Method and system for monitoring and switching between a first uplink signal processing circuit and a secondary uplink signal processing circuit

A method for broadcasting television signals using a ground segment system comprising:

• generating a primary multiplexer signal at a primary multiplexer, said primary multiplexer signal comprising a first plurality of television signals;
• generating a primary transport processor signal at a primary transport processor from the primary multiplexer signal;
• generating a primary modulator signal at a primary modulator from the primary transport processor signal;
• generating a secondary multiplexer signal at a secondary multiplexer, said secondary multiplexer signal comprising a second plurality of television signals;
• generating a secondary transport processor signal at a secondary transport processor from the secondary multiplexer signal;
• generating a secondary modulator signal at a secondary modulator from the secondary transport processor signal;
• coupling the primary modulator signal and the secondary modulator signal to a switch;
• communicating at least one of the primary multiplexer signal, the primary transport processor signal and the primary modulator signal and at least one of at least one of the secondary multiplexer signal, the secondary transport processor signal and the secondary modulator signal to a monitoring-and-control circuit
• generating, by the monitoring-and-control module, a display comprising at least one of the primary multiplexer signal, the primary transport processor signal and the primary modulator signal and at least one of at least one of the secondary multiplexer signal, the secondary transport processor signal and the secondary modulator signal;
• monitoring, at the monitoring-and-control module, at least one of the primary multiplexer, the primary transport processor, and the primary modulator to determine if one of the primary multiplexer signal, the primary transport processor signal, and the primary modulator signal has been corrupted;
• controlling the switch to form an output signal corresponding to either the primary modulator signal or the secondary modulator signal in response to monitoring;
• and
• broadcasting the output signal to a plurality of user devices.

A system for broadcasting television signals using a ground segment comprising:

• an uplink signal processing system comprising a primary uplink signal processing circuit generating a primary output signal from a first input television signal and a secondary uplink signal processing circuit generating a secondary output signal from the first input television signal;
• a switch receiving the primary output signal and the secondary output signal;
• a monitoring and control system monitoring the primary output signal and the secondary output signal, generating a monitoring signal by monitoring at least one component of the primary uplink signal processing circuit and the secondary uplink signal processing circuit determining whether the at least one component has been corrupted and controlling the switch to form a switch output signal corresponding to the secondary output signal in response to the monitoring signal;
• and
• a broadcasting circuit for broadcasting the switch output signal to a plurality of user devices.
