Description
Configuration of the processing mode:
Configuration of the Ethernet interface (IP-data) for modulator,
demodulator or modem. It offers an Ethernet interface for a modulator,
demodulator or modem to transmit or receive IP packets (or Ethernet
frames) over satellite. The different options are:
•
Eth(IP) <-> Air(TS), applicable for DVB-S and DVB-S2: : dataflow
from an ethernet input to the modulator board. Ethernet input is
encapsulated in TS packets, then put in Baseband Frames and
forwarded towards the modulator board and received from the
demodulator board.
•
Eth(IP) <-> Air(XPE), applicable for DVB-S2.2.
dataflow from an
ethernet input to the modulator board. DVB-S2 Baseband
Frames are generated towards the modulator board and
received from the demodulator board.
•
Eth(IP) ↔ Air(GSE) applicable for DVB-S2.
IP data is encapsulated in GSE and carried directly in DVB-S2 Base
Band Frames. GSE encapsulation/decapsulation is performed in the
modulator/demodulator.
