Abstract

A system includes an information processing apparatus and a display. The apparatus has at least one processor coupled via a bus to a memory, the processor being programmed to control one or more of a content generation unit to generate content for display, wherein the content includes a page having a plurality of content elements, an ID generating unit to generate content IDs corresponding to each of the content elements in the generated page, a content refresh determination unit to determine a content ID of at least one content element to be refreshed on the display, and a device driver to receive the generated content and transmit instructions to the display to cause display of the content. The device driver receives the content ID for the at least one content element to be refreshed, and transmits instructions to cause refresh of the at least one content element corresponding to the content ID at the identified page location.

Claims

1. A system comprising:

an information processing apparatus; and

a display configured to display content from the information processing apparatus,

wherein the information processing apparatus comprises;

at least one processor coupled via a bus to a memory, the processor being programmed to control one or more of;

a content generation unit configured to generate content for display, wherein the content comprises a page having a plurality of content elements;

an ID generating unit configured to generate content IDs corresponding to each of the content elements in the page of the content generated by the content generation unit;

a content refresh determination unit configured to determine a content ID of at least one content element to be refreshed on the display; and

a device driver configured to receive the content generated by the content generation unit and transmit instructions to the display to cause display of the content thereon,

wherein the device driver is configured to receive the content ID for the at least one content element to be refreshed on the display, as determined by the content refresh determination unit, identify a location of the at least one content element on the displayed page based on the content ID, and transmit instructions to cause the display to refresh the at least one content element corresponding to the content ID at the identified page location.

2. The system according to claim 1, wherein the device driver is configured to transmit instructions to refresh the at least one content element corresponding to the content ID, without refreshing the rest of the page.

3. The system according to claim 1, wherein the ID generating unit is configured to generate a content ID that is associated with information identifying the page to which the content element belongs.

4. The system according to claim 1, wherein the ID generating unit is configured to generate a content ID that is associated with information identifying a type of the content element.

5. The system according to claim 4, wherein the type of content element comprises at least one of an image, button, text, content, dialog, menu and item.

6. The system according to claim 1, wherein the ID generating unit is further configured to generate a page ID for each page of content generated by the content generation unit, the page ID being associated with information identifying each content element in the page.

7. The system according to claim 6, wherein the device driver is configured to identify the location of the at least one content element on the displayed page by referring to the information associated with the page ID of the page.

8. The system according to claim 6, wherein the page ID is associated with information identifying a row and a column where a content element is located in an image included in the page.

9. The system according to claim 1, wherein the display is either separate from or integrated into the information processing apparatus.

10. A method of displaying content from an information processing apparatus on a display, the method comprising:

generating the content for display, the content comprising a page having a plurality of content elements;

generating content IDs corresponding to each of the content elements in the generated content page;

determining a content ID of at least one content element to be refreshed on the display;

displaying the generated content including the page on the display;

identifying a location of the at least one content element to be refreshed on the displayed page based on the content ID of the at least one content element; and

refreshing the at least one content element corresponding to the content ID at the identified page location on the display.

11. A computer readable medium having stored thereon computer executable instructions for displaying content from an information processing apparatus on a display according to the method of claim 10.

12. An information processing apparatus configured to provide content for a display, the information processing apparatus comprising:

at least one processor coupled via a bus to a memory, the processor being programmed to control one or more of;

a content generation unit configured to generate the content for the display, wherein the content comprises a page having a plurality of content elements;

an ID generating unit configured to generate content IDs corresponding to each of the content elements in the page of the content generated by the content generation unit;

a content refresh determination unit configured to determine a content ID of at least one content element to be refreshed on the display; and

a device driver configured to receive the content generated by the content generation unit and transmit instructions to the display to cause display of the content thereon,

wherein the device driver is configured to receive the content ID for the at least one content element to be refreshed on the display, as determined by the content refresh determination unit, identify a location of the at least one content element on the displayed page based on the content ID, and transmit instructions to cause the display to refresh the at least one content element corresponding to the content ID at the identified page location.

13. A method of providing content for a display from an information processing apparatus, the method comprising:

generating the content for the display, wherein the content comprises a page having a plurality of content elements;

generating content IDs corresponding to each of the content elements in the generated content page;

determining a content ID of at least one content element to be refreshed on the display; and

transmitting instructions to the display to cause display of the generated content thereon including the page;

identifying a location of the at least one content element to be refreshed on the displayed page based on the content ID of the at least one content element; and

transmitting instructions to the display to cause refreshing of the at least one content element corresponding to the content ID at the identified page location.

14. A computer readable medium having stored thereon computer executable instructions for providing content for a display from an information processing apparatus according to the method of claim 13.
