| 1. A transmodulator for a Very Small Aperture Terminal (VSAT) employing Internet Protocol (IP) based communication, said transmodulator
comprising:
a processing unit;
a legacy format modulator;
a DVB-S2 demodulator;
wherein said processing unit is coupled to said legacy format modulator and to said DVB-S2 demodulator, and wherein said legacy
format modulator is coupled to the VSAT circuitry and said DVB-S2 demodulator is coupled to the VSAT unit's Low Noise Block
(LNB); and wherein said DVB-S2 demodulator is configured to demodulate DVB-S2 signal arriving from said LNB and deliver it
to said processing unit and wherein said legacy format modulator is configured to modulate signal coming from said processing
unit into a legacy format signal and deliver it to the VSAT circuitry,
wherein said transmodulator is coupled to the VSAT in a fixed parameters configuration, wherein said parameters include at
least one of: carrying signal frequency, symbol rate, code rate, output power,
and wherein the fixed parameters are configured such that the configuration enables the transmodulator to remain operable
upon parameters change of a service provider in operative association with the VSAT.
