Abstract

Media sources that deliver at least portions of media content to viewer systems are described. The media content represents a plurality of camera perspectives of a single media product. A first request and a second request are both received. The first request is from a first viewer system and the second request is from a second viewer system. The first request is responded to by delivering a primary media stream to the first viewer system. The primary media stream contains a representation of at least a first of the plurality of camera perspectives. The second request is responded to by delivering both the primary media stream and a secondary media stream to the second viewer system. The secondary media stream contains a representation of at least a second of the plurality of camera perspectives. The second viewer system combines the primary and secondary media streams to display a three-dimensional view.

Claims

1. A method used by a media source to deliver at least portions of media content to a first viewer system and a second viewer system, the media content being three-dimensional content representing a first visual perspective, a second visual perspective, a third visual perspective and a fourth visual perspective, the method comprising:

receiving a first request from the first viewer system for a primary media stream;

constructing the primary media stream from a first portion of the media content, the first portion containing representations of at least one but not all of the first visual perspective, the second visual perspective, the third visual perspective and the fourth visual perspective;

delivering the primary media stream to the first viewer system;

receiving a second request from the second viewer system for a second media stream;

constructing a secondary media stream from a second portion of the media content, the second portion containing representations of at least one but not all of the first visual perspective, the second visual perspective, the third visual perspective and the fourth visual perspective; and

delivering both the primary media stream and the secondary media stream to the second viewer system.

2. The method of claim 1, wherein the primary media stream supports a two-dimensional presentation, and both the primary media stream and the secondary media stream together support a three-dimensional presentation.

3. The method of claim 1, wherein the primary media stream represents at least two of the first visual perspective, the second visual perspective, the third visual perspective and the fourth visual perspective.

4. The method of claim 1, wherein the primary media stream is multi-cast to both the first viewer system and the second viewer system.

5. The method of claim 4, wherein the second request is received after having delivered a first part of the primary media stream to the first viewer system, and further comprising:

constructing a tertiary media stream based on the first part of the primary media stream; and

delivering the tertiary media stream to the second viewer system.

6. The method of claim 4, further comprising removing at least one of the first viewer system and the second viewer system from the multi-cast.

7. A media source that delivers at least portions of media content to a first viewer system and a second viewer system, the media content representing a plurality of camera perspectives of a single media product, the media source comprising:

a communication interface through which a first request and a second request are both received, the first request being from the first viewer system and the second request being from the second viewer system; and

a processor that responds to the first request from the first viewer system by delivering a primary media stream via the communication interface to the first viewer system, the primary media stream containing a representation of at least a first of the plurality of camera perspectives;

the processor responds to the second request from the second viewer system by delivering both the primary media stream and a secondary media stream to the second viewer system via the communication interface, the secondary media stream containing a representation of at least a second of the plurality of camera perspectives.

8. The media source of claim 7, wherein the primary media stream supports a two-dimensional presentation, and both the primary media stream and the secondary media stream together support a three-dimensional presentation.

9. The media source of claim 7, wherein the primary media stream represents at least two of the plurality of camera perspectives.

10. The media source of claim 7, wherein at least a portion of the primary media stream is multi-cast to both the first viewer system and the second viewer system.

11. The media source of claim 7, wherein the secondary media stream is not delivered to the first viewer system.

12. The media source of claim 10, wherein the processor receives the second request after having delivered a first part of the primary media stream to the first viewer system, and the processor delivers a tertiary media stream to the second viewer system based on the first part of the primary media stream.

13. The media source of claim 10, wherein the processor removes at least one of the first viewer system and the second viewer system from the multi-cast.

14. The media source of claim 13, wherein the removal from the multi-cast of the primary media stream is based on a difference between a first communication characteristic associated with the first viewer system and a second communication characteristic associated with the second viewer system.

15. The media source of claim 7, wherein the primary media stream is multi-cast to both the first viewer system and the second viewer system if both a first communication characteristic of the first viewer system and a second communication characteristic of the second viewer system are relatively similar.

16. Viewer system circuitry that receives at least a portion of media content from a media source, the media source simultaneously servicing multiple viewers at differing premises, the media content representing a plurality of camera perspectives of a single media product, the viewer system circuitry supporting display of the at least the portion of the media content via a screen assembly, the viewer system circuitry comprising:

communication interface circuitry operable to communicatively couple with the media source;

display interface circuitry operable to communicatively couple with the screen assembly; and

processing circuitry that delivers to the media source a first request for the at least the portion of the media content received, the delivery being via the communication interface circuitry;

the processing circuitry receives, from the media source in response to the first request and via the communication interface circuitry, primary media content and secondary media content, the primary media content containing a representation of at least a first of the plurality of camera perspectives, the secondary media content containing a representation of at least a second of the plurality of camera perspectives; and

the processing circuitry establishes a communication flow toward the screen assembly via the display interface circuitry, the communication flow representing at least both of the first of the plurality of camera perspectives and the second of the plurality of camera perspectives.

17. The viewer system circuitry of claim 16, wherein the primary media content is provided by the media source in a multi-cast format.

18. The viewer system circuitry of claim 16, wherein at least a portion of the secondary media content is provided by the media source in a uni-cast format.

19. The viewer system circuitry of claim 16, wherein the processing circuitry directs storage of at least a representation of the primary media content and the secondary media content.

20. The viewer system circuitry of claim 16, wherein the processor receives from the media source tertiary media content, the tertiary media content being a beginning portion of the single media product not represented in the primary media content or the secondary media content.

21. The viewer system circuitry of claim 16, wherein the primary media content is provided by the media source with destination addressing that changes over time.
