PROBLEM TO BE SOLVED: To make it possible to display information sent through an electronic white board provided at the terminal on a sending side even on a terminal equipped with no electric white board by a method wherein both or either one of image signals and graphic signals selected by a selecting means are displayed on an image outputting means. SOLUTION: An electronic white board device 14 multiplexes input image signals, audio signals and graphic signals. The multiplexed signals as sending signals are outputted to a circuit network 30 so as to be received by a receiving side terminal 20. The sending signals received by the receiving side terminal 20 are inputted to an electronic board displaying device 21. The electronic white board displaying device 21 divides the sending signals respectively into the image signals, the audio signals and the graphic signals. Next, the image signals, the audio signals and the graphic signals are outputted to a monitor 22. The monitor 22 displays images or the like biased on the image signals or the like. On the other hand, the audio signals are outputted to a speaker 23, which outputs voices or the like on the basis of the audio signals. |
