According to the invention, a server system (1) is connected to a number of remote display means (5-7) for messages for broadcasting, by means of a communication network (8). The audiovisual messages (4) received from the server system (1) are made perceptible for the clients (2, 3). The clients can send coded instruction signals (16) to a first access means (5a-7a), located near a display means (5-7), by means of portable client badges (14, 15), which are transmitted to the server system (1) which then establishes a back-up communication (18) with the client (2), for example by means of the portable telephone thereof. The client can thus simply establish communication and, when the server system (1) has information specifically concerning the above, said information need not be transmitted over the network.
Selon l~invention, un système serveur (1) est relié par un réseau de communication (8) à une pluralité de moyens de visualisation (5-7) de messages à diffuser placés à distance. Les messages audiovisuels (4) reçus du système serveur (1) sont rendus perceptibles par les clients (2, 3). A l~aide de badges portables de clients (14, 15), les clients (2, 3) peuvent envoyer à un premier moyen d~accès (5a-7a) placé à proximité d~un moyen de visualisation (5- 7) des signaux d~instruction codés (16) qui sont transmis au système serveur (1), lequel établit ensuite une communication de suivi (18) avec le client (2) par exemple sur son téléphone portable. Le client peut ainsi établir de manière simple une communication et, lorsque le système serveur (1) dispose déjà des informations spécifiques le concernant, celles-ci n~ont pas à être transmises sur le réseau.
