4. The system according to claim 1, wherein at least one of said screen information processing unit to be provided in the operating-side information equipment and said screen information processing unit to be provided in the operated-side information equipment includes a function for modifying the view region display priority, each of which follows and modifies the display priority of the view regions of which the assigned window is common to each screen information processing unit in a mutual manner.

5. The system according to claim 1, wherein at least one of said screen information processing unit to be provided in the operating-side information equipment and said screen information processing unit to be provided in the operated-side information equipment includes a function for modifying the view region display priority, each of which follows and modifies the display priority of the view region with which the assigned window is correlated in a mutual manner.

6. The system according to claim 1, wherein said view information includes information regarding an entire screen view for displaying the entire screen of the operated-side display unit.

7. The system according to claim 1, wherein said control information processing unit to be provided in the operated-side information equipment includes a function for giving instructions for changing the window to be operated to the operating system such that in response to the selection information of a view region to be operated from the operating-side information equipment, and in the event that the assigned window of the view region to be operated does not agree with the window to be operated in the operated-side information equipment, the window to be operated becomes the assigned window of the view region.

8. The system according to claim 1, wherein said screen display processing unit to be provided in the operating-side information equipment includes a function in which in the event that the assigned window of the view region corresponding to the image displayed on the display region of the operating-side display unit is not the window to be operated, the image operated the last time is continuously displayed without updating screen display.

9. The system according to claim 1, wherein said control information processing unit to be provided in the operating-side information equipment includes a function for changing the display priority of the view information stored in the view region storing unit.

10. The system according to claim 1, wherein said screen display processing unit to be provided in the operating-side information equipment includes a function for controlling the operating-side display unit to display identification display indicating whether or not the assigned window of the respective view regions corresponding to an image displayed on each display region of the operating-side display unit is the window to be operated.

11. The system according to claim 1, wherein said screen display processing unit to be provided in the operating-side information equipment includes a function for controlling the operating-side display unit to display positional display indicating relative positional relations between the operated-side display unit, the window to be operated, and the display region of the operating-side display unit.
