Abstract
Method for communication between a central server and a computerized juke-box which operates in a conference mode, including: sending a header before any transaction, which includes the identity of the destination together, the identity of the emitter, and the size of the packets; responding from the server in the form of a data packet, each packet sent by the server being encoded using the identification code of the juke-box software; and receiving a data packet by the juke-box, which decodes the packet, simultaneously performs a check on the data received by the CRC method and sends an acknowledgment of receipt to the server indicating the accuracy of the information received, to allow it to prepare and send another packet to the juke-box.
