Controlling displays in public spaces, e.g. bus stations, via data networks, with the display linked to a multimedia database via a first network and linked to display control via a second network for customer control

摘要

Information display system has at least one display device (30) for information, especially multi-media information such as advertising, with said information supplied from a database via a data transfer network (10), especially a mobile phone network, and a control device (22), for controlling the display via a second network (20) such as a bluetooth network. The control device can be coupled to a user's mobile phone (21). An Independent claim is made for a method for controlling a large display in a public space used data transmitted over one data network and control transmitted over a second network.
