摘要
An embodiment of a method includes determining a channel signature for each of a plurality of cable devices associated with a selected household; determining whether at least one of the channel signatures is substantially different than the remaining ones of the channel signatures; and if at least one of the channel signatures is substantially different than the remaining ones of the channel signatures, flagging the selected household for potential theft of services review. Additional embodiments may include determining a radio frequency (“RF”) signal power level for each of the cable devices; calculating a sum of the determined RF signal power levels; determining whether the calculated sum is equal to an RF power signal level measured at a tap of the selected household; and if the calculated sum is not equal to the measured RF power signal level, flagging the selected household for potential theft of services review.
