Abstract

A three-dimensional (3D) image may be provided in a receiving system by receiving a request for a 3D image viewing while displaying content from a first input source, switching from the first input source to a second input source that correspond to a specific source device, receiving the 3D image transmitted from the specific source device, and displaying the received 3D image at the receiving system.

Claims

1. A method of providing a three-dimensional (3D) image in a receiving system, the method comprising:

receiving a request for a 3D image viewing while displaying content from a first input source at the receiving system;

switching from the first input source to a second input source that correspond to a specific source device;

receiving the 3D image from the specific source device; and

displaying the received 3D image at the receiving system.

2. The method of claim 1, further comprising determining a source device that can provide a 3D image in response to receiving the request.

3. The method of claim 2, wherein determining the source device includes determining whether the source device can provide a 3D image based on a field value within packet content received from the source device.

4. The method of claim 3, wherein the field value is a HDMI Video Format field value, and the packet content is a Vendor Specific InfoFrame packet content.

5. The method of claim 1, further comprising transmitting a play command to the source device.

6. The method of claim 5, wherein the play command is transmitted through a consumer electronics control (CEC) line to the corresponding source device.

7. The method of claim 1, wherein the specific source device is coupled to the receiving system through a digital interface.

8. The method of claim 7, wherein the digital interface is a high definition multimedia interface (HDMI).

9. The method of claim 1, wherein receiving the 3D image includes:

displaying information of a plurality of source devices when there are the plurality of source devices that can provide a 3D image;

switching the input source to the selected source device when one of the displayed information of the plurality of source devices is selected by a user; and

transmitting a play command to the selected source device.

10. The method of claim 1, wherein receiving the 3D image includes:

transmitting a play command while switching the input source for a plurality of source devices at a constant time interval when the plurality of source devices can provide a 3D image.

11. The method of claim 1, wherein when no source device can provide a 3D image, the method further comprises displaying an error message of no executable 3D image.

12. A receiving system to provide a three dimensional (3D) image comprising:

a display to display content; and

a 3D image processor to receive a request for a 3D image viewing while the display displays the content from a first input source, the 3D image processor to switch from the first input source to a second input source that corresponds to a specific source device, the 3D image processor to receive the 3D image transmitted from the specific source device, and the display displays the received 3D image.

13. The receiving system of claim 12, wherein the 3D image processor determines the specific source device that can provide the 3D image in response to receiving the request.

14. The receiving system of claim 12, wherein the 3D image processor determines whether the specific source device can provide the 3D image based on a field value within packet content received from the specific source device.

15. The receiving system of claim 14, wherein the field value is a HDMI Video Format field value, and the packet content is a Vendor Specific InfoFrame packet content.

16. The receiving system of claim 12, wherein the 3D image processor transmits a play command to the specific source device.

17. The receiving system of claim 16, wherein the play command is transmitted through a consumer electronics control (CEC) line to the specific source device.

18. The receiving system of claim 12, further comprising a display interface to couple the specific source device to the receiving system.

19. The receiving system of claim 18, wherein the digital interface is a high definition multimedia interface (HDMI).

20. The receiving system of claim 12, wherein when it is determined that a plurality of source devices can provide a 3D image, the 3D image processor displays information of the plurality of source devices,

wherein the 3D image processor switches the input source to the selected source device when one of the displayed information of the plurality of source devices is selected by a user, and the 3D image processor transmits a play command to the selected source device.

21. The receiving system of claim 12, wherein the 3D image processor transmits a play command while switching the input source for the plurality of source devices at a constant time interval when the plurality of source devices can provide a 3D image.

22. The receiving system of claim 12, wherein the display displays an error message of no executable 3D image when no source device can provide a 3D image.

23. A method comprising:

receiving a request for a three-dimensional (3D) image viewing while displaying content from an input source;

determining whether any source device can provide a 3D image in response to receiving the request; and

displaying, in response to the determining, information that no source device can currently provide a 3D image.

24. The method of claim 23, wherein determining the source device includes determining whether the source device can provide a 3D image based on a field value within packet content received from the source device.

25. The method of claim 24, wherein the field value is a HDMI Video Format field value, and the packet content is a Vendor Specific InfoFrame packet content.

26. The method of claim 23, further comprising transmitting a play command to the source device.
