发明名称 TRANSMISSION OF AN ELECTRONIC DATABASE OF INFORMATION
摘要 Method and arrangements for transmitting and receiving an electronic database, e.g. an electronic television programme guide. The database includes a plurality of programme items. 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.
