Image reproduction devices (10a to 10e) and a management device (20) respectively retain moving image data. The management device (20) shifts to a reproduction standby state of the moving image data (50), and instructs the image reproduction devices (10a to 10e) to shift to the reproduction standby state, using cascade communication. The management device (20) starts reproduction of the moving image data (50), and instructs the image reproduction devices (10a to 10e) to start reproduction of the moving image data (50), using broadcast communication. The management device (20) periodically broadcasts synchronization information (252). The image reproduction devices (10a to 10e) use the synchronization information (252) to specify a frame number displayed on the management device (20). A frame corresponding to the specified frame number is displayed on the display units (110a to 110e). |
