A master display device 10a and slave display devices 10b and 10c share structured display information in which a plurality of html fragmentary information items each including display data are structured through communication via a network and further produce the same display on the basis of the structured display information. The master display device 10a, upon modifying the html fragmentary information item, sends the slave display devices 10b and 10c a notice reporting that the html fragmentary information item is modified and an ID (ID information) for identifying the modified html fragmentary information item. |
