  • Patent number: 7973677
    Abstract: A system and a method for data transmission between at least one display screen and a remote client system. A first request to send a message via a first communication protocol is caused to be displayed on the display screen, and the message is transmitted to the remote client system via a second communication protocol. A control unit monitors the remote client system. The system induces the generation, and display on the display screen, of a request for confirmation of the first request, by the intermediary of a communication interface, which interface is designed to receive and generate messages in the first communication protocol, as well as to receive and generate messages suitable for being received by the control unit.
