Abstract

A picture display device displays a video signal supplied from a data process device. Bi-directional communication is carried out with each of a plurality of data process devices. A plurality of video signals is combined into one screen corresponding to information of the picture size of each of the plurality of video signals obtained by the bi-directional communication with each of the plurality of data process devices. A video signal, outputted when the plurality of video signals is combined, is displayed. A second control signal is generated which controls the plurality of data process devices and which corresponds to a first control signal that corresponds to a user operation. The first control signal and the second control signal are transmitted to the plurality of data process devices. The plurality of data process devices also communicate bi-directionally with each other.
