  • the present invention relates to a communication system for supplying information.
  • the present invention furthermore relates to a system, as well as to a transceiver, a central unit and a node for use in the system, with which information can be supplied.
  • Supplying information is in this case more particularly about known systems for supplying auditive information.
  • various systems are known for supplying informati- on, for example in museums, at exhibitions, manifestations or fairs, on that which is to be seen, heard or experienced there.
  • Known systems provide information centrally by means of a cassette recorder to a transmitter, and from there this information is transferred to several receivers, where the said information can be simultaneously heard by the possessor of the receiver.
  • Another known possibility is to provide each user with his own cassette recorder, so that the user can select the recorded information by starting, stopping and winding on or rewinding as desired, and tune in to that which can be seen or heard at that particular location.
  • the object of the present invention is to provide a full communication system with which at wish audio with or without video information can be selected by a user on an individual basis, which information then becomes available to the user in a personalised way, as well as to provide transducers in such a communication system which is inexpensive to produce, which may for example be used to supply in a limited area of action individually selected information to different visitors of museums, exhibitions, manifestations and fairs, but which may also be used to gather personal orders given by the persons during their shopping.

  • the central unit comprises a main memory wherein digital information is stored in information blocks containing audio and/or video data, whereby only a person holding a transceiver within the radius of action of the communication means is capable of requesting the transfer of one or more of the blocks, which blocks are selectable by the person holding the transceiver by means of activating selection means by inputting reference data provided on displayed objects about which said person wants to be informed, whereby after said selection the selection data is transmitted to the central unit on the basis whereof the corresponding selected blocks are being searched for in the main memory of the central unit and sent to the requesting transceiver, whereupon one personalised block of the locally available selected blocks is further selected for conversion of its audio and/or video data into audible and/or visible information on a moment

  • the information is fully personally directed at the user in question, who is able to choose from—those information blocks that he wishes to receive and listen to or view at. Because selected information blocks are respectively transferred from the central unit to the respective requesting transceiver, the total communication time is minimal and thus it is possible to provide several transceivers with the information desired practically simultaneously.
  • the system according to the invention is advantageously applicable during shopping such as in a supermarket where ones choice can be selected upon viewing the articles.
  • the corresponding article identification data is then transmitted to the repository to collect the selected articles there.
  • All selected products are brought to a delivery place for payment and distribution to the costumer. Payment could advantageously take place by including a credit card reader in the transceiver, in order to automatically deduct the amount to be paid from the customers account.
  • a further advantage of the application of the communication system according to the invention is that if pieces are added in a hall or exhibition space, these alterations do not make it necessary to change the digital information stored in the central unit as well.

Abstract

L'invention concerne un système de communication destiné à fournir des informations, par exemple sur des objets exposés, à des utilisateurs munis chacun d'un émetteur-récepteur portatif relié à une unité centrale dans laquelle des informations numériques sont conservées dans des blocs susceptibles d'être choisis individuellement, à la demande de chaque émetteur-récepteur individuel, puis d'être transférés et mémorisés dans ledit émetteur-récepteur, ce système permettant ainsi que les blocs d'informations choisis et mémorisés soient convertis dans l'émetteur-récepteur en informations visibles et audibles, à la demande de l'utilisateur. Lorsque l'on utilise un tel système, la compression des informations transférées et mémorisées requiert un temps de transmission ainsi qu'un encombrement de mémoire minimes. Ce système de communication s'effectue sans fil au moyen d'un rayonnement infrarouge dans la zone d'action. En outre, l'invention décrit un dispositif autonome permettant de convertir les blocs d'informations en sons audibles et en images visibles.
