Menu Item Description Parameters
Tune Mode Select which tables are required for the service
list creation and signal acquisition.
Note: When editing the tuning, the device is in
a transient state while acquiring tuning
information and channel lists, etc. The receiver

settings/information and channels until these
changes are either saved or abandoned.
Basic - Requires NIT to be
present.
Auto - Uses all the service
list tables and it will
acquire if any service list
tables are present.

Tuning parameters,
specified by the user.

CA Ctl Sets how the conditional access will attempt to
descramble the scrambled programs. The
behavior of this setting is different between
PowerVu streams and those that require a
CAM.
For PowerVu streams:
Std - In standard mode, if
a program is not
authorized, even if some
services are not scrambled,
the whole program will
not be authorized.
Open - In open mode, if a
program is not authorized,
services in the program
that are not scrambled will
still be available.
For Non-PowerVu (CAM)
streams:
Std - In standard mode, if
a program’s CA system is
not supported by the
CAM, the channel is not
authorized.
Open - In open mode, all
the program’s CA systems
are validated by the CAM.
The channel is always
authorized.

MPEG over IP stream, for each data port, to
use as a transport input.
UserCfg - User can select
one of the available MPEG
over IP streams for Data1
and/or Data2 ports.
SW Map - Pre-defined
software algorithm is used
to determine the MPEG
over IP stream for Data1
and Data 2 ports.
