Abstract

The present invention relates to an add-on architecture which can be applied to a network device. A network device for processing at least one or more applications, according to one embodiment of the present invention, comprises: a host S/W processing module which receives a key event for executing a specific command, and transmits the received key event to an add-on system manager, said add-on system manager which checks a focused specific application from among one or more applications currently being executed, and which transmits the received key event to the focused specific application; and an add-on application which processes the received key event.

Claims

1. In a network device processing at least one or more applications, the network device processing at least one or more applications comprising:

a host S/W processing module configured to receive a key-event for executing a specific command and to optionally transmit the received key-event to an add-on system manager;

an add-on system manager configured to verify a specific application that is focused among at least one or more currently executable applications, and to transmit the received key-event to the focused specific application; and

an add-on application configured to process the received key-event.

2. The network device of claim 1, wherein, when the host S/W processing module receives the key-event, the host S/W processing module determines whether or not the received key-event is to be processed only by the host S/W processing module, and wherein, based upon the determined result, if the received key-event is determined to be processed only by the host S/W processing module, the host S/W processing module processes the key-event by itself.

3. The network device of claim 1, wherein the add-on system manager comprises:

an application browser configured to show a list of add-on applications installed in the network device;

an application controller configured to execute applications that are requested to be executed, and to register and manage a process of the executed application;

an application downloader configured to download, install, and delete an add-on application; and

a security checker checking for any damage occurring in the downloaded or installed add-on application.

4. The network device of claim 1, wherein the host S/W module comprises:

a host agent configured to transmit a status of the host S/W module and a key-event to an add-on manager; and

an open API host configured to execute an open API call on an add-on application and to return the respective result.

5. The network device of claim 1, wherein the add-on application comprises:

an add-on agent configured to transmit a status of the add-on application to add-on manager and to receive a key-event; and

an open API configured to provide an API required for designing the add-on application.

6. The network device of claim 3, wherein the application controller executes an application by using a method of performing at least one or more of an automatic execution by using metadata, when an application or content is distributed, an execution of an application that is signaled at a specific point of a content, an execution initiated by triggering, an execution initiated by calling another application within an application, and an execution initiated by a user'"'"'s application execution selection.

7. The network device of claim 3, wherein the application controller remembers a status prior to the execution of the add-on application, and, wherein, when the add-on application is ended by an abnormal termination, the application controller recovers the system to the remembered status.

8. (canceled)

9. (canceled)

10. In a method for controlling a network device processing at least one or more applications, the method for controlling the network device processing at least one or more applications comprising:

transmitting a signal requesting for an authentication of the network device to a server;

receiving an identification signal identifying a confirmed authentication or a non-confirmed authentication of the network device from the server;

when the identification signal corresponds to a signal confirming the authentication of the network device, downloading an application from the server;

receiving a specific key-event for executing a specific command, and optionally transmitting the received key-event to an add-on system manager; and

verifying a focused specific application, among at least one or more of currently executable applications, and transmitting the received key-event to the focused specific application.

11. (canceled)

12. In a method for controlling a network device processing at least one or more applications, the method for controlling the network device processing at least one or more applications comprising:

transmitting a signal requesting a first list for identifying at least one or more downloadable applications or requesting a second list for identifying at least one or more downloadable contents to a server;

receiving the first list or the second list from the server;

displaying the received first list or second list;

when a specific application is selected from the first list, or when a specific content is selected from the second list, transmitting a signal requesting the selected application or content to the server; and

downloading the selected application or content from the server.

13. The method of claim 12, wherein the step of displaying the first list further comprises:

checking system requirements of the network device receiving the first list; and

marking only applications that can be executed by the network device based upon the checked information.

14. The method of claim 12, wherein the step of displaying the second list further comprises:

searching for applications that are already installed in the network device receiving the second list; and

marking only the contents that can be applied by the searched application.

15. The method of claim 12, wherein the step of requesting a first list or a second list, further comprises:

setting-up at least one or more filtering options.

16. The method of claim 12, wherein the filtering options includes at least one or more of an application title, a number of downloads, a number of recommendations, and a registration date.

17. (canceled)

18. In a method for controlling a network device processing at least one or more applications, the method for controlling the network device processing at least one or more applications comprising:

receiving a key-event for creating an applications list;

searching for an application that is already installed in the network device;

creating a list of the searched applications;

displaying the created applications list;

receiving an execution request on an application selected from the at least one or more applications listed in the applications list;

verifying whether or not the application requested to be executed can be executed normally by using metadata of the corresponding application; and

when it is verified that the corresponding application can be executed normally, executing the corresponding application.

19. The method of claim 18, wherein, the step of creating a list of the searched applications further comprises:

searching for contents already stored in the network device; and

creating a sub list respective to contents applicable by the corresponding applications, among the searched contents.
