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. 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 from a database. A first mitigation strategy causing filters to filter an IPTV signal according to a frequency range associated with the amplitude modulation broadcasting facility to limit a first interference on the IPTV signal provided to the first geographical location when the first distance is less than the first threshold distance is determined.
