Abstract: In a screen displayed on site in a data format of image data, if a portion of the screen is changed, from among the image data of the entire screen, only an image data subjected to the change is converted to a vector graphics and is transmitted to a remote site via a network. At the remote site, the transmitted vector graphics is reconverted to the image data and is displayed. Further, information necessary for searching an image data is transmitted in association with a vector graphics. This allows a search to be made only from a data which actually requires to be displayed at the remote site.
