Abstract:
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.
