Abstract
An RF multiple switching apparatus, such as one included in or coupled to a broadcast satellite signal receiver, having a plurality of multiple RF signal input ports for receiving respective ones of a plurality of RF signals, such as broadcast satellite television signals, utilizes a relative signal strength indicator, such as an automatic gain control signal, to determine the difference between the actual input signal that is present at one of the plurality of signal input ports and a false signal that appears to be present at another signal input port of the plurality of signal input ports due to the RF signal bleeding between the multiple signal input ports. During a setup configuration determination or routine, the switching apparatus steps through each RF signal input, extracts pertinent transmission network (such as a satellite transmission network) information, determines a relative signal strength indicator for the RF signal, and compares the obtained information. Setup data for each RF signal input is stored according to the comparison.
