Abstract

A request is sent from a client device to a host device hosting an application capable of providing a split window view of content. Generation of a split window associated with execution of the application on the host device may include at least two split windows. Information regarding the split windows may be sent from the host device to the client device over the communication network. The client device may then use information regarding a first split window to generate an image display corresponding to the first split window. In addition, the client device may process the information regarding a second split window to stitch an image display corresponding to the second split window to the image display corresponding to the first split window. As such, upon scrolling of the display of the client device, the image display corresponding to the second split window may be displayed.

Claims

1. A method for using split windows for cross-platform document views, the method comprising:

receiving a request sent over a communication network from a client device having a single display screen, the request concerning application display information for a content file accessible via an application;

executing instructions stored in memory of a host device having a single display screen, wherein execution of the instructions by a processor executes the application to access the content file, wherein execution of the application generates on the single display screen of the host device a split window view of the content file, the split window view comprising at least two split windows, each split window independently providing a view of a portion of the content file;

sending an image of a first split window of the at least two split windows over the communication network to the client device, wherein the single display screen of the client device displays the image on the client device corresponding to the first split window of the at least two split windows in the single display screen of the host device;

scrolling through the content file via a second split window of the at least two split windows in the single display screen of the host device;

capturing a plurality of different images corresponding to the second split window of the at least two split windows as the second split window in the single display screen of the host device scrolls through the content file, wherein each of the plurality of images corresponds to a different portion of the scrolled content file; and

sending the captured images over the communication network to the client device, wherein the client device;

stitches the captured images together to generate an image display corresponding to the second split window, and

stitches the image display corresponding to the second split window to the image of the first split window currently displayed in the single display screen of the client device, and wherein the image display corresponding to the second split window is not viewable until a scrolling action is received on the client device.

2. The method of claim 1, wherein the second split window scrolls through the content file.

3. The method of claim 2, wherein the second split window automatically scrolls to a next portion of the content file when an image of a previous portion of the content file is captured.

4. The method of claim 2, wherein the plurality of different images are captured as the second split window scrolls to the different corresponding portions of the content file.

5. The method of claim 1, wherein the stitched image display collectively provide an image of the entire content file.

6. An apparatus for using split windows for cross-platform document views, the apparatus comprising:

a communication interface for receiving a request sent over a communication network from a client device having a single display screen, the request concerning application display information for a content file accessible via an application; and

a processor for executing instructions stored in memory of a host device having a single display screen, wherein execution of the instructions by the processor executes the application to access the content file, wherein execution of the application generates on the single display screen of the host device a split window view of the content file, the split window view comprising at least two split windows, each split window independent providing a view of a portion of the content file;

wherein the communication interface sends an image of a first split window of the at least two split windows over the communication network to the client device, wherein the single display screen of the client device displays the image on the client device corresponding to the first split window of the at least two split windows in the single display screen of the host device;

wherein the processor executes further instructions to scroll through the content file via a second split window of the at least two split windows in the single display screen of the host device and capture a plurality of different images corresponding to the second split window of the at least two split windows as the second split window in the single display screen of the host device scrolls through the content file, wherein each of the plurality of images corresponds to a different portion of the scrolled content file; and

wherein the communication interface sends the captured images over the communication network to the client device, wherein the client device;

stitches the captured images together to generate an image display corresponding to the second split window, and

stitches the image display corresponding to the second split window to the image of the first split window currently displayed in the single display screen of the client device, and wherein the image display corresponding to the second split window is not viewable until a scrolling action is received on the client device.

7. The apparatus of claim 6, wherein the processor executes further instructions to cause the second split window to scroll through the content file.

8. The apparatus of claim 7, wherein the processor executes further instructions to cause the second split window automatically scroll to a next portion of the content file when an image of a previous portion of the content file is captured.

9. The apparatus of claim 7, wherein the plurality of different images are captured as the second split window scrolls to the different corresponding portions of the content file.

10. The apparatus of claim 6, wherein the stitched image display collectively provide an image of the entire content file.

11. A non-transitory computer-readable storage medium, having embodied thereon a program executable by a processor to perform a method for using split windows for cross-platform document views, the method comprising:

receiving a request from a client device having a single display screen, the request concerning application display information for content file accessible via an application;

executing the application to access the content file at a host device having a single display screen, wherein execution of the application generates on the single display screen of the host device a split window view of the content file, the split window view comprising at least two split windows, each split window independently providing a view of a portion of the content file;

sending an image of a first split window of the at least two split windows to the client device, wherein the single display screen of the client device displays the image on the client device corresponding to the first split window of the at least two split windows in the single display screen of the host device;

scrolling through the content file via a second split window of the at least two split windows in the single display screen of the host device;

capturing a plurality of different images corresponding to the second split window of the at least two split windows as the second split window in the single display screen of the host device scrolls through the content file, wherein each of the plurality of images corresponds to a different portion of the scrolled content file; and

sending the captured images to the client device, wherein the client device;

stitches the captured images together to generate an image display corresponding to the second split window, and

stitches the image display corresponding to the second split window to the image of the first split window currently displayed in the single display screen of the client device, and wherein the image display corresponding to the second split window is not viewable until a scrolling action is received on the client device.

12. The non-transitory computer-readable storage medium of claim 11, further comprising executable instructions for causing the second split window to scroll through the content file.

13. The non-transitory computer-readable storage medium of claim 12, further comprising executable instructions for causing the second split window to scroll automatically to a next portion of the content file when an image of a previous portion of the content file is captured.

14. The non-transitory computer-readable storage medium of claim 12, wherein the plurality of different images are captured as the second split window scrolls to the different corresponding portions of the content file.

15. The non-transitory computer-readable storage medium of claim 11, wherein the stitched image display collectively provide an image of the entire content file.
