Abstract

A stereoscopic production solution, e.g., for live events, that provides 3D video asset distribution to multiple devices and networks is described. In some embodiments, live or recorded 3D video content may be accessible by different service providers with different subscribers/users and protocols across a network of the content provider. A first video signal corresponding to a first video feed for one eye of a viewer may be received and a second video signal corresponding to a second video feed for the second eye of the viewer may be received. The first video signal and the second video signal may be encoded. The encoded first video signal and the encoded second video signal may be transmitted independently over a network. The two video signals may be received and frame synced at an off-site location for eventual rendering to a display device.

First claim

What is claimed is:

1. A method comprising:
receiving, by a computing device, a first Internet Protocol (IP) stream comprising a first video component of multidimensional content, wherein the first IP stream does not comprise audio;
receiving a second IP stream comprising a second video component of the multidimensional content and comprising audio;
synchronizing the first video component received via the first IP stream with the second video component received via the second IP stream, comprising generating a frame synchronized video signal comprising the first video component and the second video component;
generating a first video content stream comprising the frame synchronized video signal in a first encoding format;
generating a second video content stream comprising the frame synchronized video signal in a second encoding format; and
causing synchronized output of the first video component received via the first IP stream, the second video component received via the second IP stream, and the audio received via the second IP stream.

2. The method of claim 1 , wherein the synchronized output comprises a first audio-video signal encoded in a first format and a second audio-video signal encoded in a second format, wherein the first audio-video signal in the first format is synchronized with the second audio-video signal in the second format.

3. The method of claim 1 , wherein the causing synchronized output of the first video component, the second video component, and the audio comprises transmitting a single encapsulated IP stream comprising the first video component, the second video component, and the audio.

4. The method of claim 1 , wherein the first IP stream comprises a first encapsulated IP stream, and wherein the second IP stream comprises a second encapsulated IP stream.

5. The method of claim 1 , wherein the synchronizing comprises comparing:
a first plurality of time codes, associated with the first video component, and
a second plurality of time codes, associated with the second video component.

6. The method of claim 1 , wherein the causing the synchronized output comprises outputting, via a stereoscopic display device, the first video component and the second video component.

7. The method of claim 1 , wherein the causing the synchronized output comprises transmitting, to a device separate from the computing device, the first video component and the second video component.

8. The method of claim 1 , wherein the causing the synchronized output comprises transmitting the first video component via a third IP stream and transmitting the second video component via a fourth IP stream.

9. The method of claim 1 , wherein the causing the synchronized output comprises multicasting, using a format that is based on a device separate from the computing device, and to a plurality of destinations, the first video component and the second video component.

10. The method of claim 1 , wherein the first video component comprises a left eye view of the multidimensional content and the second video component comprises a right eye view of the multidimensional content.

11. An apparatus comprising:
one or more processors: and
memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
receive a first Internet Protocol (IP) stream comprising a first video component of multidimensional content, wherein the first IP stream does not comprise audio;
receive a second IP stream comprising a second video component of the multidimensional content and comprising audio;
synchronize the first video component received via the first IP stream with the second video component received via the second IP stream, comprising generating a frame synchronized video signal comprising the first video component and the second video component;
generate a first video content stream comprising the frame synchronized video signal in a first encoding format;
generate a second video content stream comprising the frame synchronized video signal in a second encoding format; and
cause synchronized output of the first video component received via the first IP stream, the second video component received via the second IP stream, and the audio received via the second IP stream.

12. The apparatus of claim 11 , wherein the synchronized output comprises a first audio-video signal encoded in a first format and a second audio-video signal encoded in a second format, wherein the first audio-video signal in the first format is synchronized with the second audio-video signal in the second format.

13. The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, cause the apparatus to cause the synchronized output by at least transmitting a single encapsulated IP stream comprising the first video component, the second video component, and the audio.

14. The apparatus of claim 11 , wherein the first IP stream comprises a first encapsulated IP stream, and wherein the second IP stream comprises a second encapsulated IP stream.

15. The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, cause the apparatus to synchronize by at least comparing:
a first plurality of time codes, associated with the first video component, and
a second plurality of time codes, associated with the second video component.

16. The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, cause the apparatus to cause the synchronized output by at least outputting, via a stereoscopic display device, the first video component and the second video component.

17. The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, cause the apparatus to cause the synchronized output by at least transmitting, to a device separate from the apparatus, the first video component and the second video component.

18. The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, cause the apparatus to cause the synchronized output by at least transmitting the first video component via a third IP stream and transmitting the second video component via a fourth IP stream.

19. The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, cause the apparatus to cause the synchronized output by at least multicasting, using a format that is based on a device separate from the apparatus, and to a plurality of destinations, the first video component and the second video component.

20. The apparatus of claim 11 , wherein the first video component comprises a left eye view of the multidimensional content and the second video component comprises a right eye view of the multidimensional content.

21. A non-transitory computer-readable medium storing instructions that, when executed by a computing device, cause:
receiving a first Internet Protocol (IP) stream comprising a first video component of multidimensional content, wherein the first IP stream does not comprise audio;
receiving a second IP stream comprising a second video component of the multidimensional content and comprising audio;
synchronizing the first video component received via the first IP stream with the second video component received via the second IP stream, comprising generating a frame synchronized video signal comprising the first video component and the second video component;
generating a first video content stream comprising the frame synchronized vide
