The article will explain a bit about the 'Network Tab' in the GUI.



This tab is important, if you want to control/edit:

  • LCN / HD LCN
  • DVB-T
    • Network ID
    • Network Name
    • NIT Standard
    • EIT Settings
  • DVB-C
    • Network ID
    • Network Name
    • NIT Standard
    • EIT Settings
  • IP
    • EIT
    • EIT Barker channel
  • Shared
    • CAT
    • Static NIT
    • Manuel TS ID



LCN / HD LCN


By using Logical Channel Number (LCN), you can 'remap' the program number used (Service ID), to another location. The role of the LCN is to enable user presentation of service numbers, in a convenient and familiar form. This is done, by using a private descriptor field (0x83) in the NIT.


The intended use

If a channel is send through TDX in both SD and HD formats then the configurator can assign the same value as an LCN number to the SD channel and as an HD LCN number to the HD Channel.

For example, if we are sending "Kanal 5" and "Kanal 5 HD" then we can assign LCN number 12 to the SD channel and HD LCN number 12 to the HD Channel. Now a compatible STB that supports HD channels will put "Kanal 5 HD" at number 12 and ignore "Kanal 5", otherwise "Kanal 5 HD" will be ignored.


Please note: There exist very few STB that support HD LCN at the moment. So it’s better not to use it if the customer don’t need it.







DVB-T / DVB-T

Network ID

(Default value: DVB-T: "12289" DVB-C: "40961")

DVB-T : 12289 converted to HEX, is 0x3001. This number is within the re-useable range of network ID's for "Countries of Colour A".

DVB-C : 40961converted to HEX, is 0xA001. This number us within the re-useable range of Cable networks.

Network name

(Default value: "TDX-NET")

Network name is used to transmit the name of a physical network, e.g. "ASTRA", "EUTELSAT", "MUNICH CABLE"
etc. This descriptor shall be used exactly once in the first descriptor loop of any NIT sub-table.


Orig. network ID

(Default disabled)

This field gives the label identifying the network ID of the originating delivery system.


NIT Standard

(Default set to "DVB")

"Nordig" is available. The Nordig standard supports over-the-air downloads. To use this, the data services must be available throgh the TDX/TDH800.


EIT

(Default value set to  "Full Actual - Full Other")

EIT delivers the data for the Electronic Program Guide (EPG). As default, full EPG is available for current and other services on DVB-T out.

'Actual' means the MUX itself. EIT for this specific MUX contains, in example, Full EPG about the services in this specific MUX.

'Other' means, all the neighboring MUX's. EIT for all the other MUX's , in example, could be limited to present/following EPG


Available options are:

Option
Description
Full Actual - Full Other
Full EPG for all services, on the current MUX.
Full EPG on other MUX's also.
Full Actual - P/F Other
Full EPG for all services, on the current MUX.
Present/Following EPG on other MUX's.
Full Actual - No Other
Full EPG for all services, on the current MUX.
No EPG on other MUX's.
P/F Actual - P/F Other
Present/Following for all services, on the current MUX.
Present/Following EPG on other MUX's.
P/F Actual - No Other
Present/Following for all services, on the current MUX.
No EPG on other MUX's.
No Actual - No Other
No EPG at all (disabled)
Barker Channel
Depending on the Barker channel data




IP Settings

EIT

(Default value set to  "Disabled")

EIT delivers the data for the Electronic Program Guide (EPG). As default, full EPG is available for current and other services on DVB-T out.

'Actual' means the MUX itself. EIT for this specific MUX contains, in example, Full EPG about the services in this specific MUX.

'Other' means, all the neighboring MUX's. EIT for all the other MUX's , in example, could be limited to present/following EPG


Available options are:

Option
Description
Disabled
No EPG at all
Full Actual - No Other
Full EPG for all services, on the current MUX.
No EPG on other MUX's.
Barker Channel
Depending on the Barker channel data



The EIT barker channel can be output in two ways depending on how you distribute your IP output:
 

IP output method
Barker channel distribution method
IP output is distributed through the Link sockets.
EIT barker channel is output through Link 2 on the main unit
IP output is distributed through an IP output module.
EIT barker channel is output through the AUX socket on the first IP output module in the headend system


 


EIT barker IP address

(Default value set to  "0.0.0.0")

The IP address, on which you want to receive the Barker channel.


EIT barker IP port

(Default value set to  "50176")

The port number, on which you want to receive the Barker channel.





Shared Settings

These settings apply to all output (DVB-C, DVB-T and IP Out).


Manual transportstream ID

(Default disabled)

On QAM and COFDM output modules, the Transportstream ID is predefined and locked to the position/slot of the module+MUX number. The following is from a QAM output module.



In example, a QAM module in slot 1 will give the 4 MUX's transportstream 10, 11, 12 & 13. 


If you want to overrule these ID's, you need to enable this function.


Use static NIT version

(Default disabled)

When changing the output signal on the headend, in anyway, the NIT version is incremented (between 0 up to 31).



If you don't want this, if you want to keep the same version on the NIT, you can enable this function. The initial value

is '0'.


Enable CAT tables

(Default enabled)

The CAT provides information on the used Conditional Access System(s),the PID of the corresponding EMM (Entitlement Management Messages) flow and any parameters for these systems.


Removing this option, disables the pass through of CAT.
