<p>A system and method for detecting ingress on shared media is presented. In one embodiment, among others, an input signal is selectively attenuated at each source site using a pseudo-random pattern, thereby amplitude modulating at low level the signal in a pseudo-random manner. Each encoded signal from each of the source sites is combined on shared media connected to a headend. The headend receives a composite signal comprising all of the individual source site signals and extracts the source site information using the pseudo-random pattern, thereby determining which of the source sites is the source of ingress.</p> |
