In order to assist the user in retrieving the items of interest, a menu structure is transmitted as well. The menu structure renders it possible to access the database in various ways. Rather than including programme items (such as known form teletext systems), the transmitted menus refer to programme items. Where necessary, references can be made to programme information transmitted by different TV stations.
