Abstract

Provided are a method of reproducing content using a universal plug and play (UPnP) device which has a plurality of reproduction regions. According to the method, information regarding reproduction regions is obtained using newly defined actions before a control point calls an action “Play( ).” Then, a reproduction region for a piece of content is designated according to a user'"'"'s input. Accordingly, the user can simultaneously enjoy a plurality of pieces of content in desired reproduction regions on a screen of a UPnP device.

Claims

1. A method of controlling a universal plug and play (UPnP) device which has a plurality of reproduction regions on a screen thereof, at a remote control point, the method comprising:

receiving information regarding the reproduction regions from the UPnP device;

selecting one of the reproduction regions according to an input; and

requesting the UPnP device to reproduce content in the reproduction region which is selected.

2. The method of claim 1, further comprising requesting information regarding the reproduction regions by calling an action of a rendering control service (RCS) provided by a media renderer of the UPnP device.

3. The method of claim 1, wherein the information regarding the reproduction regions comprises an extensible markup language (XML) document which comprises descriptive text of the reproduction regions and respective reproduction region identifiers (IDs) of the reproduction regions.

4. The method of claim 2, wherein the requesting comprises transmitting a message informing the media renderer of the UPnP device about the reproduction region, wherein the message is used to call the action of the RCS provided by the media renderer of the UPnP device, and the message comprises a reproduction region ID of the reproduction region and an RCS instance ID for reproduction of the content.

5. A computer readable recording medium having recorded thereon a computer program for executing the method of claim 1.

6. A control point remotely controlling a universal plug and play (UPnP) device which has a plurality of reproduction regions on a screen thereof, the control point comprising:

a reproduction region information reception unit which receives information regarding the reproduction regions from the UPnP device;

a selection unit which selects one of the reproduction regions according to an input; and

a reproduction request unit which requests the UPnP device to reproduce content in the reproduction region which is selected by the selection unit.

7. The control point of claim 6, further comprising a reproduction region information request unit which requests information regarding the reproduction regions by calling an action of a rendering control service (RCS) provided by a media renderer of the UPnP device.

8. The control point of claim 6, wherein the information regarding the reproduction regions comprises an extensible markup language (XML) document which comprises descriptive text of the reproduction regions and respective reproduction region identifiers (IDs) of the reproduction regions.

9. The control point of claim 7, wherein the reproduction region information request unit transmits a message informing the media renderer of the UPnP device about the reproduction region to the UPnP device, wherein the message is used to call the action of the RCS provided by the media renderer of the UPnP device and the message comprises a reproduction region ID of the selected reproduction region and an RCS instance ID for reproduction of the content.

10. A method of reproducing content at a universal plug and play (UPnP) device which has a plurality of reproduction regions on a screen thereof, the method comprising:

transmitting information regarding the reproduction regions to a remote control point;

receiving, from the control point, a request to reproduce content in a reproduction unit of the reproduction regions designated by the control point; and

reproducing the content in the reproduction region designated by the control point.

11. The method of claim 10, further comprising receiving a message requesting the information regarding the reproduction regions from the control point, wherein the message is used to call an action of a rendering control service (RCS) provided by a media renderer of the UPnP device.

12. The method of claim 10, wherein the information regarding the reproduction regions comprises an extensible markup language (XML) document which comprises descriptive text of the reproduction regions and respective reproduction region identifiers (IDs) of the reproduction regions.

13. The method of claim 12, wherein the receiving the request comprises receiving, from the control point, a message for calling the action of the RCS provided by the media renderer of the UPnP device, wherein the message comprises a reproduction region ID of the designated reproduction region and an RCS instance ID for reproduction of the content.

14. A computer readable recording medium having recorded thereon a computer program for executing the method of claim 10.

15. A universal plug and play (UPnP) device having a plurality of reproduction regions on a screen thereof, the device comprising:

a reproduction region information transmission unit which transmits information regarding the reproduction regions to a remote control point;

a reproduction request reception unit which receives, from the control point, a request to reproduce content in a reproduction region of the reproduction regions designated by the control point; and

a content reproduction unit reproducing the content in a reproduction region designated by the control point.

16. The device of claim 15, further comprising a reproduction region request reception unit which receives a message requesting the information regarding the reproduction regions from the control point, wherein the message is used to call an action of an RCS provided by a media renderer of the UPnP device.

17. The device of claim 15, wherein the information regarding the reproduction regions comprises an extensible markup language (XML) document which comprises descriptive text of the reproduction regions and respective reproduction region IDs of the reproduction regions.

18. The device of claim 17, wherein the reproduction request reception unit receives, from the control point, a message for calling the action of the RCS provided by the media renderer of the UPnP device, wherein the message comprises a reproduction region ID of the reproduction region and an RCS instance ID for reproduction of the content.
