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, and so on. The
receiver reverts to the previous set of tuning
settings/information and channels until these
changes are either saved or abandoned.
Basic - Requires NIT to be
present.
Auto - Uses all the
available service list tables
and it will acquire if any
table is present.
Custom - Uses the Custom
Tuning parameters,
specified by the user.
The default is Basic.
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,
any 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.
Select Sets the method used by the RF tuner to
determine which input to use when switching
transports.
UserCfg - User
configuration will only use
the active RF input.
SW Map - Software map
uses the orbital position
settings from each input
and map it to those in the
NIT.
