Abstract

Methods of operating a portable electronic device including a display screen, a user interface, a controller, a memory and a transceiver are provided. The methods include executing a resource on the controller, and receiving a snapshot command through the user interface. In response to the snapshot command, a network address of a remote server from which the resource was downloaded is obtained, an audiovisual signal representative of the resource is generated, and the audiovisual signal and the network address are stored in a file. The file can be forwarded using the transceiver to a remote terminal, which can access the resource from the network address.

Claims

1. A method of operating a portable electronic device including a display screen, a user interface, a controller, a memory and a transceiver, the method comprising:

executing a resource on the controller;

receiving a snapshot command through the user interface; and

in response to the snapshot command;

determining a network address of a remote server from which the resource was downloaded;

generating an audiovisual signal representative of the resource; and

storing the audiovisual signal and the network address in a file.

2. The method of claim 1, wherein determining the network address comprises determining a uniform resource indicator (URI) associated with the remote server.

3. The method of claim 2, wherein determining the network address comprises retrieving a URI from a table of URI entries associated with resources stored in the portable electronic device and/or retrieving the URI from the resource.

4. The method of claim 1, wherein storing the audiovisual signal with the network address comprises generating Exif metadata including the network address and associating the Exif metadata with the audiovisual signal in the file.

5. The method of claim 1, further comprising:

receiving a forward command through the user interface; and

in response to the forward command, transmitting the file to a remote terminal using the transceiver.

6. The method of claim 1, further comprising:

downloading the application program from the remote server using the transceiver,

storing the network address of the remote server; and

associating the network address of the remote server with the resource.

7. The method of claim 6, further comprising:

generating a database including associations of resources stored on the electronic device with network addresses of remote servers from which the respective resources were downloaded.

8. The method of claim 1, wherein the resource comprises an application program, executing the resource on the controller comprises executing the application program on the controller, and generating the audiovisual signal representative of the resource comprises storing a copy of an audiovisual content generated by the application program.

9. The method of claim 8, wherein the audiovisual content generated by the application program comprises a display image generated by the application program, and/or an audio signal generated by the application program.

10. The method of claim 9, wherein the display image generated by the application program comprises a still image and/or a video image.

11. The method of claim 1, wherein the resource comprises an audiovisual file, and wherein generating an audiovisual signal representative of the resource comprises generating a truncated and/or reduced version of the resource.

12. The method of claim 1, wherein generating the audiovisual signal representative of the resource comprises saving a screenshot of an image on the display screen.

13. The method of claim 1, further comprising determining an identity of an active resource at the time of the snapshot command, wherein the identity of the resource is determined as the identity of the active resource.

14. A portable electronic device, comprising:

a display screen configured to display still and/or video images;

a user interface configured to receive a user input;

a transceiver configured to establish a wireless communications link with a remote server and to download a resource from the remote server; and

a controller configured to execute the resource, to receive a snapshot command through the user interface during execution of the resource, and in response to the snapshot command, to determine a network address of the remote server and to store a snapshot of the resource and the network address in a file.

15. The portable electronic device of claim 14, the controller is configured to determine the network address by retrieving a uniform resource indicator (URI) from a table of UPI entries associated with resources stored in the portable electronic device.

16. The portable electronic device of claim 14, wherein the snapshot of the resource comprises an image displayed on the display screen, and the controller is configured to generate metadata including the network address and to include the metadata along with the snapshot in the file.

17. The portable electronic device of claim 14, wherein the controller is further configured to receive a forward command through the user interface, and in response to the forward command, to transmit the file including the snapshot and the network address to a remote terminal using the transceiver.

18. The portable electronic device of claim 14, wherein the controller is further configured to store the network address of the remote server in a database, and to associate the network address with the resource in the database.

19. A system, comprising:

a provisioning server that stores a resource and that makes the resource available for downloading by remote terminals; and

a portable electronic device, comprising;

a display screen configured to display still and/or video images;

a user interface configured to receive a user input;

a transceiver configured to establish a wireless communications link with the provisioning server and to download the resource from the provisioning server; and

a controller configured to execute the resource, to receive a snapshot command through the user interface during execution of the resource, and in response to the snapshot command, to determine a network address associated with the provisioning server and to store a snapshot of the resource and the network address in a file.

20. The system of claim 19, wherein the controller of the portable electronic device is further configured to receive a forward command through the user interface, and in response to the forward command, to transmit the file including the snapshot and the network address to a remote terminal using the transceiver.
