ABSTRACT:
DVB-S/S2 transmodulator for VSAT units employing IP based communication. The transmodulator is optimized for VSAT networks, enabling legacy VSAT units to benefit from the developments of the advanced DVB-S2 standard. The transmodulator appears transparent to the legacy VSAT unit that is configured to operate with the older DVB-S standard. Some embodiments offer a unique feedback channel allowing the transmodulator to send messages and information to the ground station via the VSAT itself.
