Table 4.75: Bandwidth Options
Selected Option
Description
6 MHz
Terrestrial transmitter channel spacing is 6 MHz.
7 MHz
Terrestrial transmitter channel spacing is 7 MHz.
8 MHz
Terrestrial transmitter channel spacing is 8 MHz.
10 MHz
Terrestrial transmitter channel spacing is 10 MHz.
12 MHz
Terrestrial transmitter channel spacing is 12 MHz.
Modulation Type Option
To access the Modulation Type option, press the Modulation Type softkey
in the Delivery Descriptor Menu. This enables the type of modulation
used to be specified.
Table 4.76: Modulation Type Options
Selected Option
Description
QPSK
Terrestrial transmitter uses QPSK modulation.
16-QAM
Terrestrial transmitter uses 16QAM modulation.
64-QAM
Terrestrial transmitter uses 64QAM modulation.
Hierarchy Option
To access the Hierarchy option, press the Hierarchy softkey in the
Delivery Descriptor
Menu. This screen enables the hierarchy of the
terrestrial transmission to be specified.
Table 4.77: Hierarchy Options
Selected Option
Description
Non-Hierarchical
Terrestrial transmission is not hierarchical.
Alpha=1
Terrestrial transmission is hierarchical, and the
a value = 1.
Alpha=2
Terrestrial transmission is hierarchical, and the
a value = 2.
Alpha=4
Terrestrial transmission is hierarchical, and the
a value = 4.
FEC (HP) and FEC (LP) Options
To access the FEC (HP) or the FEC (LP) option, press the FEC (HP) or
FEC (LP) softkey in the Delivery Descriptor Menu. These screens
enable the inner FEC schemes used by the terrestrial transmitter to be
specified.
NOTE…
If the Hierarchy option is set to Non-Hierarchical, then only the FEC Rate parameter is used and
shown on the display.
