Methods and apparatus for the use of slice groups in encoding multi-view video coding (MVC) information
There are provided methods and apparatus for the use of slice groups in encoding and decoding multi-view video coding (MVC) information. An apparatus and method are described which encodes at least two views corresponding to multi-view video content using multiple slice groups. Furthermore, an apparatus and method are described for decoding at least two views corresponding to multi-view video content using multiple slice groups.
1. A transmitting method comprising:
transmitting at least two views corresponding to multi-view video content encoded 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.
2. The method of claim 1 , wherein transmitting comprises transmitting a Supplemental Enhancement Information message used to code each of the at least two views as the respective separate one of the multiple slice groups.
3. The method of claim 2 , wherein the Supplemental Enhancement Information message indicates that at least some of the multiple slice groups are motion constrained.
4. The method of claim 1 , wherein transmitting comprises transmitting 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 being modified to include slice group identifier information.
5. The method of claim 1 , wherein transmitting comprises transmitting a modified version of a Picture Parameter Set, the Picture Parameter Set being modified to signal view identifier information and slice group identifier information for the at least two views.
6. The method of claim 1 , wherein transmitting comprises signaling that each of the at least two views is independently coded, using a high level syntax element.
7. A receiving method, comprising:
receiving encoded video signal data comprising at least two views corresponding to multi-view video content encoded 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.
8. The method of claim 7 , wherein receiving comprises receiving a Supplemental Enhancement Information message used to code each of the at least two views as the respective separate one of the multiple slice groups.
9. The method of claim 8 , wherein the Supplemental Enhancement Information message indicates that at least some of the multiple slice groups are motion constrained.
10. The method of claim 7 , wherein receiving comprises receiving 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.
11. The method of claim 7 , wherein receiving comprises receiving 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.
12. The method of claim 7 , wherein receiving comprises determining that each of the at least two views is independently coded, using a high level syntax element.
13. A non-transitory machine readable medium having stored thereon machine executable instructions that, when executed, implement an encoding method, the encoding method comprising:
encoding, into 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 encoding comprises encoding each of the at least two views is coded as a respective separate one of the multiple slice groups.
14. The non-transitory machine readable medium of claim 13 , wherein encoding comprises encoding a Supplemental Enhancement Information message used to code each of the at least two views as the respective separate one of the multiple slice groups.
15. The non-transitory machine readable medium of claim 14 , wherein the Supplemental Enhancement Information message indicates that at least some of the multiple slice groups are motion constrained.
16. The non-transitory machine readable medium of claim 13 , wherein encoding comprises encoding 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 being modified to include slice group identifier information.
17. The non-transitory machine readable medium of claim 13 , wherein encoding comprises encoding a modified version of a Picture Parameter Set, the Picture Parameter Set being modified to signal view identifier information and slice group identifier information for the at least two views.
18. The non-transitory machine readable medium of claim 13 , wherein encoding comprises signaling that each of the at least two views is independently coded, using a high level syntax element.
19. A non-transitory machine readable medium having stored thereon machine executable instructions that, when executed, implement a decoding method, the decoding 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 decoding comprises decoding each of the at least two views as a respective separate one of the multiple slice groups.
20. The non-transitory machine readable medium of claim 19 , wherein decoding comprises decoding a Supplemental Enhancement Information message used to code each of the at least two views as the respective separate one of the multiple slice groups.
21. The non-transitory machine readable medium of claim 20 , wherein the Supplemental Enhancement Information message indicates that at least some of the multiple slice groups are motion constrained.
22. The non-transitory machine readable medium of claim 19 , wherein decoding comprises decoding 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.
23. The non-transitory machine readable medium of claim 19 , wherein decoding comprises decoding 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.
24. The non-transitory machine readable medium of claim 19 , wherein decoding comprises determining that each of the at least two views is independently coded, using a high level syntax element.
