Network Topology

Over The Top Functionality

In this example, the SatstreamNet Hub interfaces at the IP level to the existing broadband network at the teleport utilised by the VSAT Broadband network service.
The vessel GPS is extended to the OTT Media Gateway and the OTT Media Gateway monitors the vessel location on a regular basis.
The OTT Media Gateway has the ability to disable the reception of live media streams when the vessel enters national waters. This is a unique feature of SatstreamNet and makes SatstreamNet the first true Media@Sea network.
On board the vessel, the media network is added seamlessly into the existing VSAT broadband network, operating on a separate Virtual LAN (VLAN) so that there is no interference with existing operational communications services. As with the Independent mode, the OTT configuration benefits from the same software development roadmap to add additional features to the service.

Independent Mode Functionality

In this simple example, the SatstreamNet Hub uses a separate satellite teleport to that used by the VSAT Broadband network service. It could also, of course, operate via the same teleport.
As SatstreamNet only uses an outbound/downstream satellite channel, it does not interfere with the operational communications network on board the ship. As such, multicast content can be received on the same VSAT antenna used by the operational network.
If a vessel operator has an operational communications service provider that does not provide them with media services, then one of our service partners can arrange this without having to replace any of the existing VSAT equipment.
On board the vessel, the media network is added seamlessly into the existing VSAT L-Band receive chain by the addition of a signal splitter. There is negligible impact to the operational network as a result of adding the splitter to the Rx chain.
Ethernet cable can support a separation between the Roaming Controller and the Media Gateway of around 100 metres. Longer distances are achievable by simply adding an Ethernet Extender or Ethernet switch in the link to boost the signal.
