Abstract
Przedmiotem wynalazku jest sposób znakowania używanych do wykrywania i pomiaru wycieków w sieciach telewizji kablowej, wykorzystujący dodatkowe sygnały nadawane w tych sieciach niosące informacje znakującą. Zgodnie z wynalazkiem, wąskopasmowy sygnał lub sygnały znakujące umieszcza się w nieużywanych częściach widma dowolnego, wykorzystywanego w sieci kanału telewizji kablowej, w szczególności w pasmach ochronnych (GB) kanałów analogowych lub cyfrowych, niosących na przykład usługi telewizji, radia lub transmisji danych.
