ABSTRACT:
An interactive television system includes a plurality of client devices connected to a server through a network. The client devices display broadcast contents based on received broadcast data. Icon buttons are displayed superimposed on the displayed broadcast contents. Each icon button represents a different icon. When one of the displayed icon buttons is selected at one of the client devices, then the client device sends a request to the server, asking to execute, at another client device, an icon represented by the selected icon button. When the server receives the request over the network, the server sends icon identification data that corresponds to the icon over the network to the other client device. The other client device executes the icon based on the received icon identification data.
