Abstract: By reconfiguring configuration information items according to the need, it was made possible to implement a natural displayed scene. Initialize the time “t” to “0” , extract the attribute information item (position, size and display time information) of every (object) from the configuration information items sent from a communication network after getting through the step and detect the objects coincident in display time with the time “t” . Then, acquire an inclusive relation (correlation) between individual (objects) from the position and size information of the detected nodes (objects), reconfigure the configuration information items on the basis of the inclusive relation, further advance the time “t” by a predetermined frame rate and thereafter return to the step to repeat the above processing.
