Abstract

An object of the present invention is to provide a data distribution system which is suitable to distribute data to a mobile terminal device and the like to cause the mobile terminal device and the like to display an image, and a method therefor. In response to a request from a mobile communication device (2) through a web page distribution server (5), a web server (12) distributes document data shown in FIG. 2 to the web page distribution server (5). The web page distribution server (5) creates an image of the distributed document data, and divides the created image into a plurality of areas to thereby create divided area data. In response to the request from the mobile communication device (2), the webpage distribution server (5) sequentially distributes such components of the created divided area data as are to be actually displayed, to the mobile communication device (2). The mobile communication device (2) sequentially displays the divided area data distributed from the web page distribution server (5).

wherein the subject data further includes display area data which can be displayed in association with the display area within the image of the contents data, and the data display device further displays the display area data that is associated with the display area included in the image which is included in the divided area on the display screen according to display area position data indicative of the position of the display area in the image that is included in the divided area, and

wherein the display data producing means produces the display data including the display area data which is associated with the display area included in the image which is included in the divided area, and the display area position data indicative of the position of the display area in the image that is included in the divided area.

7. A data distribution device according to claim 6, wherein the display area data is a URL of a resource that can be accessed from the data display device.

8. A data distribution device according to claim 7, wherein the subject data is document data that is distributed from a resource that can be accessed from the data display device by the URL.

3. (canceled)

9. A data display device for displaying display data on a display screen having a given size upon receiving distribution of the display data that is used for displaying contents of subject data to be accessed, the display data being used for displaying any one of a plurality of divided areas obtained by dividing the contents of the subject data so that each of the divided areas is larger in size than the display screen, the data display device comprising:
