Image reproduction devices (10a to 10e) and a management device (20) each hold moving image data. The management device (20) goes into a reproduction standby state in which the moving image data (50) can be reproduced and instructs the image reproduction devices (10a to 10e) to go into the reproduction standby state, by 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), by 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 of a frame displayed on the management device (20). Frames corresponding to the specified frame number are displayed on the display parts (110a to 110e). |
