Methods and apparatus for decoded picture buffer (DPB) management in single loop decoding for multi-view video
View Patent ↗There are provided methods and apparatus for decoded picture buffer (DPB) management in single loop decoding for multi-view video. An apparatus includes a decoder ( 200 ) for decoding a picture corresponding to at least one view of at least two views of multi-view video content. The picture is decoded in support of decoded picture buffer management for single loop decoding using inter-view prediction.
1. An apparatus, comprising:
a decoder for decoding a picture corresponding to at least one view of at least two views of multi-view video content, wherein the picture is decoded in support of decoded picture buffer management for single loop decoding using inter-view prediction,
wherein said decoder generates a dummy picture for storage in a decoded picture buffer in support of the decoded picture buffer management, the dummy picture generated for a particular inter-view reference picture from among at least one of non-anchor pictures and anchor pictures of a reference view.
2. The apparatus of claim 1 , wherein the at least one view is a current view, the at least two views include the reference view with respect to the current view, and wherein the at least one view is capable of being reconstructed without a complete sample reconstruction of at least one of the non-anchor pictures and the anchor pictures of the reference view.
3. The apparatus of claim 1 , wherein a sample value of the dummy picture is settable to any value.
4. The apparatus of claim 1 , wherein the dummy picture is prohibited from use as an inter-view reference for the picture, and wherein only parsed syntax values corresponding to the dummy picture are used to decode the picture.
5. The apparatus of claim 1 , wherein said decoder omits a given inter-view reference picture for the picture from a reference picture list, when the picture is capable of being decoded without a complete sample reconstruction of the given inter-view reference picture.
6. The apparatus of claim 5 , wherein said decoder determines whether the picture is capable of being decoded without the complete sample reconstruction of the given inter-view reference picture based upon at least one high level syntax element.
7. The apparatus of claim 5 , wherein said decoder decodes the picture using decoded syntax of the given inter-view reference picture as a prediction for the picture.
8. A method, comprising:
decoding a picture corresponding to at least one view of at least two views of multi-view video content, wherein the picture is decoded in support of decoded picture buffer management for single loop decoding using inter-view prediction, wherein said decoding step comprises generating a dummy picture for storage in a decoded picture buffer in support of the decoded picture buffer management, the dummy picture generated for a particular inter-view reference picture from among at least one of non-anchor pictures and anchor pictures of a reference view.
9. The method of claim 8 , wherein the at least one view is a current view, the at least two views include the reference view with respect to the current view, and wherein the at least one view is capable of being reconstructed without a complete sample reconstruction of at least one of the non-anchor pictures and the anchor pictures of the reference view.
10. The method of claim 8 , wherein a sample value of the dummy picture is settable to any value.
11. The method of claim 8 , wherein the dummy picture is prohibited from use as an inter-view reference for the picture, and wherein only parsed syntax values corresponding to the dummy picture are used to decode the picture.
12. The method of claim 8 , wherein said decoding step comprises omitting a given inter-view reference picture for the picture from a reference picture list, when the picture is capable of being decoded without a complete sample reconstruction of the given inter-view reference picture.
13. The method of claim 12 , wherein said decoding step comprises determining whether the picture is capable of being decoded without the complete sample reconstruction of the given inter-view reference picture based upon at least one high level syntax element.
14. The method of claim 12 , wherein said decoding step decodes the picture using decoded syntax of the given inter-view reference picture as a prediction for the picture.
15. The apparatus of claim 1 , wherein the at least one view is a current view, the at least two views include the reference view with respect to the current view, and wherein the at least one view is capable of being reconstructed without a complete sample reconstruction of the anchor pictures of the reference view.
16. The method of claim 8 , wherein the at least one view is a current view, the at least two views include the reference view with respect to the current view, and wherein the at least one view is capable of being reconstructed without a complete sample reconstruction of the anchor pictures of the reference view.
17. The apparatus of claim 1 , wherein the dummy picture is prohibited from use as an inter-view reference for the picture, and wherein only parsed syntax values corresponding to at least motion information for the dummy picture are used to decode the picture.
18. The method of claim 8 , wherein the dummy picture is prohibited from use as an inter-view reference for the picture, and wherein only parsed syntax values corresponding to at least motion information for the dummy picture are used to decode the picture.
