Abstract:
A method of tagging signals for leakage detection and measurement in cable television networks which uses additional signals carrying the tagging information and transmitted in these networks. A narrowband tagging signal or signals are placed in the unused frequency spectrum parts of any used cable television channel, in particular in the guard bands (GB) of analog or digital channels, carrying, for example, television, radio or data services.
