Abstract
A method and apparatus for detecting leakage of a digital CATV channel signal from a CATV system. The digital CATV channel signal is amplitude modulated with a tag signal having a frequency in the range of about 3 Hz to about 35 Hz, and coupled to the CATV system. At a point of leakage from the CATV system, the amplitude modulated digital CATV channel signal can be detected using a leakage detector capable of recovering the tag signal.
