Abstract

Transmitting and receiving 3D video content via an Internet protocol (IP) stream are described. 3D video content may be transmitted in a single IP stream and adjusted by a device associated with a display for rendering the 3D video content in a desired manner. 3D content also may be transmitted in a plurality of IP streams and a device associated with a display for rendering the 3D content may determine which of the plurality of IP streams to decode based upon a mode of operation of the device. A device receiving 3D video content may be configured to adjust the appearance of the content displayed on a display associated with the device. Such adjusting of the appearance may include moving the position of the rendered 3D video content within the display, positioning in band and/or out of band content in front of, behind, or within the rendered 3D video content.

Claims

1. A method comprising:

determining, based on a characteristic associated with an output device, a first format of multidimensional content, wherein the first format is associated with a first manner in which a first component of the multidimensional content is output relative to a second component of the multidimensional content;

determining, based on the first format, a first stream of a plurality of streams; and

causing the output device to output, based on the first stream, the multidimensional content.

2. The method of claim 1, wherein each of the plurality of streams comprises a different format of the multidimensional content.

3. The method of claim 1, wherein the determining, based on the first format, the first stream comprises determining which of the plurality of streams comprises the first format.

4. The method of claim 1, wherein the characteristic comprises a type of the output device.

5. The method of claim 1, wherein the characteristic is associated with a mode of operation of the output device.

6. The method of claim 1, further comprising determining, based on the first format, a second stream of the plurality of streams, wherein the causing the output device to output the multidimensional content comprises causing the output device to output the first component based on the first stream and the second component based on the second stream.

7. The method of claim 1, further comprising determining, based on a user request, a second format of the multidimensional content, wherein the second format is associated with a second manner in which the first component is output relative to the second component;

determining, based on the second format, a second stream of the plurality of streams; and

causing the output device to switch from the first stream to the second stream to output, based on the second stream, the multidimensional content.

8. The method of claim 1, wherein the first component comprises one of a left video component or a right video component, and the second component comprises the other of the left video component or the right video component.

9. The method of claim 1, wherein the first format is associated with a type of device connected with the output device.

10. A method comprising:

determining, based on a first request associated with an output device, a first format of multidimensional content, wherein the first format is associated with a first manner in which a first component of the multidimensional content is output relative to a second component of the multidimensional content;

determining, based on the first format, a first stream of a plurality of streams; and

sending, to the output device, the first stream.

11. The method of claim 10, wherein the determining, based on the first format, the first stream comprises determining which of the plurality of streams comprises the first format.

12. The method of claim 10, further comprising determining, based on the first request, a second stream of the plurality of streams, wherein first stream comprises the first component and the second stream comprises the second component;

and

sending, to the output device, the second stream in addition to the first stream.

13. The method of claim 10, further comprising determining, based on a second request, a second format of the multidimensional content, wherein the second format is associated with a second manner in which the first component is output relative to the second component;

determining, based on the second format, a second stream of the plurality of streams; and

sending, to the output device, the second stream.

14. The method of claim 10, wherein the first component comprises one of a left video component or a right video component, and the second component comprises the other of the left video component or the right video component.

15. The method of claim 10, further comprising encoding, based on a plurality of formats comprising the first format, the multidimensional content, to generate the plurality of streams comprising the first stream.

16. A method comprising:

determining, based on a first mode of operation of an output device, a first one or more streams comprising two components of multidimensional content, wherein the first one or more streams are associated with a first manner in which the two components are output relative to one another;

causing the two components of the first one or more streams to be output via the output device and in accordance with the first mode of operation;

receiving an indication associated with a second mode of operation of the output device;

determining, based on the indication, a second one or more streams comprising two components of multidimensional content, wherein the second one or more streams are associated with a second manner in which the two components of the second one or more streams are output relative to one another; and

causing the two components of the second one or more streams to be output via the output device and in accordance with the second mode of operation.

17. The method of claim 16, wherein the indication comprises a user request initiated using a user interface output via the output device.

18. The method of claim 16, wherein the indication is based on a requested multimedia format.

19. The method of claim 16, wherein the two components of multidimensional content of the first one or more streams comprise a left video component and a right video component.

20. The method of claim 16, wherein the first mode of operation is associated with a first device being connected with the output device and the second mode of operation is associated with a second device being connected with the output device.
