Return Channel Satellite Terminal using Personal Computer for DVB-RCS and satellite communication system

摘要

PURPOSE: A PC-based satellite communication terminal and a satellite communication system using the same are provided to offer a multimedia Internet service by a satellite communication through a PC. CONSTITUTION: A forward link receiving unit(100) demodulates, decodes, and PID(Packet ID)-filters a signal received through a satellite antenna(61). A data processing unit(300) processes a forward link signaling message, a control message, and SNMP(Simple Network Management Protocol) IP(Internet Protocol) packets, which are outputted from the forward link receiving unit(100). An Ethernet interface(400) interfaces data between the data processing unit(300) and a PC(90). A TDMA(Time Division Multiple Access) transmitting and receiving unit(200) converts IP traffic data from the PC(90) and a message outputted from the data processing unit(300) into signals capable of being transmitted to a satellite.
