An application execution unit executes a first application on the basis of operation information of a first inputting device by a first user to generate image data of the first application. A communication processing unit transmits operation information of a second inputting device by a second user to an external information processing device. An acquisition unit acquires image data of a second application from the external information processing device, the operation information of the second inputting device being reflected on the image data of the second application. A display processing unit displays a screen image of the first application and a screen image of the second application on a display device.
