Abstract

An apparatus may include a memory to store a video frame, a processor circuit and a selective encoding component for execution on the processor to perform selective encoding of the video frame, the selective encoding to classify the video frame into a primary object region and a background region, and encode the primary object region at a first quality level and the background region at a background quality level, the first quality level to comprise a higher quality level than the background quality level.

Claims

1. An apparatus, comprising:

a memory to store a video frame;

a processor circuit; and

a selective encoding component for execution on the processor circuit to perform selective encoding of the video frame, the selective encoding to classify the video frame into a primary object region and a background region, and encode the primary object region at a first quality level and the background region at a background quality level, the first quality level to comprise a higher quality level than the background quality level.

2. The apparatus of claim 1, the selective encoding component for execution on the processor to perform selective encoding when bandwidth falls below a bandwidth threshold.

3. The apparatus of claim 1, the selective encoding component for execution on the processor to perform a facial recognition procedure for pixels within the video frame and assign facial regions that are identified by the facial recognition procedure as primary object regions.

4. The apparatus of claim 1, the selective encoding component for execution on the processor to generate a selectively encoded video stream comprising a multiplicity of selectively encoded video frames when a signal indicating low bandwidth is received.

5. The apparatus of claim 1, the selective encoding component for execution on the processor to receive a user selected pixel region and selectively encode an object within the video frame at the first quality level based upon the user selected pixel region.

6. The apparatus of claim 1, the selective encoding component for execution on the processor to generate position information that identifies pixel coordinates in a video frame for the primary object region.

7. The apparatus of claim 1, the selective encoding component for execution on the processor to switch classification as a primary object region from a first region associated with a first object to a second region associated with a second object in the video frame.

8. The apparatus of claim 1, the selective encoding component for execution on the processor to classify an additional region in the video frame as a secondary object region, and encode the secondary object region at a second quality level less than the first quality level and higher than the background quality level.

9. The apparatus of claim 1, the primary object region comprising two or more separate regions of the video frame.

10. The apparatus of claim 1, the selective encoding component for execution on the processor to generate a bitmask that identifies pixels of the data frame corresponding to the background region.

11. The apparatus of claim 1, the selective encoding component for execution on the processor to perform selective encoding based upon signals indicative of user activity.

12. At least one computer-readable storage medium comprising instructions that, when executed, cause a system to perform, responsive to receipt of a video frame, selective encoding of the video frame, the selective encoding to classify the video frame into a primary object region and background region, and encode the primary object region at a first quality level and the background region at a background quality level, the first quality level to comprise a higher quality level than the background quality level.

13. The at least one computer-readable storage medium of claim 12 comprising instructions that, when executed, cause a system to perform selective encoding when bandwidth falls below a bandwidth threshold.

14. The at least one computer-readable storage medium of claim 12 comprising instructions that, when executed, cause a system to perform a facial recognition procedure for pixels within the video frame and assign facial regions that are identified by the facial recognition procedure as primary object regions.

15. The at least one computer-readable storage medium of claim 12 comprising instructions that, when executed, cause a system to generate a selectively encoded video stream comprising a multiplicity of selectively encoded video frames when a signal indicating low bandwidth is received.

16. The at least one computer-readable storage medium of claim 12 comprising instructions that, when executed, cause a system to receive a user selected pixel region and selectively encode an object within the video frame at the first quality level based upon the user selected pixel region.

17. The at least one computer-readable storage medium of claim 12 comprising instructions that, when executed, cause a system to generate position information that identifies pixel coordinates in a video frame for the primary object region.

18. The at least one computer-readable storage medium of claim 12 comprising instructions that, when executed, cause a system to classify an additional a region in the video frame as a secondary object region, and encode the secondary object region at a second quality level less than the first quality level and higher than the background quality level.

19. A method, comprising:

responsive to receipt of a video frame, performing selective encoding of the video frame, the selective encoding comprising;

classifying the video frame into a primary object region and background region;

encoding the primary object region at a first quality level; and

encoding background regions of the video frame at a background quality level less than the first quality level.

20. The method of claim 19, comprising performing selective encoding when bandwidth falls below a bandwidth threshold.

21. The method of claim 19, comprising performing a facial recognition procedure for pixels within the video frame and assign facial regions that are identified by the facial recognition procedure as primary object regions.

22. The method of claim 19, comprising generating position information that identifies pixel coordinates in a video frame for the primary object region.

23. The method of claim 19, comprising classifying an additional a region in the video frame as a secondary object region, and encoding the secondary object region at a second quality level less than the first quality level and higher than the background quality level.
