Information processing device
First Claim
1. A presenter device, comprising:
- a display unit on the presenter device configured to display at least one of a plurality of data files;
a first information providing unit on the presenter device configured to transmit to a host computer which is separate and distinct from the presenter device, a first information file coded in a markup language, the first information file including a command instructing a client device, separate and distinct from the presenter device, to access the host computer to reread the first information file after a preset time interval, and a predetermined filename coded within the first information file, the predetermined filename representing an image file to be displayed, the first information file configured to be read by the client device containing code causing the client device to download and display an image file having the predetermined filename;
a display switch unit on the presenter device configured to switch onscreen representation on the display unit between the plurality of data files;
a file generation unit on the presenter device configured to generate a display image file corresponding to one of the plurality of data files being currently displayed on the display unit when the onscreen representation on the display unit has been switched; and
a second information providing unit on the presenter device configured to transmit the display image file generated by the file generation unit to the host computer when the onscreen representation on the display unit has been switched;
wherein the second information providing unit transmits the display image file to the host computer as a newly displayed image file, and assigns the same predetermined filename to the newly displayed image file, replacing any previous file having the predetermined filename, the code in the first information file causing the client device to display the newly displayed image file having the same predetermined file name when the first information file is reread from the host computer after the preset time interval.

3. A method to be implemented on a presenter device, comprising the steps of:
-
controlling a display unit on the presenter device to display at least one of a plurality of data files; transmitting by the presenter device, to a host computer which is separate and distinct from the presenter device, a first information file coded in a markup language, the first information file including a command instructing a client device, separate and distinct from the presenter device, to access the host computer to reread the first information file after a preset time interval and a predetermined filename coded within the first information file, the predetermined filename representing an image file to be displayed, the first information file configured to be read by the client device containing code causing the client device to download and display an image file having the predetermined filename; switching by the presenter device onscreen representation on the display unit between the plurality of data files; generating by the presenter device a display image file corresponding to one of the plurality of data files being currently displayed on the display unit when the onscreen representation on the display unit has been switched; and transmitting by the presenter device the display image file to the host computer when the onscreen representation on the display unit has been switched; wherein the display image file is transmitted to the host computer as a newly displayed image file having the predetermined filename assigned as the filename of the newly displayed image file, replacing any previous file having the predetermined filename, the code in the first information file causing the client device to display the newly displayed image file having the same predetermined file name when the first information file is reread from the host computer after the preset time interval. - View Dependent Claims (4)

5. A computer readable medium having computer readable instruction stored thereon, which, when executed by a processor of a presenter device, configures the processor to perform the steps of:
-
controlling a display unit on the presenter device to display at least one of a plurality of data files; transmitting, to a host computer, which is separate and distinct from the presenter device, a first information file coded in a markup language, the first information file including a command instructing a client device, separate and distinct from the presenter device, to access the host computer to reread the first information file after a preset time interval and a predetermined filename coded within the first information file, the predetermined filename representing an image file to be displayed, the first information file configured to be read by the client device containing code causing the client device to download and display an image file having the predetermined filename; switching onscreen representation on the display unit between the plurality of data files; generating a display image file corresponding to one of the plurality of data files being currently displayed on the display unit when the onscreen representation on the display unit has been switched; and transmitting the display image file to the host computer when the onscreen representation on the display unit has been switched; wherein the display image file is transmitted to the host computer as a newly displayed image file having the predetermined filename assigned as the filename of the newly displayed image file, replacing any previous file having the predetermined filename, the code in the first information file causing the client device to display the newly displayed image file having the same predetermined file name when the first information file is reread from the host computer after the preset time interval.
