should no PID filter be used, set the menu PID-0 to „inactive“. Attention: If the settings for the input parameter „Sat-IF“ or „SymRate“ are changed, all filter settings will be deleted and set to „inactive“.
