PROBLEM TO BE SOLVED: To provide a data output device and a broadcasting system such that an attendance can bring back, in the form of electronic data without taking trouble to ask permission from the lecturer, some lecture material which can be brought back. SOLUTION: The data output device 1 can change pages of lecture material displayed on a screen etc., according to a switching indication made by the lecturer, and also discriminatingly output the pages of the lecture materials which can be saved and can not be saved. Consequently, the attendance can confirm contents by displaying the lecture material on a video display device 4 at hand even from a distance, and can save the pages of the lecture material which can be saved in a radio reception device 3 or the video display device 4.
