Click the Streams tab and
enter output PID for the ECM

Leave the Bit rate (k) set to
30 kbps
ECMs usually take 14 kbps but 30 kbps
allows for any overhead
If scrambling is at service level, give each
service a different SCG ID unless the
customer specifies otherwise.
If scrambling is at component level, give each
component a different SCG ID unless the
customer specifies otherwise.

Set the SCG ID (Scrambling
Control Group ID)
This defines
whether a
service or
component is
scrambled
with the
same control
word or with
a different
control word
See Section
D.9, Use of
the
Scrambling
Control
Group ID for
more
information
If several services or components need to be
scrambled with the same control word (i.e.
with the same ECM), then enter the same
SCG in the ECM parameters. It is also
essential that all the ECM settings are exactly
the same.
