D.9.3 SCG ID in nCompass Control
In nCC, the SCG ID is specified when defining the ECM.
Notes: When creating a new ECM, the default value for the SCG ID is 1. It is up to
the user to select a correct value. If users are not aware of the meaning of
the SCG ID, they usually accept this value, sometimes causing invalid
configurations. See Section D.9.4 on guidelines on selecting SCG ID
values.
nCC will allow different SCG IDs to be specified for service and component
level ECMs, but such a configuration will fail validation when activated. This
is fixed in version 4.5 and above.

IDs:

D.9.5 Shared ECMs
The critiera for creating a shared ECM are:
• The ECM must be routed on the same mux, i.e. the ECMs must be in the same
transport stream.
• The ECM must be on the same ECM Generator.
