Abstract

A method is disclosed for determining a mitigation strategy to limit a potential source of interference on an Internet Protocol television (IPTV) system. A new user installation request is received at a server in the IPTV system. A first geographical location of a customer premises associated with the new user installation request is received. A second geographical location of an amplitude modulation broadcasting facility is received. The first geographical location and the second geographical location are plotted. A first distance between the first geographical location and the second geographical location is determined. A first signal transmission power rating for the amplitude modulation broadcasting facility is retrieved. A first mitigation strategy to limit a first interference of the amplitude modulation broadcasting facility on an IPTV signal provided to the first geographical location when the first distance is less than the first threshold distance is determined.
