EXPLANATION OF THE SEARCH MODES

In the various menu pages you can make a selection from various search modes. The search
mode gives the possibility to scan a satellite or transponder in a particular manner. The
search modes are identified as:
All In this mode the built-in database is used to select the available transponders.
The digital and analog channels that belong to these transponders are
searched for and added to the all channel list.
FTA In this mode the built-in database is used to only search for the available
FTA channels which are then added to the all channel list. In the real world it
seems that the service providers do not always accurately code their channels
with a scrambled or FTA code. For this reason you may find that some
searched channels are scrambled. Also there is a possibility that scrambled
channels are coded as FTA. These channels will then be missed out because
of the erroneous code.
Network In this mode the built-in database or information from the received stream is
used to search for the transponders that are included with the currently
received network. The digital channels that belong to this network are
searched for and added to the all channel list.
TP In this mode the built-in database or information from the received stream is
used to search for or scan in the selected transponder. The digital and/or
analog channels that belong to this transponder only are searched for or
scanned in and added to the all channel list.
Digital In this mode the built-in database is used to search for the available digital
channels. The digital channels are then added to the all channel list. The digital
channels are shown as white channel names for easy recognition.
Analog In this mode the built-in database is used to add the analog channels to the all
channel list. The analog channels are shown as black channel names for easy
recognition.
Digital IF In this mode the currently received satellite is scanned for digital channels. The
digital channels, within the tuner bandwidth and selected symbol rates are
scanned in and added to the all channel list.
Analog IF In this mode the currently received satellite is scanned for analog channels.
The analog channels within the tuner bandwidth are scanned in and added to
the all channel list.
Update In this mode the built-in database is used to search for the available digital
channels. Then all new channels are added to the all channel list.
None Transponders on the selected satellite are not searched for.

A card that contains a 'smart' code and is used to de-scramble
encrypted broadcasts when placed in a decoder or receiver
with a built-in decoder.
A satellite master antenna TV system is a system which
shares the reception resources and is intended for the
distribution of TV and radio signals to the user in one ore more
buildings.
The signal which is received from the transponder which
contains the together with the video signal, additional
information that the receiver needs in order to process the
received signal correctly.
Invisible information which tells the receiver at which speed
(rate) the transponder sends the digital information (symbols).
The receiver must be able to handle the symbol rate to
process the signal correctly into a correct image.
Equipment inside a satellite responsible for receiving a single
uplinked channel and rebroadcasting it back to Earth.
In the satellite industry, vertical is used to indicate the direction
in which the received signal is polarized. Normally you will find
that it is abbreviated as V.
