ECMG Parameters
The following table describes the ECMG parameters.
Parameter Description
ECMG Name ECMG name (max 20 characters) acts as a label to facilitate the identification of
the ECMG in the CA system.
ECMG Type

Standard: DVB Simulcrypt.

M_Crypt: (DVB Simulcrypt) allows empty ECMs to reset scrambling.

Nagra: (DVB Simulcrypt) prefetch less ECMs in advance to enable quicker
use of updated AC.
CA System ID (Hex) Used to indicate the type of CA system applicable for the associated ECM
stream. Contact your CA vendor for more information. CA System identifier is
defined in table 3 CA_system_ID of ETR 162.
CA Sub System ID
(Hex) Used to differentiate multiple ECMGs from the same CA vendor in the CA
application. Contact your CA vendor for more information.
ECMG PID Source Select the desired ECM PID source.

ECM ID: SCG Provisioning message is used to determine the ECM PID.

Auto: The multiplexer of the RFGW-1 chooses the ECM PID from the list of
free PIDs.
Note: The list of free PIDs, determined by the multiplexer can be limited by
defining limits (ECM PID Lower Limit, and ECM PID Upper Limit).
ECMG PID Lower
Limit (Hex) Lower limit for ECMG PID.
ECMG PID Upper
Limit (Hex) Upper limit for ECMG PID.
ECMG
Streams/ECMG Number of ECMG streams required.
Open ECMG
Streams/ECMG Number of open ECMG streams to the ECMG of the CA system.
Automatic Channel ID
Selection Enable/disable automatic channel ID selection.
Enable Hot Backup Not supported at this time (future use).
