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:

sending a request concerning application display information from a client device having a single display screen to a host device having a single display screen, wherein the host device is hosting an application capable of providing a split window view of a single content file, wherein the host device executes the application to generate on the single display screen of the host device the split window view comprising at least two split windows, and wherein each split window of the host device independently providing a view of a portion of the same content file;

receiving information sent over the communication network from the host device, the information including display information regarding the at least two split windows generated by the application on the host device, wherein the received information regarding a first split window comprises an image of a first portion of the content file in a view provided by the first split window on the host device, and wherein the received information regarding a second split window comprises a plurality of images pertaining to a plurality of different portions of the same content file;

generating an image on the single display screen on the client device, wherein the client device single display screen provides a single screen view corresponding to the first split window of the at least two split windows of the host device; and

processing the display information regarding the second split window of the at least two split windows of the host device, wherein an image corresponding to the second split window is stitched to the image display corresponding to the first split window and wherein the image display corresponding to the second split window is not viewable until a scrolling action is received on the single display screen of the client device.

2. The method of claim 1, wherein the first split window and the second split window of the host device display different parts of the same content file.

3. The method of claim 1, wherein the received information comprises a plurality of images.

4. The method of claim 1, wherein the received information regarding the first split window comprises an image of a first portion of the content file in a view provided by the first split window on the host device.

5. The method of claim 1, further comprising continuing to receive the plurality of images corresponding to the second split window and processing in the background the received plurality of images, wherein the processed plurality of images are not immediately displayed at the client device.

6. The method of claim 1, wherein a first image of the plurality of images corresponds to a portion immediately subsequent to a portion displayed in the first split window, and wherein a next image of the plurality of images corresponds to a next immediately subsequent portion.

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

a communication interface that;

sends a request concerning application display information from a client device having a single display screen to a host device having a single display screen, wherein the host device is hosting an application capable of providing a split window view of a single content file, wherein the host device executes the application to generate on a single display screen of the host device the split window view comprising at least two split windows, and wherein each split window of the host device independently providing a view of a portion of the same content file, and

receives information sent over the communication network from the host device, the information including display information regarding the at least two split windows generated by the application on the host device, wherein the received information regarding a first split window comprises an image of a first portion of the content file in a view provided by the first split window on the host device, and wherein the received information regarding a second split window comprises a plurality of images pertaining to a plurality of different portions of the same content file;

the single display screen of the client device that displays an image, wherein the client device single display screen provides a single screen view corresponding to the first split window of the at least two split windows;

a processor of the client device that executes instructions stored in memory, wherein execution of the instructions by the processor processes the display information regarding the second split window of the at least two split windows, wherein an image corresponding to the second split window is stitched to the image display corresponding to the first split window, and a user interface of the client device that allows for scrolling of the display of the single display screen of the client device, wherein the image display corresponding to the second split window is not viewable until a scrolling action is received.

8. The apparatus of claim 7, wherein the first split window and the second split window of the host device display different parts of the same content file.

9. The apparatus of claim 7, wherein the received information comprises a plurality of images.

10. The apparatus of claim 7, wherein the plurality of images corresponding to the second split window are captured as the host device scrolls through the view provided by the second split window.

11. The apparatus of claim 7, further comprising continuing to receive the plurality of images corresponding to the second split window and processing in the background the received plurality of images, wherein the processed plurality of images are not immediately displayed at the client device.

12. The apparatus of claim 7, wherein a first image of the plurality of images corresponds to a portion immediately subsequent to a portion displayed in the first split window, and wherein a next image of the plurality of images corresponds to a next immediately subsequent portion.

13. 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:

sending a request concerning application display information to a host device, wherein the host device is hosting an application capable of providing a split window view of a single content file, wherein the host device executes the application to generate on a single display screen of the host device the split window view comprising at least two split windows, and wherein each split window of the host device independently providing a view of a portion of the same content file;

receiving information from the host device, the information including display information regarding the at least two split windows generated by the application on the host device, wherein the received information regarding a first split window comprises an image of a first portion of the content file in a view provided by the first split window on the host device, and wherein the received information regarding a second split window comprises a plurality of images pertaining to a plurality of different portions of the same content file;

generating an image on a single display screen, wherein the single display screen provides a single screen view corresponding to the first split window of the at least two split windows; and

processing the display information regarding the second split window of the at least two split windows, wherein an image corresponding to the second split window is stitched to the image display corresponding to the first split window and wherein the image on the single display screen corresponding to the second split window is not viewable until a scrolling action is received.
