Abstract
The invention relates to a method and an arrangement of assigning an information-category and a priority of exposure for spots or blocks of information in a digital information system comprising interfaces for data and telecommunication for round-the-clock transmission of information at places accessible to and frequented by the general public including places where television sets are placed, such that a control center has communication interfaces for coordinating and controlling display devices, with the control center being able to create and update an exposure list in real time. The exposure list contains information including how many times an information is to be exposed during a specific time period. Single spots or blocks of information to a specific information-category and a priority for exposure. The information is displayed according to the assigned priority, thus exposure interruption due to visual inaccessibility for information viewers is evened out during said specific time period for single spot or block information.
