Summary of DVB-S2 ACM Savings: DVB-RCS Indoor and Outdoor Units Satellite DVB-RCS Outdoors Unit  (ODU) or Transceiver Antenna:  which can be installed on the tracking antennas, SIT equipment The ODU is transceiver antenna,roof or mast and may provide to Satellite Interactive Terminal(SIT) or Indoor Unit (IDU) the following features: - Full DVB-RCS compliance and very easy to install with RF Range of C, Ku or Ka-band antenna sizes of 0.75 - 2.4 m. - Standard ODU/IDU interfaces ensure full compatibility with any DVB-RCS or VSAT modem. - Two-way enhanced DiSeqC control capability, which provideInterface between IDU and transmitter supporting automatic line-up function at installation.Using special Mobile satellite can be installed as Mobile Interactive Terminals (MIT) on boardMobiles, such as ships, land road and rail vehicles (cars, trucks, busses and trains) and airplanes. Satellite DVB-RCS Indoor Unit (IDU)  or Satellite Transceiver : This unit can connect

Main Components of the HUB

Main Components of the HUB: Network Control Centre (NCC)  interfaces Operator and HUB for billings assuring traffic management, supervision,  protocol handling and bandwidth management. Forward Link Subsystem (FLS) provides the encapsulation of IP transfer of data packets into adequate MPEG frames,or according to the DVB-S MPEG multiplexer and modulat transmitting specification. Return Link Subsystem (RLS) collects the Turbo-coded MF-TDMA bursts transmitted by all the terminals in the network. Each one of RLS receivers can be individually configured to operate at any frequency, bit-rate or coding rate. The modular design of the RLS enables the system to scale from small to very large networks. Reference and Synchronization Subsystem (RSS) delivers the synchronization and timing information in the gateway for synchronization of the entire satellite network. Remotes or SIT units consist of two main transceiver units, the Indoor Unit (IDU) and the Outdoor Unit (ODU).

DVB-RCS - CNS Systems: (DVB-RCS) :Special Benefits of Digital Video Broadcasting-Return Channel via Satellite The DVB-RCS is the best tool to be implemented in urban, rural and remote areas and to be provided backbone to terrestrial telecommunication and GSM or cellular networks for complete communication coverage in one Country. To provide modern IPTV and Voice, Data and Video over IP (VDVoIP) via Satellite Broadcast, Broadband, Multimedia and fast Internet is necessary to include Space Segment, Hub as Ground Earth Station (GES) and Interactive Satellite Terminals (IST) and Mobile Satellite Terminals (MST) or simply Remotes known as Very Small Aperture Terminals (VSAT).
