Abstract
Multiple systems for delivering satellite video signals are disclosed. An embodiment of the present invention comprises a module comprising a multiswitch, the multiswitch selectively directing the satellite video signals to a plurality of outputs of the multiswitch, an interface for delivering the satellite video signals to at least one receiver, and a power inserter, coupled between the interface and the at least one receiver, for controlling the flow of signals between the multiswitch and the at least one receiver, wherein the power inserter continuously flows the satellite video signals to the at least one receiver while selectively flowing commands between the module and the at least one receiver.
Claims20
A system for delivering satellite video signals for display on a monitor, comprising:
- a module comprising a multiswitch, the multiswitch selectively directing the satellite video signals to a plurality of outputs of the multiswitch;
- an interface for delivering the satellite video signals to at least one receiver;
- and
- a power inserter, coupled between the interface and the at least one receiver, for controlling the flow of signals between the multiswitch and the at least one receiver, wherein the power inserter continuously flows the satellite video signals to the at least one receiver while selectively flowing commands between the module and the at least one receiver.
A system for selectively delivering satellite video signals received from a plurality of satellites to at least one receiver, comprising:
- a multiswitch, for selectively directing the satellite video signals based on which satellite of the plurality of satellites broadcast the satellite video signal to an output of the multiswitch;
- at least one tuner, coupled to the output of the multiswitch, for tuning to a specific portion of the satellite video signal, the specific portion of the satellite signal selected based on a command received from the receiver;
- at least one demodulator, coupled to the at least one tuner in a respective fashion, for demodulating the specific portion of the signal into a plurality of demodulated signals;
- an interface for delivering the plurality of demodulated signals to the receiver, wherein the plurality of demodulated signals are combined into a single combined signal and delivered to the receiver on a single output of the interface;
- and
- a power inserter, coupled between the interface and the at least one receiver, for controlling the flow of signals between the multiswitch and the at least one receiver, wherein the power inserter continuously flows the plurality of demodulated signals to the at least one receiver while selectively flowing commands between the module and the at least one receiver.
