To support the reception of multicast media streams, broadcast from SatstreamNet
when operating in independent mode ie via separate satellite channels, independent
of any on-board broadband network, each vessel will be equipped with Satstream Media’s
Satellite Receiver Equipment. An independent mode configuration showing the Receiver
Equipment and Media Gateway is shown in the figure opposite.
The Receiver Equipment supports the movement of the vessel from one satellite beam
to the next by automatically re-configuring the additional satellite modem with
the appropriate parameters of the new satellite beam such as satellite channel frequency,
data rate and modulation coding scheme using pre-stored satellite beam maps and
signal parameters as well as real time inputs such as vessel GPS and modem feedback
signals.
The equipment set includes the following
- a satellite modem to receive the separate satellite channels
- our proprietary roaming controller which configures the satellite modem receive
parameters;
- optional DVB-IP Receiver to receive specific encrypted TV channels
