Description
Configuration of the data field length mode. When operating with non-
baseband frame input formats (i.e. a MPEG transport stream input or
generic input streams) the raw input stream is encapsulated into DVB-S2
baseband frames. The payload size of these frames is referred to as data
field length and the maximum possible data field length is determined by
the selected frame type and modcod.
Two data field length encapsulation modes are defined:
•
Automatic
: Upon selection of frame type and/or modcod, the data
field length size is automatically set to the corresponding maximum
payload size and the sync distance is set to 0.
•
Manual
: Upon selection of frame type and/or modcod, the data field
length size remains at the previous value of the baseband data field
length (
MoDFL
) variable as long as this value is supported by the
new frame type and modcod. In case the baseband data field length
(
MoDFL
) variable exceeds the maximum payload size, the data field
length value will be clipped to the maximum. Also the sync distance
value will be kept or clipped.
