If enabled, 1 TPS bit (s48) is used to signal that at least one data stream with time slic-
ing exists in the multiplex.
For hierarchical coding, the information for the HP path is transmitted in OFDM frames
1 and 3. The information for the LP path is transmitted in OFDM frames 2 and 4. See
Table 4-7 .
For non-hierarchical coding, no distinction is made between the OFDM frames.

MPE FEC
Requires "Coding > DVB-H > On".
Enables/disables MPE FEC .
If enabled, 1 TPS bit (s49) is used to signal that MPE FEC is used in at least one data
stream.
For hierarchical coding, the information for the HP path is transmitted in OFDM frames
1 and 3. The information for the LP path is transmitted in OFDM frames 2 and 4. See
Table 4-8 .
For non-hierarchical coding, no distinction is made between the OFDM frames.
