| Zusammenfassung: | The invention relates to an arrangement for selecting frequency ranges to be used in return and forward interaction paths in an interaction channel of a digital video broadcasting system. The arrangement comprises first filtering means for filtering signals in the forward interaction path, second filtering means for filtering signals in the return interaction path and means for selecting sub-frequency ranges to be used in the forward interaction path and in the return interaction path from a number of predetermined sub-frequency ranges arranged into the first filtering means and into the second filtering means. The invention also relates to a method for arranging frequency ranges into a forward interaction path and into a return interaction path in a digital video broadcasting system. |
