Patent ID: 8077706

Claim:
A method of controlling a signal processing system comprising: receiving channel signals at a local collection facility; encoding the channel signals into IP signals; communicating IP signals from the local collection facility to a remote facility; multiplexing IP signals to form a multiplexed signal at a primary multiplexer at the local collection facility; multiplexing IP signals to form the multiplexed signal at a backup multiplexer at the local collection facility; forming a transport stream signal by encrypting the multiplexed signal at a primary transport processing system; forming the transport stream signal by encrypting the multiplexed signal at a backup transport processing system; modulating the transport stream signal to form a modulated signal at a primary modulator; modulating the transport stream signal to form the modulated signal at a backup primary modulator; forming a first output signal from the modulated signal; and forming an output signal using at least one of the primary multiplexer, the primary transport processing system, and the primary modulator and at least one of the backup multiplexer, the backup transport processing system and the backup modulator.
