Abstract
A system and method suitable for processing television signals includes a remote facility and a local collection facility in communication with the remote facility. The local facility has a plurality of receivers receiving a plurality of channel signals and a plurality of encoders generating a plurality of encoded signals from the plurality of channel signals. The local collection facility includes a primary multiplexer multiplexing the plurality of encoded signals to form a first multiplexed signal and communicates the first multiplexed signal to the remote facility. A monitoring system at a remote facility commanding switching to a back-up multiplexer at the local collection facility. The back-up multiplexer multiplexing the plurality of encoded signals to form a second multiplexed signal and communicating the second multiplexed signal to the remote facility. The remote facility generating an output signal in response to the second multiplexed signal.
