Abstract

In a method for sharing multimedia application data by a plurality of communication devices, at least two communication devices establish a short-rang wireless communication link to a data distribution device. At least one of the communication devices informs the data distribution device of the data that are offered for sharing, and these data are presented by the data distribution device on a display. A user of one of the communication devices being connected to the data distribution device selects and requests data that he wants to download to a communication device, and the requested data are then transmitted to the communication device via the data distribution device.

Claims

1. A method for sharing multimedia application data by a plurality of communication devices, the method comprising:

a) establishing respective short-range wireless communication links from a plurality of communication devices to a data distribution device;

b) informing the data distribution device of data that are offered for sharing by at least one of the plurality of communication devices;

c) presenting on a display, by the data distribution device, an indication of the data offered for sharing by the at least one communication device;

d) transmitting an information request from a second of the plurality of communication devices to the data distribution device, the information request identifying data that are requested for download to the second communication device; and

e) transmitting the requested data to the second communication device via the data distribution device.

2. The method of claim 1, wherein informing the data distribution device of the data that are offered for sharing comprises transmitting the data that are offered for sharing to the data distribution device and storing the data that are offered for sharing at the data distribution device.

3. The method of claim 2, wherein transmitting the requested data to the second communication device via the data distribution device comprises transmitting the requested data directly to the second communication device from the data distribution device.

4. The method of claim 3, wherein the data stored by the data distribution device are deleted if the communication link between the data distribution device and the at least one communication device is terminated.

5. The method of claim 3, wherein the data distribution device keeps the stored data if the communication link between the data distribution device and the at least one communication device is terminated.

6. The method of claim 1, wherein informing the data distribution device of the data that are offered for sharing by the at least one communication device comprises transmitting information about the content of the data that are offered for sharing from the at least one communication device to the data distribution device;

and

wherein, in transmitting the requested data to the second communication device via the data distribution device, the data are at first transmitted from the at least one communication device to the data distribution device, and are forwarded to the second communication device.

7. The method of claim 1, further comprising graphically displaying at the second communication device a selection corresponding to the data that are offered for sharing, and selecting data requested for download from among the data that are offered for sharing.

8. The method of claim 1, wherein data that have been requested by at least one of the communication devices are graphically indicated on the display.

9. The method of claim 1, wherein the communication links established between the communication devices and the data distribution device comprise a Bluetooth link.

10. The method of claim 1, wherein the data that are offered for sharing comprise digital pictures.

11. The method of claim 10, wherein the pictures offered for sharing are presented as thumbnails on the display by the data distribution device.

12. The method of claim 11, wherein a plurality of the thumbnails are simultaneously shown on the display.

13. The method of claim 11, wherein the thumbnails are successively shown on the display.

14. The method of claim 13, wherein the thumbnails are shown on the displays of the communication devices.

15. The method of claim 10, wherein the pictures offered for sharing are shown successively on the display.

16. A system for sharing multimedia application data, comprising:

a data distribution device and at least two communication devices that are connected to the data distribution device via respective short-range wireless communication links;

wherein the data distribution device is configured to;

a) receive information from at least one of the communication devices relative to data that are offered for sharing by the at least one communication device;

b) present the data that are offered by the at least one communication device for sharing on a display;

c) receive an information request from a second of the communication devices, the information request identifying the data that are requested for downloading by the second communication device; and

d) transmit the requested data to the second communication device.
