A method and apparatus are provided for transmitting content display data between a server and at least one client terminal, whereby said data are arranged into nodes of a hierarchical tree including at least one parent node and at least one son node, a displayable element being associated with each node. One such method includes the following steps in which: the server transmits a simplified representation of the tree to the client, said representation including, for at least some of the nodes, only information for locating the displayable element in the content to be displayed; the client terminal selects at least one node of interest from the simplified representation as a function of a criterion relating to the distance from the client to the displayable element that is associated with the node of interest in the content to be displayed; and geographical data are transmitted in order to enable said displayable element to be reconstructed for the selected nodes(s) of interest.
