Methods and apparatus for the use of slice groups in decoding multi-view video coding (MVC) information

1. An apparatus, comprising:

a decoder for decoding, from a single picture, at least two views corresponding to multi-view video content using multiple slice groups,

wherein the at least two views correspond to a same or similar scene, and

wherein said decoder decodes each of the at least two views as a respective separate one of the multiple slice groups.

2. The apparatus of claim 1 , wherein at least some of the multiple slice groups are compliant with an existing video coding standard or an existing video coding recommendation.

3. The apparatus of claim 1 , wherein at least some of the multiple slice groups are compliant with the International Organization for Standardization/International Electrotechnical Commission Moving Picture Experts Group-4 Part 10 Advanced Video Coding standard/International Telecommunication Union, Telecommunication Sector H.264 recommendation.

4. The apparatus of claim 1 , wherein said decoder uses a Supplemental Enhancement Information message to decode each of the at least two views as the respective separate one of the multiple slice groups.

5. The apparatus of claim 4 , wherein the Supplemental Enhancement Information message indicates that at least some of the multiple slice groups are motion constrained.

6. The apparatus of claim 1 , wherein said decoder reads a modified version of an existing Supplemental Enhancement Information message of an existing video coding standard or video coding recommendation, the existing Supplemental Enhancement Information message modified to include slice group identifier information.

7. The apparatus of claim 1 , wherein said decoder reads a modified version of a Picture Parameter Set, the Picture Parameter Set modified to signal view identifier information and slice group identifier information for the at least two views.

8. The apparatus of claim 7 , wherein the Picture Parameter Set is modified to specify at least one of a slice group type 2 and a slice group type 6.

9. The apparatus of claim 8 , wherein a mapping is provided from the view identifier information to the slice group identifier information, when the slice group type 6 is specified in the Picture Parameter Set.

10. The apparatus of claim 1 , wherein said decoder determines that each of the at least two views is independently coded, using a high level syntax element.

11. The apparatus of claim 10 , wherein the high level syntax element corresponds to at least at one of a slice header level, a sequence parameter set level, a picture parameter set level, a view parameter set level, a network abstraction layer unit header level, and a level corresponding to a supplemental enhancement information message.

12. In a video decoder, a method, comprising:

decoding, from a single picture, at least two views corresponding to multi-view video content using multiple slice groups,

wherein the at least two views correspond to a same or similar scene, and

wherein said decoding step decodes each of the at least two views as a respective separate one of the multiple slice groups.

13. The method of claim 12 , wherein at least some of the multiple slice groups are compliant with an existing video coding standard or an existing video coding recommendation.

14. The method of claim 12 , wherein at least some of the multiple slice groups are compliant with the International Organization for Standardization/International Electrotechnical Commission Moving Picture Experts Group-4 Part 10 Advanced Video Coding standard/International Telecommunication Union, Telecommunication Sector H.264 recommendation.

15. The method of claim 12 , wherein said decoding step uses a Supplemental Enhancement Information message to decode each of the at least two views as the respective separate one of the multiple slice groups.

16. The method of claim 15 , wherein the Supplemental Enhancement Information message indicates that at least some of the multiple slice groups are motion constrained.

17. The method of claim 12 , wherein said decoding step comprises reading a modified version of an existing Supplemental Enhancement Information message of an existing video coding standard or video coding recommendation, the existing Supplemental Enhancement Information message modified to include slice group identifier information.

18. The method of claim 12 , wherein said decoding step comprises reading a modified version of a Picture Parameter Set, the Picture Parameter Set modified to signal view identifier information and slice group identifier information for the at least two views.

19. The method of claim 18 , wherein the Picture Parameter Set is modified to specify at least one of a slice group type 2 and a slice group type 6.

20. The method of claim 19 , wherein a mapping is provided from the view identifier information to the slice group identifier information, when the slice group type 6 is specified in the Picture Parameter Set.

21. The method of claim 12 , wherein said decoding step comprises determining that each of the at least two views is independently coded, using a high level syntax element.

22. The method of claim 21 , wherein the high level syntax element corresponds to at least at one of a slice header level, a sequence parameter set level, a picture parameter set level, a view parameter set level, a network abstraction layer unit header level, and a level corresponding to a supplemental enhancement information message.

23. A non-transitory computer-readable storage media having video signal data encoded thereupon, comprising:

at least two views corresponding to multi-view video content encoded by an encoder into a single picture using multiple slice groups,

wherein the at least two views correspond to a same or similar scene, and

wherein each of the at least two views is coded as a respective separate one of the multiple slice groups.
