-DVB-T2 is a second generation modulation standard for terrestrial broadcasting used by countries
that adopted DVB standards.
-ISDB-T is a modulation standard for terrestrial broadcasting used by countries that adopted
Japanese standards.
-QAM B is a modulation standard for cable TV used mostly in North America. This is also known as
J.83 Annex B.
-QAM C is a modulation standard for cable TV used mostly in Asia. This is also known as J.83
Annex C.
-IQ is a playback mode playing out Inphase and Quadrature phase of the modulated components.
-T2-MI is a modulation standard that defines the communication protocol used between the T2
gateway and the DVB-T2 modulator to carry synchronization information for SFN broadcasting,
signalling information to control modulators transmission and data that is encapsulated within DVB-
T2 Baseband frames.
-DVB-S is a modulation standard for satellite broadcasting.
-DVB-S2 is a second generation modulation standard for satellite broadcasting.
NOTE: Most of the formats are optional components of DekTec hardware and not available for
every hardware device. Please verify that your DekTec hardware device is capable and licensed for
that mode (See DtInfo). If the DekTec device is not licensed, the option will not show up in the list of
modulation standards.
3.5.1 General RF settings
When playing a stream via an RF adapter, the user has to set different parameters that depend on
the type of modulation. Each modulating standard has different parameters and settings and
different bandwidth.
3.5.1.1 RF Channel frequency setting
Most DekTec modulator devices are fully agile across the UHF/VHF band or the Lband.
The user has to select which part of the RF spectrum to send the modulated signal. Enter the channel
to enter the center frequency of the digital modulated signal.
