Coding concept allowing efficient multi-view/layer coding
Various concepts which further improve multi-view/layer coding concepts, are described.
1. A decoder configured to reconstruct a plurality of views from a data stream using inter-view prediction from a first view to a second view, wherein the decoder is configured to perform, based on a signaling in the data stream, the inter-view prediction at spatial segment boundaries of spatial segments into which the first view is partitioned, wherein the signaling indicates a guarantee that the inter-view prediction from the first view to the second view for a current portion of the second view is based on information stemming from only a first spatial segment of the spatial segments of the first view without combining information from another spatial segment of the spatial segments of the first view, wherein the first spatial segment of the first view is spatially co-located with the current portion of the second view.
2. The decoder of claim 1 , wherein the inter-view prediction includes predicting sample values of the current portion of the second view.
3. The decoder of claim 1 , wherein the inter-view prediction includes predicting motion vectors associated with the current portion of the second view based on motion vectors associated with the first spatial segment of the first view.
4. The decoder of claim 1 , wherein the change in the inter-view prediction at spatial segment boundaries is associated with a selection of a binarization or a probability estimate of a syntax element of the current portion of the second view.
5. An encoder configured to encode a plurality of views into a data stream using inter-view prediction from a first view to a second view, wherein the encoder is configured to insert a signaling in the data stream, wherein the inter-view prediction at spatial segment boundaries of spatial segments into which the first view is partitioned is performed based on the signaling, wherein the signaling indicates a guarantee that the inter-view prediction from the first view to the second view for a current portion of the second view is based on information stemming from only a first spatial segment of the spatial segments of the first view without combining information from another spatial segment of the spatial segments of the first view, wherein the first spatial segment of the first view is spatially co-located with the current portion of the second view.
6. The encoder of claim 5 , wherein the inter-view prediction includes predicting sample values of the current portion of the second view.
7. The encoder of claim 5 , wherein the inter-view prediction includes predicting motion vectors associated with the current portion of the second view based on motion vectors associated with the first spatial segment of the first view.
8. The encoder of claim 5 , wherein the change in the inter-view prediction at spatial segment boundaries is associated with a selection of a binarization or a probability estimate of a syntax element of the current portion of the second view.
9. A non-transitory computer-readable medium for storing data associated with a video, comprising:
a data stream stored in the non-transitory computer-readable medium, the data stream comprising a signaling in the data stream, wherein the inter-view prediction at spatial segment boundaries of spatial segments into which the first view is partitioned is performed based on the signaling, wherein the signaling indicates a guarantee that the inter-view prediction from the first view to the second view for a current portion of the second view is based on information stemming from only a first spatial segment of the spatial segments of the first view without combining information from another spatial segment of the spatial segments of the first view, wherein the first spatial segment of the first view is spatially co-located with the current portion of the second view.
10. The non-transitory computer-readable medium of claim 9 , wherein the inter-view prediction includes predicting sample values of the current portion of the second view.
11. The non-transitory computer-readable medium of claim 9 , wherein the inter-view prediction includes predicting motion vectors associated with the current portion of the second view based on motion vectors associated with the first spatial segment of the first view.
12. The non-transitory computer-readable medium of claim 9 , wherein the change in the inter-view prediction at spatial segment boundaries is associated with a selection of a binarization or a probability estimate of a syntax element of the current portion of the second view.
