Abstract

Systems and methods of retrieving and presenting partial (skipped) document content are provided. A typical system includes a document parsing stage, a device request for content stage and a delivery of requested content stage. A target device can include a device presentation of the requested content stage. The system parses the content of an electronic document and generates a document object model (DOM) representation of the electronic document, where each source and destination target is assigned a document object model identifier (DOM ID). In some instances, upon completion of parsing, the document object model is then paginated in computer memory into segments of a certain size called chunks; in such instances the pagination operation can update each DOM ID with an additional information attribute containing the chunk index with the purpose of establishing a relationship between a document object model identifier and the corresponding chunk index. Thus, when a device requests specific content corresponding to the DOM ID the chunk index value indicates the correct chunk to be returned to the device. The device initiates a document viewing experience by requesting, parsing and displaying an initial chunk of document content as delivered by the corresponding server. The device can, upon parsing the data chunk, record navigational information provided in the form of link information containing corresponding DOM ID and Chunk Index information. The link information can in certain instances be presented visually by a dotted underline.

1. A process for retrieving and viewing partial content of a server stored document on a mobile communication device, comprising:

extracting informational entities from said document within said server;

populating a model of said document within said server with elements corresponding to said informational entities;

detecting navigational entities within said informational entities and in response storing within said server source and target destinations associated with said navigational entities;

assigning an identifier to each of said source and target destinations within said model;

paginating said model within said server into a plurality of segments identified by respective index values, comprising updating each said identifier with an attribute containing a corresponding one of said index values;

generating output data for delivery to said mobile communication device by traversing through said elements in said model and recording each element as an equivalent command containing content and document characteristics;

sending a first request from the mobile communication device to the server to display said document;

in response to receiving said first request transmitting a first segment of said output data from said server to said mobile communication device;

parsing said output data within said mobile communication device and executing each said equivalent command to thereby display said content of said first segment of the document according to said document characteristics comprising any of said navigational entities contained within said first segment;

in response to user selection of a navigational entity displayed on said mobile communication device sending a further request to said server containing the identifier and index value corresponding to said navigational entity;

in response to receiving said further request transmitting a further segment of said output data from said server to said mobile communication device from a location in said model corresponding to said index, wherein the location of said further segment is independent of the location of said first segment within said document;

parsing said further segment of output data within said mobile communication device and executing each said equivalent command to thereby display said content of said further segment of the document according to said document characteristics; and

detecting within said mobile communication device any skipped content between said first and further segment and providing a visual indication of said skipped content on said mobile communication device.

2. The process of claim 1, wherein said visual indication of said skipped content includes a horizontal bar indicator between said first and further segment displayed on said mobile communication device.

3. The process of claim 2, further including calculating and displaying size of said skipped content within said horizontal bar indicator

4. The process of claim 1, wherein said extracting further includes parsing said document using a document distiller.

5. The process of claim 1, wherein each of said informational entities includes at least one of textual paragraphs, font type, font size, font style, table of contents, bookmarks, and hyperlinks.

6. The process of claim 1, wherein said parsing further includes binary examination of said document.

7. The process of claim 6, wherein said binary examination further includes executing specific parsing rules according to a type associated with said document.

8. The process of claim 1, wherein each of said navigation entities includes at least one of a table of content, hyperlinks, and bookmarks.

9. The process of claim 1, wherein said paginating is performed by said server upon receipt of said first request.

10. The process of claim 1, wherein said output data is in Universal Content Stream format.

11. The process of claim 1, wherein said navigational entities are displayed on said mobile communication device as underlined link text.

12. The process of claim 11, wherein said underlined link text is a selectable client control to allow invocation of said further request.

13. The process of claim 1, wherein said horizontal bar indicator is a selectable client control to allow invocation of an additional request for the server to transmit an additional segment of said output data subsequent to said first segment for display on said mobile communication device.

14. A mobile communication device process comprising:

sending a first request outside said mobile communication device to display a document stored outside said mobile communication device;

receiving and parsing output data from outside said mobile communication device corresponding to a first segment of said document, said output data comprising commands containing content and document characteristics;

parsing said output data and executing each of said commands to thereby display the content of said first segment of the document according to said document characteristics comprising any navigational entities contained within said first segment;

in response to user selection of a navigational entity sending a further request outside said mobile communication device containing an identifier and index value corresponding to said navigational entity;

receiving and parsing a further segment of output data from outside said mobile communication device corresponding to a further segment of said document, wherein the location of said further segment is independent of the location of said first segment within said document;

parsing said further segment of output data and executing each command therein to thereby display the content of said further segment of the document according to said document characteristics; and

detecting within said mobile communication device any skipped content between said first and further segment and providing a visual indication of said skipped content.

15. The mobile communication device process of claim 14, wherein said visual indication of said skipped content includes a horizontal bar indicator between said first and further segment.

16. The mobile communication device process of claim 15, further including calculating and displaying size of said skipped content within said horizontal bar indicator.

17. The mobile communication device process of claim 14, wherein said document characteristics include at least one of textual paragraphs, font type, font size, font style, table of contents, bookmarks, and hyperlinks.

18. The mobile communication device process of claim 14, wherein each of said navigation entities includes at least one of a table of content, hyperlinks, and bookmarks.

19. The mobile communication device process of claim 14, wherein said output data is in Universal Content Stream format.
