The following specification particularly describes the invention and the manner in which it is to be performed :

AUTOMATIC SWITCH OF SCREEN LAYOUTS
Field of the Disclosure: -
The present disclosure relates to automatic switch of screen layouts and more particularly, but not limited to, automatic switch of screen layouts on video walls.
Background: -
There are several display options currently available, which are capable of displaying higher capacity of information. Popular displays are such as video walls and huge LED screens, which display specific information on screen layouts where the specific information relates to the industry they are being used in. For e.g. in a Network Operation Center (NOC), a video wall is used to display various network related information, performance statistics, maps, real time major and critical events in the form of Dashboards which helps engineers in the NOC take quick actions in case of emergency situations and therefore, results in easier monitoring.
However, there are several limitations associated with aforementioned displays such as restricted space for multiple display, therefore only limited information is visible and only one screen layout is visible at all times.
Conventionally known art offers a solution to such limitations, wherein screen layouts are switched and displayed. However, such switch of screen layouts requires a server for each screen layout and corresponding hardware. So, if we have three screen layouts to be displayed, we require three servers and their respective peripherals for such switching to take place. Additional hardware as required makes implementation of conventional art costly and cumbersome, owing to the greater amount of equipment involved.

Further, there is a time delay between display of each screen layout in conventional art. In addition, there is no check regarding the suitability of display of a screen layout. Even if a screen layout is not suitable for display, it is displayed by the conventional art, which results in an undesired blank screen on the video wall.

Figure 1 illustrates a method for automatic switch of screen layouts in accordance with an embodiment of the present disclosure. Object information for each screen layout is acquired 101 and processed as per user requirements 102. Object information according to an example of the embodiment refers to handler content of an application in the DLL (Dynamic Link Library), where the application is being displayed on the screen layout. User requirements according to an example of the embodiment refer to specifying display time of each screen layout and prioritizing each screen layout by the user himself. The processed object information is then stored in a data storage array 103 where according to an example of the embodiment, the data storage array is an array list. When a screen layout is to be displayed, its suitability for display is first evaluated 104 and then the screen layouts are displayed and automatically switched as per evaluation and stored object information 105.
According to an embodiment of the disclosure, displaying and automatically switching screen layouts comprises automatically skipping display of a screen layout which is not suitable for display. In an example of the embodiment, not suitable for display is such as application running on screen layout is hung and application running on screen layout is refreshing.
Figure 2 teaches a system for automatic switch of screen layouts according to an embodiment of the present disclosure. The system comprises an acquisition unit

201, a processor 202 coupled to the acquisition unit, a data storage array 203 coupled to the processor, and evaluation unit 204 coupled to the data storage array and a display interface 205 coupled to the evaluation unit.
The acquisition unit 201 is configured to acquire object information for each screen layout. According to an example of the embodiment, the object information is handler content of an application in the DLL (Dynamic Link Library), where the application is being displayed on the screen layout. According to an embodiment, the processor 202 is configured to process the acquired object information as per user requirements such as display time of each screen layout and priority of each screen layout. The processed object information is then stored in the data storage array 203 where according to an example of the embodiment, the data storage array is an array list. The evaluation unit 204 is configured to evaluate suitability of a screen layout for display. Upon evaluation, the evaluation unit retrieves the object information of the screen layout from the data storage array 203 and forwards it along with its evaluation to the display interface 205. The display interface 205 is configured to display and automatically switch screen layouts as per output of the evaluation unit and stored object information. According to an embodiment of the disclosure, the display interface 205 is configured to automatically skip display of a screen layout, which is not suitable for display. As an example, not suitable for display is such as application running on screen layout is hung and application running on screen layout is refreshing.
For e.g. if a screen layout is for an application which is refreshing, the display interface would skip that screen layout altogether instead of displaying a blank screen and move to the next screen layout.
Example of an Embodiment

Figure 3 illustrates a system for automatic switch of screen layouts according to an example of the embodiment of the present disclosure. The example pertains to a video wall, which is used to display information. The system comprises a server 301, which comprises the applications being run and displayed on screen layouts. For better illustrations, according to another example, the applications running on the server 301 are a Flash presentation, a PDF document and Internet explorer. The acquisition unit 302, is configured to acquire the object information of each screen layout wherein the applications are running. According to an example, the object information is handler content of each an application in the DLL (Dynamic Link Library). Therefore, the acquisition unit acquires handler content for Flash, PDF as well as the Internet explorer.
The acquired handler content is then processed by a processor 303 wherein the processor comprises a timer 303a. A user is equipped to program the timer according to his preference and the object information is accordingly processed and stored in an array list 304. According to yet another example, the user specifies through the timer that all screen layouts are to be displayed for 2 minutes each. Accordingly, the Flash presentation, the PDF document and the Internet explorer are displayed for 2 minutes each and automatically switched to the next screen layout.
When an application runs, the screen layout is to be displayed on the display interface which according to the example is a video wall 305. However, the screen layouts are first evaluated for their suitability for display by an evaluation unit 304. Upon evaluation, the evaluation unit 304 retrieves the object information of the screen layout from the array list 303 and forwards it along with its evaluation to the video wall 305.
The video wall 305 is configured to display and automatically switch screen layouts as per output of the evaluation unit and stored object information.

According to an embodiment of the disclosure, the video wall 305 is configured to automatically skip display of a screen layout, which is not suitable for display. As an example, not suitable for display is such as application running on screen layout is hung and application running on screen layout is refreshing.
Therefore, according to the example, Flash presentation is first displayed on the video wall 305, after 2 minutes, the screen layout automatically switches and the PDF document is displayed. After another 2 minutes, the screen layout automatically switches and the internet explorer is displayed. If the internet explorer is refreshing when it is to be displayed, the evaluation unit identifies its status and accordingly the video wall automatically skips the internet explorer screen layout and automatically switches to the Flash presentation.
According to another example of the embodiment, during processing of the handler content, the user also specifies priority of each screen layout displaying an application along with setting the timer for 2 minutes. PDF document gets the highest priority, then Internet Explorer and then the Flash presentation. Then during display of screen layouts on the video wall 305, the PDF document is displayed first, after 2 minutes, automatically the Internet Explorer is displayed and after another 2 minutes, the screen layout automatically switches to the Flash presentation.
A person skilled in the art would appreciate that the examples of applications taken are only for illustrations and descriptive purposes. The present disclosure, is not limited to the same.
As per the embodiments and examples of the embodiments described above, the present disclosure requires only one server for display of screen layouts as opposed to the conventional art where each screen layout requires a separate server for each application. Accordingly, the present disclosure ensures lower

cost and lesser hardware requirement for the execution of display of screen layouts.
Further, owing to storage of object information in the data storage array and its consequent retrieval during display of the screen layouts, time delay involved in automatic switching of screen layouts is considerably lowered. In addition, due to the automatic skip of screen layouts not suitable for display, the present disclosure offers seamless and efficient switching of screen layouts.
Embodiments of the present disclosure are applicable to, but not limited, to all genres of industry which involve display of information such as TV studios, museums, art galleries, clubs, theme parks, corporate displays, NOC network operation centers, military command centers, security monitoring centers etc. The embodiments are also applicable to huge LED screens which are another popular display used.
