The checkboxes in the "Descramble" column are used to select services for descrambling by CA module. Several services
can be selected, if the module supports simultaneous descrambling of several services.
The "Descrambling status" icon meanings: - service is descrambled successfully, - service is not descrambled.
7.3.4. Detailed service information
Press the icon at the start of the list of services line. The detailed service information table will appear:
Figure 15. Detailed service information
This table is used to see the detailed service information and select individual streams for descrambling and output stream.
The following service information is shown in the table: service title, service provider, service id, PMT (program map table)
PID, types and PID-s of service streams, PCR (program clock reference) PID, New service title, New service provider, LCN
(logical channel number). After checking the "Descramble" checkbox of service line, all streams of this service are included
in a descrambling list of the CA module. Unnecessary streams can be deselected from the descrambling list by unchecking
corresponding "Descramble" checkboxes of streams. Close the table by clicking on the icon. "New service title" - the
name given to the service. The name that the service has on the input transport stream is the default name. Also this name
will be used as the output service name."New service provider" - enter the provider name of the output stream. This name
will be used in the SDT table.LCN: Logical channel number for outputted TS can be placed.
NOTE: PMT tables are not regenerated, so even if service is descrambled, some TV's might show "service scrambled"
message, because CA descriptors are left at PMT table.
7.3.5. Output settings
RF output - On/O turns on o RF output.
Constellation - modulation scheme of the output signal. Possible values of the
modulation scheme: QPSK, QAM16, QAM64.
Code Rate (FEC) - There are ve valid coding rates: 1/2, 2/3, 3/4, 5/6, and 7/8.
Guard interval - guard interval of OFDM signal available selections:1/32, 1/16, 1/8, 1/4.
Modulation mode - modulation mode of the output signal. Values: 8k or 2k.
Output frequency - values from 170-230/470-860 MHz
Output bandwidth - the bandwidth of DVB-T transponder. Can be selected from values
8 MHz and 7 MHz.
RF level - OFDM signal attenuator control Can be selected from values 0-(-15) dB.
Once the dierent data values have been entered, click on Update to conclude the
Output settings.

7.3.6. TS output
Several tables related to NIT generation exist in this section. „Global TS
parameters“(Figure 17) describes following TS parameters:
“NetworkID” is unique within the geographical region dened by the “country code”.
For a cable network, usually this is a single country code plus 0x2000 (8192). If
there are more modulators in the network, they must have the same Network ID.
Proper value depending on your country and operator can be found here:

“Private data specier” (in hex format) can be inserted in the NIT table for proper
LCN description. This value is described in TS 101162 specication. Valid value
for each operator can be found here:
http://www.dvbservices.com/identiers/private_data_spec_id?page=1
„Network name“ is the name of the network.
