Abstract

A system and method for switching to a back-up encoder includes a first encoder processing a first channel signal to form a first encoded signal, a second encoder an uplink signal processing system generating a first uplink signal from the first encoded signal. A monitoring system previews the first channel signal encoded through the second encoder while the uplink signal processing system generates the first broadcast signal using the first channel signal encoded through the first encoder. The monitoring system redirects the first channel signal through the second encoder to form a second encoded signal. The uplink signal processing system generates a second broadcast signal with the first channel signal through the second encoder.
