Abstract (en)
[origin: EP0310475A2] The duration (7) of display of advertisements on display screens (3, 15) is controlled by coupling the duration of display to a duration of a telephone communication made from a public telephone kiosk (1, 2) near the display panel. Preferably, the communication made from this kiosk is paid for by means of a prepaid memory card (6). This memory card furthermore contains a storage zone (9) in which may be recorded an advertisement which is precisely the message to be displayed. <??>Refer to single Figure 1. <IMAGE>
