Patent ID: 8804499

Claim:
A method for broadcasting television signals using a ground segment system comprising: communicating a first group of television signals comprising a plurality of single program transport stream (SPTS) signals to a primary signal processing circuit and a secondary signal processing circuit; generating a primary modulated multiplexed transport output signal for the first group of television signals at the primary signal processing circuit; generating a secondary modulated multiplexed transport output signal for the first group of television signals at the secondary signal processing circuit; coupling the primary modulated multiplexed transport output signal and the secondary modulated multiplexed transport output signal to a switch having a switch output signal; communicating signals from at least one component of the primary signal processing circuit and at least one component of the secondary signal processing circuit to a monitoring-and-control module; generating, by the monitoring-and-control module, a display comprising the primary modulated multiplexed transport output signal and the secondary modulated multiplexed transport output signal; monitoring, at the monitoring-and-control module, at least one component of the primary signal processing circuit and the secondary signal processing circuit by determining whether the at least one of the components of the primary signal processing circuit has been corrupted and generating a monitoring signal when at least one of the components of the primary signal processing circuit has been corrupted; switching, using the monitoring-and-control module, the switch output signal from the primary modulated multiplexed transport output signal to the secondary modulated multiplexed transport output signal in response to the monitoring signal; and broadcasting the switch output signal to a plurality of user devices.
