Abstract (en)
[origin: WO02073132A1] In order to make information data available for users, in particular in vehicle navigation systems, information data is divided among various transmission media by means of a categorisation. The categorisation is carried out into information data of a global type, a regional type and individual type. Global type information data is retained by the users (4), regional type information data is distributed by a point-to-multipoint method, information data of an individual type is only requested where needed and transmitted to a user (4) by a point-to-point method.
