Image reproduction devices and a management device each hold moving image data. The management device goes into a reproduction standby state in which the moving image data can be reproduced and instructs the image reproduction devices to go into the reproduction standby state, by cascade communication. The management device starts reproduction of the moving image data and instructs the image reproduction devices to start reproduction of the moving image data, by broadcast communication. The management device periodically broadcasts synchronization information. The image reproduction devices use the synchronization information to specify a frame number of a frame displayed on the management device. Frames corresponding to the specified frame number are displayed on the display parts. |
