Abstract

There are provided a method and apparatus for providing reduced resolution update mode for multi-view video coding. A video encoder includes an encoder for encoding a picture using a reduced resolution update mode. The picture is one of a set of pictures corresponding to multi-view content having different view points with respect to a same or similar scene. The picture represents one of the different view points.

First claim

The invention claimed is:

1. A video decoder, comprising:
a decoder for decoding a picture using a reduced resolution update mode, the picture being one of a set of pictures corresponding to multi-view content having different view points with respect to a same or similar scene, the picture representing one of the different view points wherein the reduced resolution update mode is used for at least one of view prediction and temporal prediction,
wherein the reduced resolution update mode is used on a slice basis; and
wherein said decoder applies a deblocking filtering operation to reduced resolution update block edges of a slice partitioned from the picture when the reduced resolution update mode is used for the slice, and a strength of the deblocking filtering operation is adapted based on at least one of the reduced resolution update mode and prediction information.

2. The video decoder of claim 1 , wherein the reduced resolution update mode is used for a non-reference slice in the multi-view video scene.

3. The video decoder of claim 1 , wherein the reduced resolution update mode is used for at least some views in the multi-view video scene.

4. The video decoder of claim 1 , wherein the reduced resolution update mode is used for a particular temporal instance in the multi-view video scene.

5. A video decoder, comprising:
a decoder for decoding a picture using a reduced resolution update mode, the picture being one of a set of pictures corresponding to multi-view content having different view points with respect to a same or similar scene, the picture representing one of the different view points wherein the reduced resolution update mode is used for at least one of view prediction and temporal prediction, wherein said decoder applies a deblocking filtering operation to the picture, the deblocking filtering operation having a filter strength adaptable based upon at least one of the reduced resolution update mode and prediction information.

6. A video decoding method, comprising:
decoding a picture using a reduced resolution update mode, the picture being one of a set of pictures corresponding to multi-view content having different view points with respect to a same or similar scene, the picture representing one of the different view points wherein the reduced resolution update mode is used for at least one of view prediction and temporal prediction,
wherein the reduced resolution update mode is used on a slice basis; and
applying a deblocking filtering operation to reduced resolution update block edges of a slice partitioned from the picture when the reduced resolution update mode is used for the slice, and a strength of the deblocking filtering operation is adapted based on at least one of the reduced resolution update mode and prediction information.

7. The method of claim 6 , wherein the reduced resolution update mode is used for a non-reference slice in the multi-view video scene.

8. The method of claim 6 , wherein the reduced resolution update mode is used for at least some views in the multi-view video scene.

9. The method of claim 6 , wherein the reduced resolution update mode is used for a particular temporal instance in the multi-view video scene.

10. A video decoding method, comprising:
decoding a picture using reduced resolution update mode, the picture being one of a set of pictures corresponding to multi-view content having different view points with respect to a same or similar scene, the picture representing one of the different view points wherein the reduced resolution update mode is used for at least one of view prediction and temporal prediction,
wherein said decoding step decodes the picture to provide a resultant bitstream compliant with at least one of 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 and an extension thereto, further comprising applying a deblocking filtering operation to the picture, the deblocking filtering operation having a filter strength adaptable based upon at least one of the reduced resolution update mode and prediction information.
