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.

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.
If the Hierarchy option is set to Alpha=n, then the FEC (HP) and
FEC (LP) parameters provide two levels of modulation. Transmission
starts with the code rate for the HP level of modulation and ends with the
code rate for the LP level.
