Abstract
On the transmission side, a background picture and objects #1 to #3 are transmitted at a transmission rate R/4 each. On the reception side, a picture composed of the objects #1 to #3 and the background picture is displayed with a particular spatial resolution and a particular temporal resolution. In this case, on the reception side, when the object #1 is dragged at particular time t1, on the transmission side, as shown in FIG. 16 (A), the transmission of the background picture and the objects #2 and #3 is stopped. Only the object #1 is transmitted at the transmission rate R of the transmission path. Thus, a picture of which the spatial resolution of the object #1 dragged is improved is displayed at the sacrifice of the temporal resolution of the picture.
