Abstract

A request for a document from a mobile device via a network is received. In response to the request, within the document a non-textual document element unrecognizable to the mobile device is identified. Within the document, at a first location associated with the non-textual document element, a start marker comprising a first code selected from a predetermined Unicode range is inserted. Within the document, at a second location associated with the non-textual document element, an end marker comprising a second code selected from the predetermined Unicode range is inserted. The second code has a predetermined relationship to the first code. The document is transmitted to the mobile device via the network.

First claim

The invention claimed is:

1. A method comprising:
receiving a request for a document from a mobile device via a network;
in response to the request, identifying within the document a non-textual document element unrecognizable to the mobile device;
inserting within the document, at a first location associated with the non-textual document element, a start marker comprising a first code selected from a predetermined Unicode range;
inserting within the document, at a second location associated with the non-textual document element, an end marker comprising a second code selected from the predetermined Unicode range and having a predetermined relationship to the first code, wherein the predetermined Unicode range falls between \uE900 to \uEFFF; and
transmitting the document to the mobile device via the network.

2. The method of claim 1 further comprising:
identifying within the document a textual document element unrecognizable to the mobile device; and
inserting within the document, at a third location associated with the textual document element, a single marker comprising a third code selected from a second predetermined Unicode range.

3. The method of claim 1 wherein the mobile device inserts between the first and second locations associated with the non-textual document element a graphical representation when displaying the document.

4. The method of claim 3 wherein the document is displayed to a user using the mobile device via a webpage.

5. The method of claim 1 wherein the predetermined Unicode range is dedicated for special purposes.

6. The method of claim 1 wherein the non-textual document element comprises one of:
an image;
a photograph;
a video;
a chart;
a table; and
a graph.

7. The method of claim 1 wherein the first code has a first value and the second code has a second value that is one less than the first value.

8. The method of claim 1 wherein the first code is an odd number and the second code is an even number.

9. A method comprising:
receiving a request for a document from a mobile device via a network;
in response to the request, identifying within the document first and second document elements unrecognizable to the mobile device;
inserting within the document, at a first location associated with the first document element, a start marker comprising a first code selected from a first predetermined Unicode range;
inserting within the document, at a second location associated with the first document element, an end marker comprising a second code selected from the first predetermined Unicode range and having a predetermined relationship to the first code;
inserting within the document, at a third location associated with the second document element, a first marker comprising a third code selected from a second predetermined Unicode range, wherein the first predetermined Unicode range falls between \uE900 to \uEFFF and the second predetermined Unicode falls between \uE900 to \uEBFF; and
transmitting the document to the mobile device via the network.

10. The method of claim 9 wherein the mobile device inserts between the first and second location associated with the first document element a first graphical representation and inserts at the third location associated with the second document element a second graphical representation substantially similar to the first graphical representation when displaying the document.

11. The method of claim 10 wherein the document is displayed to a user using the mobile device via a webpage.

12. The method of claim 9 wherein the first and second predetermined Unicode ranges are dedicated for special purposes.

13. A non-transitory computer readable medium having program instructions stored thereon, the instructions capable of execution by a processor and defining the steps of:
receiving a request for a document from a mobile device via a network;
in response to the request, identifying within the document a non-textual document element unrecognizable to the mobile device;
inserting within the document, at a first location associated with the non-textual document element, a start marker comprising a first code selected from a predetermined Unicode range;
inserting within the document, at a second location associated with the non-textual document element, an end marker comprising a second code selected from the predetermined Unicode range and having a predetermined relationship to the first code, wherein the predetermined Unicode range falls between \uE900 to \uEFFF; and
transmitting the document to the mobile device via the network.

14. The non-transitory computer readable medium of claim 13 , further comprising instructions defining the step of:
identifying within the document a textual document element unrecognizable to the mobile device; and
inserting within the document, at a third location associated with the textual document element, a single marker comprising a third code selected from a second predetermined Unicode range.

15. The non-transitory computer readable medium of claim 13 , wherein the mobile device inserts between the first and second location associated with the non-textual document element a graphical representation when displaying the document.

16. The non-transitory computer readable medium of claim 15 , wherein the document is displayed to a user using the mobile device via a webpage.

17. The non-transitory computer readable medium of claim 13 , wherein the predetermined Unicode range is dedicated for special purposes.

18. The non-transitory computer readable medium of claim 13 , wherein the non-textual document element comprises one of:
an image;
a photograph;
a video;
a chart;
a table; and
a graph.

19. The non-transitory computer readable medium of claim 13 , wherein the first code has a first value and the second code has a second value that is one less than the first value.

20. The non-transitory computer readable medium of claim 13 , wherein the first code is an odd number and the second code is an even number.
