Abstract

The present invention relates to a method and a web engine. According to a first aspect of the present invention a web engine configured for an ITF (IPTV Terminal Function) such as a STB (set-top-box) comprising an application framework associated with an API enabling display of applications is provided. The application framework comprises a memory for storing at least two applications, wherein the applications are arranged in a hierarchical tree structure in relation to each other. The application framework further comprises an application manager comprising a receiving unit for receiving the event, e.g. a key press, and a controller for controlling the dispatching. The controller may comprise an event wrapper for wrapping and unwrapping the event and a dispatcher for transferring the wrapped event down through the application tree. For each application node (also the root node) the application manager is configured to determine if an event should be processed by the current application.

Claims

1. A method in a web engine configured for an IPTV Terminal Function comprising an application framework associated with an Application Programming Interface enabling display of applications, the method comprising:

storing at least two applications, wherein the applications are arranged in a hierarchical tree structure in relation to each other,

receiving an event targeting at least one application, and

controlling dispatching of the received event targeting at least one application, wherein the controlling further comprises dispatching the received event to a target application,

determining for each application if the event should be processed by the current application and if it should be processed, then the method comprises processing the event for the current application and if it should not be processed then the method comprises dispatching the event to a subsequent application in the hierarchical tree structure.

2. The method according to claim 1, wherein the controlling further comprises wrapping the event before the dispatching and wherein the event is unwrapped before the processing.

3. The method according to claim 1, wherein determining for each application, if the event should be processed by the current application is performed by inspecting the event and checking if the event is applicable on the current application.

4. The method according to claim 1, wherein determining for each application, if the event should be processed by the current application is performed by the application manager.

5. The method according to claim 1, wherein the application framework is configured to use a Document Object Model, DOM, based model for structuring the applications.

6. The method according to claim 1, wherein the ITF is any of a set-top-box, mobile terminal, or a PC.

7. An IPTV terminal implementing an application framework enabling display of web applications on a display device, said application framework comprising:

memory to store two or more applications organized in a hierarchical tree structure; and

an application manager to receive events targeting one of said applications in said hierarchical tree structure, said application manager comprising;

a controller to determine whether a first application in said hierarchical tree structure is the targeted application, and

a dispatcher to dispatch the event to a second application in said hierarchical tree structure if the first application is not the targeted application.

8. The computing device of claim 7 wherein the application manger further comprises an event wrapper to for wrapping and unwrapping events.

9. The computing device of claim 7 wherein the controller stores information indicating the target application for the event.

10. The computing device of claim 7 wherein the application framework uses a Document Object Model (DOM) based model for organizing the applications.

11. The computing device of claim 7 incorporated in a set-top box, mobile terminal, or personal computer.
