Abstract (en)
[origin: EP0419990A2] The information display system contains a plurality of information carriers arranged at various points and formed by display modules (4, 5, 6). These display modules (4, 5, 6) are connected via a power-feeding and communication line formed by a two-wire line (2, 3) to a central power-feeding and control device (1). The system is equipped for bidirectional data traffic between the central power-feeding and control device (1) and the modules (4, 5, 6). This system provides for reliable and rational display of information items of all types and is particularly suitable as a seat reservation system for railway trains. <IMAGE>
