PROBLEM TO BE SOLVED: To execute an operation for presentation from a free position in a floor where a display device is installed or while it is moved by providing a display control means for displaying a picture received by a radio LAN receiver on PDP. SOLUTION: When reception data is inputted from a radio LAN receiver 31, a control processing part 32 executes a prescribed data processing and obtains display data. Obtained display data is transferred to a display processing part 33, a picture quality improvement processing is executed and RGB signals are obtained. When the probe of a switch 23 is connected to an (a) side terminal, the RGB signals outputted from the display processing part 33 are sent to an A/D conversion processing part 24, are converted into digital RGB data, and are sent to a control part 25. Frame rate scanning conversion is executed on data and data are sent to PDP 26. Thus, a presentation picture sent from an operation side device 1 by radio is displayed on PDP 26.
