Abstract

In an embodiment, a UE is participating in a communication session that shares a video stream with target UE(s). The UE receives user input that identifies high priority portion(s) of the video stream. The UE generates a first video feed based on the high priority portion(s) and a second video feed based at least on other portion(s) of the video stream. The first and second video feeds are exchanged with the target UE(s) on first and second links, respectively. In an example, the first link that carries the first video feed can be allocated QoS. The target UE(s) combine the first and second video feeds to reconstruct a version of the video stream, and then present the reconstructed version of the video stream.

Claims

1. A method of operating a given user equipment (UE) that is participating in a communication session that shares a video stream with at least one target UE, comprising:

receiving user input that identifies a set of high priority portions of the video stream;

generating a first video feed for the video stream based on the set of high priority portions of the video stream;

generating a second video feed for the video stream based at least in part on one or more other portions of the video stream;

transmitting the first video feed to the at least one target UE on a first link; and

transmitting the second video feed to the at least one target UE on a second link with less reliability relative to the first link.

2. The method of claim 1, wherein the user input corresponds to an explicit user selection of the set of high priority portions of the video stream.

3. The method of claim 2, wherein the explicit user selection corresponds to a user of the given UE physically touching the set of high priority portions via a touchscreen interface of the given UE while the video stream is being displayed on the given UE.

4. The method of claim 1, further comprising:

adding one or more additional portions of the video stream to the set of high priority portions based on one or more secondary factors that are not related to the user input.

5. The method of claim 4, wherein the one or more secondary factors include a degree of motion detected in the one or more additional portions.

6. The method of claim 1, wherein the first video feed includes only the set of high priority portions of the video stream and the second video feed includes each portion of the video stream, such that the first video feed has a lower resolution relative to the second video feed.

7. The method of claim 1,

wherein the first video feed includes the set of high priority portions of the video stream in combination with a blacked out portion of each other portion of the video stream,

wherein the second video feed includes portion of the video stream, and

wherein the first and second video feeds have equal resolutions.

8. The method of claim 1,

wherein the first link is allocated Quality of Service (QoS) with a threshold level of Guaranteed Bit Rate (GBR), and

wherein the second link is not allocated QoS with the threshold level of GBR.

9. The method of claim 1,

wherein the first and second links are each allocated Quality of Service (QoS) with a threshold level of Guaranteed Bit Rate (GBR), and

wherein the first link is allocated higher GBR relative to the second link.

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

determining, based on the user input, to lock onto a set of objects within the video stream; and

locking onto the set of objects by identifying the set of high priority portions of the video stream as a current set of portions of the video stream containing the set of objects.

11. The method of claim 10, wherein the user input corresponds to a user of the given UE zooming in on the set of objects.

12. The method of claim 11,

wherein the user input corresponds to the user of the given UE performing a digital zoom-in on the set of objects, or

wherein the user input corresponds to the user of the given UE performing a manual zoom-in on the set of objects by physically moving a camera of the given UE closer to the set of objects.

13. The method of claim 10, wherein the user input corresponds to an explicit user selection of the set of objects by a user of the given UE.

14. The method of claim 10, further comprising:

determining, based on additional user input, to lock onto another set of objects within the video stream; and

locking, in response to the determination to lock onto the other set of objects, onto the other set of objects by identifying the set of high priority portions of the video stream as the current set of portions of the video stream containing the other set of objects.

15. The method of claim 10, wherein the locking of the set of objects is canceled in response to the determination to lock onto the other set of objects such that the set of high priority portions are no longer identified as the current set of portions of the video stream containing the set of objects.

16. The method of claim 10, further comprising:

starting a lock timer; and

canceling the locking of the set of objects in response to expiration of the lock timer such that the set of high priority portions are no longer identified as the current set of portions of the video stream containing the set of objects.

17. The method of claim 16, wherein the lock timer is extended based on the set of objects remaining visible within the video stream.

18. The method of claim 1, wherein the video stream is displayed on a display device of the given UE.

19. The method of claim 1, wherein the video stream is not displayed on a display device of the given UE.

20. A method of operating a target user equipment (UE) that is participating in a communication session that shares a video stream with a given UE, comprising:

receiving a first video feed containing a set of high priority portions of the video stream on a first link;

receiving a second video feed for the video stream based at least in part on one or more other portions of the video stream;

combining the first and second video feeds to reconstruct a version of the video stream; and

presenting the reconstructed version of the video stream.

21. The method of claim 20, wherein the first video feed includes only the set of high priority portions of the video stream and the second video feed includes each portion of the video stream, such that the first video feed has a lower resolution relative to the second video feed.

22. The method of claim 21, wherein the reconstructing includes:

populating the reconstructed version of the video stream with the set of high priority portions of the video stream and one or more portions from the second video feed that correspond to the set of high priority portions within the first video feed.

23. The method of claim 20,

wherein the first video feed includes the set of high priority portions of the video stream in combination with one or more blacked out portions of one or more other portions of the video stream,

wherein the second video feed includes portion of the video stream, and

wherein the first and second video feeds have equal resolutions.

24. The method of claim 23, wherein the reconstructing includes:

populating the reconstructed version of the video stream with the set of high priority portions of the video stream and one or more portions from the second video feed that correspond to the one or more blacked out portions from the first video feed.

25. The method of claim 20,

wherein the first link is allocated Quality of Service (QoS) with a threshold level of Guaranteed Bit Rate (GBR), and

wherein the second link is not allocated QoS with the threshold level of GBR.

26. The method of claim 26,

wherein the first and second links are each allocated Quality of Service (QoS) with a threshold level of Guaranteed Bit Rate (GBR), and

wherein the first link is allocated higher GBR relative to the second link.

27. A user equipment (UE) that is participating in a communication session that shares a video stream with at least one target UE, comprising:

logic configured to generate a first video feed for the video stream based on the set of high priority portions of the video stream;

logic configured to generate a second video feed for the video stream based at least in part on one or more other portions of the video stream;

logic configured to transmit the first video feed to the at least one target UE on a first link; and

logic configured to transmit the second video feed to the at least one target UE on a second link with less reliability relative to the first link.

28. A target user equipment (UE) that is participating in a communication session that shares a video stream with a given UE, comprising:
