PROBLEM TO BE SOLVED: To obtain a comfortable display response without disturbing a screen in the case where drawing is repeatedly updated in the same region within a short time in an SBC system. SOLUTION: In the case where drawing data to be sequentially generated and updated by a server are received by a client in response to continuous input events of the client, in a client device, the received drawing data are stored in a receiving buffer 32a after adding a receiving time to the head of the drawing data. In the case where next drawing data are not received within a fixed time from the receiving time of the received drawing data, the received drawing data are displayed and if received, display positions and sizes are compared between the drawing data received the last time and received the present time, thereby determining whether or not the drawing data received the present time conceal the drawing data received the last time. If the conceal is determined, the drawing data received the last time are deleted from the receiving buffer 32a without display processing and if non-conceal is determined, the drawing data received the last time are displayed and then deleted from the receiving buffer 32a.
