A bidirectional still picture information service system for providing the users with still picture information from an information service undertaker, through which communication data are displayed without increasing the burden of still picture broadcasting. An undertaker device transmits a natural picture for input/output to a user device by still picture broadcasting and the data are transmitted between the undertaker device and user device through a telephone line. The user device synthesizes the received still picture and data and displays the result of synthesis on the display of the user.
