Abstract:
A system and method for switching between receiver and decoder circuits includes a first receiver receiving a first channel signal and forming a first channel signal, a second receiver receiving the first channel signal and forming a second channel signal and a monitoring system monitoring the first channel signal and the second channel signal and generating a monitoring signal. The system also includes a transfer switch in communication with the first channel signal and the second channel signal. The monitoring system controls the switching of the transfer switch from the first signal to the second signal in response to the monitoring signal. The transfer switch forms a switch output signal.
