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;

searching source devices that can provide 3D images in response to receiving the request for the 3D image viewing, each source device being coupled to the receiving system through a high definition multimedia interface (HDMI),

wherein searching source devices includes;

receiving a Vendor Specific InfoFrame packet content from the specific source device; and

determining whether the specific source device can provide a 3D image based on a value of an HDMI Video Format field in the Vendor Specific InfoFrame packet content;

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

switching an input mode to a source device, which is selected by a user based on the displayed information, from among the plurality of source devices;

identifying a transport format of a 3D image of the selected source device based on a value of a 3D Structure field in the Vendor Specific InfoFrame packet content received from the selected source device;

receiving the 3D image from the selected source device;

decoding the received 3D image in accordance with the identified transport format; and

displaying the decoded 3D image at the receiving system.

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

3. The method of claim 2, wherein the play command is transmitted through a consumer electronics control (CEC) line to the selected source device.

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

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

5. 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.

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

a display configured to display a content; and

a 3D image processor configured to receive a request for a 3D image viewing, to search source devices that can provide 3D images by receiving a Vendor Specific InfoFrame packet content from each source device and determining whether the source device can provide a 3D image based on a value of an HDMI Video Format field in the Vendor Specific InfoFrame packet content to display information of a plurality of source devices when there are the plurality of source devices to switch an input mode to a source device, which is selected by a user based on the displayed information, from among the plurality of source devices, to identify a transport format of a 3D image of the selected source device based on a value of a 3D Structure field in the Vendor Specific InfoFrame packet content received from the selected source device, to receive the 3D image from the selected source device, and to decode the received 3D image in accordance with the identified transport format,

wherein the display displays the decoded 3D image, and wherein each source device is coupled to the receiving system through a high definition multimedia interface (HDMI).

7. The receiving system of claim 6, wherein the 3D image processor transmits a play command to the selected source device.

8. The receiving system of claim 7, wherein the play command is transmitted through a consumer electronics control (CEC) line to the selected source device.

9. The receiving system of claim 6, wherein the 3D image processor transmits a play command while switching the input mode for the plurality of source devices at a constant time interval when the plurality of source devices can provide the 3D images.

10. The receiving system of claim 6, wherein the display displays an error message of no executable 3D image when no source device can provide a 3D image.
