CLAIMS
1. Multi-protocol Satellite User Terminal able to support one-way/two-way connectivity in a topology of meshed networks which utilizes the SKYPLEX technology on satellite.
2. Multi-protocol Satellite User Terminal of claim 1 which guarantees the conformity to the "native" synchronization of the SKYPLEX unit.
3. Multi-protocol Satellite User Terminal according to claims 1 or 2 wherein the transmission on satellite channel is in accordance to: (i) single-channel-per-carrier (SCPC) mode, (ii) time-division-multiple-access (TDMA) mode; (iii) other access modes (for example MF-TDMA) which can be supported after specific requests by the user .
4. Multi-protocol Satellite User Terminal according anyone of previous claims wherein a driver of the satellite modem board to be inserted into a slot of the terminal itself supports the transmission with Reed-Solomon (DVB-S compatible) or Turbo (DVB-RCS compatible) coding.
5. Multi-protocol Satellite User Terminal of claim 1 or 2 able to support one-way and two-way IP connectivity in the following cases:
• Satellite networks in accordance to the standard for coding DVB-S channel with transparent transponders;
• Satellite networks making use of SKYPLEX radio interface on the return channel.
6. Multi-protocol Satellite User Terminal according to claims 1 to 3 having an apparatus control and a management comprising:
• a manual operating mode through a local/remote man-machine interface for operator based upon Web;
• a control and monitoring remote interface based upon SNMP V2 protocol able to support the trap generation towards a centralized Network Management System (NMS);
• a both local and remote interface for manual intervention of an operator by means of a prompt in a Linux shell;
• a remote interface based upon the Connection Control Protocol (CCP) protocol for supporting an operating mode controlled by the Network Control System (NCS) included in the SkyplexNet Network Operation Centre (NOC); it intervenes thanks to the support in the terminal of a NCS Agent able to support connections both Activated by NOC and

Activated by the Terminal itself (with negotiation/management of the Service Quality and resource management);

^

• a remote interface for the dynamic management of the Service Information of DVB- S/MPEG-TS by means of the protocol towards the SIMS server (managed by the Eutelsat satellite operator) able to register/enable entire intervals of logical resources such as PlDs, SIDs, Programme, Service and Provider names in the transmission Transport Stream from the terminal itself;
• a remote interface for supporting a protocol of Medium Access Control (MAC) layer for the dynamic management of outband capability requests.
7. Multi-protocol Satellite User Terminal according to claims 1 to 5, wherein a FPGA remote updating of the satellite modem board is supported in order to guarantee to maintain and to enable additional options and functions for accessing the physical channel.
8. Multi-protocol satellite User Terminal according to claims 1 to 7, wherein the apparatus itself can be updated remotely at the different inner kernel, firmware, database levels in order to guarantee to maintain and to enable additional options and functionalities upon request.

9. Multi-protocol satellite User Terminal according to claims 1 to 5, wherein the reception and the search for television services can be optionally enabled starting from the decoding of PES

Audio /Video packages natives of MPEG-TS.
10. Multi-protocol satellite User Terminal according to claims 1 to 5, wherein a functionality of Operation and Maintenance for supporting the monitoring, configuration and base control of the terminal unit via satellite can be optionally enabled.
11. Multi-protocol satellite User Terminal according to claims 1 to 8, having a related modular architecture composed by:
• a driver of SATPHY satellite modem for (i) accessing the services of the SATPHY board for accessing the channel setup, (ii) managing the transport stream cell (TSC) sequences to be sent to the modem section, (iii) performing the channel acquisition, (iv) properly formatting the burst sequences of TSC cells;
• a de-multiplexing driver of MPEG-TS cells;
• a DVB/IP receiving router with de-multiplexing function of Multi Protocol Encapsulation (MPE) sections;
• a software module of Return Channel System for (i) encapsulating IP packages in the MPEG-TS format based upon the MPE standard, (ii) implementing the client of SIMS protocol for the dynamic management of Service Information, (iii) managing the channel synchronization procedures, the steady state keeping with the support of the protocol of SKYPLEX "native" synchronization and of schemes at Superframe level, (iv) implementing the client of CCP protocol of layer three for exchanging and managing the signalling with the central System NCS, (v) performing the MAC scheduling, (vi) extracting from the MPEG-TS demux the signalling private sections, (vii) performing the advanced functionalities of IP interworking with respect to the layers of higher level, (viii) supporting the terminal Monitoring and controlling main interface by means of a SNMP sub-agent.
