PURPOSE:To relax a limitation on the setting up of a device and to reduce noise interference through the ground by performing transmission between a communication control terminal and a display controller, a display device with a radio transmission system. CONSTITUTION:Image information formed by the communication control terminal 3 is formed into a file of a bit map, and the control terminal 3 ink structs the display controllers 4a, for display and transfer of files and controls them by ID numbers through respective radio interfaces. A radio interface device 7 uses a specified small power source, and error correction and retransmission are performed between radio units. The display controller 4a stores receiving the display instruction data and the image bit map file in an HDD 5i at a format matching with the size of the display device 6a. The display controller 4a reproduces the bit map file by the instructed display instruction data to convert it into a video signal. The large-sized display device 6a reproduces the video signal and display it. |
