Abstract

The invention relates to a digital information system (10) for displaying information on at least one display means with the aid of at least one projector (22). The exposures are presented at places accessible to and frequented by a general public. The information system (10) includes external information mediators (24) and information is controlled dynamically through the medium of a communication interface and through the medium of an exposure handler in a central computer (28). The inventive system also includes a communication interface (14) against an elective number of station computers (34) having connected projector computers (38) which control projectors (22) for displaying pictures or exposures. The station computers (34) and peripheral equipment are situated at mutually distanced places. According to one particular field of use, the places mentioned are subway stations (16, 18, 20) and projectors (22) project exposures or pictures onto display means positioned at selected places in the stations (16, 18, 20).

Description

technical field [0001] The present invention relates to a method and a device for controlling and coordinating projectors in a digital information system to display information on at least one display device by at least one projector of each said display device, said information being displayed at places frequently visited by the public. In particular, the invention is used to control projectors to display information to the public in places such as train stations, subways, airport lounges, movie theaters, private homes, and the like. Background technique [0002] Systems for displaying information in the form of advertisements, timetables or arrival and departure times on today's public services such as buses, trains, subways, etc. have a static nature. Such information is presented to viewers through bulletin boards, advertisements, diagrams, oral broadcasts from loudspeakers, and digital displays. The nature of this type of information medium is that it does not require c...
