Scrambling Tab

This tab allows to enable scrambling via external Eis.

By default, scrambling via Eis is disabled for multiplexing services.

To enable scrambling via External Eis tick the corresponding box.

Info: Existing SCGs will be disabled on any output where external Eis is enabled.

These settings are only for advanced configurations. Default values should be suitable for the majority of use cases.

Parameter name	Description	Possible values
Minimum bitrate modifier	Controls the next minimum bitrate for each statmux interval. Lower values results in faster bitrate decrease	Floating point values between 0.1 and 1
Scrambling Algorithm*	Chosen Scrambling Algorithm Version. Changing it on a running service requires a service restart.	Dropdown menu: CSA V1 48bits, CSA V2 64bits, BISS Mode1, BISS Mode2, CISSA V1 TS Level, CISSA V1 PES Level, AES-ECB, BISS CA, Director 6
Behaviour until all required ECMs for SCG first received	Choose how to output until all scrambling information is available.	Dropdown menu: Component(s) in SGC not present in output TS, Component(s) in SCG in-the-clear inn output TS

To add information about a vendor, click on the corresponding + Add Vendor button.

Parameter name	Description	Possible values
Name*	Name of the vendor. When the configuration is saved, the name will appear as title of the vendor panel. You can use the arrow on the right to collapse or expand the panel for easier management of multiple vendors configuration.	String of max 32 characters

Details about the parameters available for the different tabs in the following paragraphs.

Parameter name	Description	Possible values
Network interface	Name of network interface used for the ECMG communications	String of max 32 characters
Primary address*	An IPv4 address for the primary ECMG	IPv4 address string
Primary port*	Port number for the primary ECMG	0 to 65535
Secondary address	An IPv4 address for the optional secondary ECMG	IPv4 address string
Secondary port	Port number for the optional secondary ECMG	0 to 65535
Super CAS ID*	As per ETSI 103197 DVB Simulcrypt. Hexadecimal format.	From 0 to 4294967295
CA descriptor location*	The location in the PMT for the CA descriptor that describes the ECM streams	Dropdown menu: Service, Component

These settings are only for advanced configurations. Default values should be suitable for the majority of use cases.

Parameter name	Description	Possible values
EIS ECM ID To PID Mappings	Comma-separated list of ECM IDs to PIDs. The ID is the field position unless specified. Example: 200,201,3:400,5-10:500 would map ID->PID: 0->200, 1->201, 3->400, [5,10]->500	String of max 32 characters

Parameter name	Description	Possible values

Client ID*	As per ETSI 103197 DVB Simulcrypt. Hexadecimal format.	From 0 to 4294967295
Automatic	Will accept the first connection request from the EMMG regardless of Channel or Stream ID	Tick box, checked by default.
Input Bitrate Limit*	Limit to the incoming bitrate (only present when Automatic is not checked)	From 1 to 4294967295

If the Automatic tickbox is unchecked the following table will appear, which will allow to add and remove EMMG streams configurations.

For each EMM stream the following parameters are available:

Input Bitrate Limit	Limit to the incoming bitrate	From 1 to 4294967295

These settings are only for advanced configurations. Default values should be suitable for the majority of use cases.
