DVB-H only features are enabled and available through the menu system when
the TPS length indicator is set to 33 bits. Otherwise, DVB-T is used as marked by the
TPS length indicator being 31 bits. The two extra bits in DVB-H flag the use of time
slicing and MPE-FEC (see below). Options are:
DVB-T (31 TPS bits) DVB-T mode with a TPS length indicator of 31 bits.
DVB-H (33 TPS bits) DVB-H mode with a TPS length indicator of 33 bits.
MPE-FEC

Correction (MPE-FEC) used on top of the DVB-T channel coding. The available options
are:

HP The HP TS uses MPE-FEC.
LP The LP TS uses MPE-FEC.
HP&LP Both the HP and LP TS use MPE-FEC.

slicing:
OFF Time slicing is not used

LP At least one elementary stream within the LP TS uses time slicing.
