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).

Characteristics of HUB Network:

• Up to 150 Mb/s downstream and up to 25 Mb/s upstream
• Downstream interface is MPEG/DVB-S (Moving Picture Expert Group/DVB-Satellite)
• Upstream interface is DVB-RCS
• Optimized for IP (Internet Protocol) and multi-media contenting Remotes or Satellite Interactive Terminals (SIT)
• Open standard design (DVB-RCS) Broadband & Multimedia
• Qualified with multiple IP/DVB broadcast platform vendors
• The System is designed to support up to 80,000 SIT
•  unitsEvery Remote Terminal is able to support many PC or IPTV in LAN, depending on used bandwidth
• DVB-S can be upgraded by the most effective and cost less 2nd generation DVB-S2 CCM and 3rd generation DVB-S2 ACM platform, forward and reverse compatible

DVB-RCS Service and Applications:

• Broadband Service Provider Platforms (SPP) for Urban, Rural, Remote and Mobile Applications of Multimedia IPTV & ISP
• Enterprises and Private Networks (EPN) Broadcasting and Content Distribution (BCD) of IPTV
• Satellite News Gathering (SNG)
• Satellite Emergency and Security Management (SESM)
• Global Satellite Augmentation System (GSAS)
• Defense Information Management (DIM)
