In a multi-user communication system in which communication is carried out between a display apparatus and multiple information terminal apparatuses (a moderator terminal apparatus and a user terminal apparatus) over a network, the moderator terminal apparatus sends, to the display apparatus, a data ID (ID information) for identifying data to be displayed in a display unit of the display apparatus, user information indicating a user that is an owner of that data, and access rights information that is set for each user using the information terminal apparatuses and that indicates whether or not the generation and changing of that data is permitted. The display apparatus displays the data identified by the data ID (ID information) in the display unit based on the user information and the access rights information. |
