Abstract

There are provided methods and apparatus for motion skip mode with multiple inter-view reference pictures. An apparatus includes an encoder for encoding an image block relating to multi-view video content by performing a selection, for the image block, of at least one of an inter-view reference picture list from a set of inter-view reference picture lists, an inter-view reference picture from among a set of inter-view reference pictures, and a disparity vector from among a set of disparity vectors corresponding to the inter-view reference picture. The encoder extracts motion information for the image block based on at least one of the inter-view reference picture list, the inter-view reference picture, and disparity vector.

First claim

The invention claimed is:

1. An apparatus, comprising an encoder for encoding an image block relating to multi-view video content, said apparatus comprising further comprising a processor configured to:
i) select, for the image block, an inter-view reference picture list from a set of two inter-view reference picture lists, an inter-view reference picture from said selected inter-view reference picture list, and a disparity vector from among a set of disparity vectors corresponding to said selected inter-view reference picture, the inter-view reference picture and the disparity vector being selected based on neighboring macroblocks with respect to the image block;
ii) identify a corresponding inter-view block based on said selected inter-view reference picture list, said selected inter-view reference picture, and said selected disparity vector; and
iii) extract motion information for the image block from the corresponding inter-view block;
wherein said selecting comprises, when more than one neighboring macroblock use inter-view prediction, selecting, from inter-view reference pictures associated with said neighboring macroblocks, an inter-view picture with the smallest reference index and its associated disparity vector.

2. A method, comprising encoding an image block relating to multi-view video content, wherein said encoding comprises:
i) performing a selection, for the image block, of an inter-view reference picture list from a set of two inter-view reference picture lists, an inter-view reference picture from said selected inter-view reference picture list, and a disparity vector from among a set of disparity vectors corresponding to said selected inter-view reference picture, the inter-view reference picture and the disparity vector being selected based on neighboring macroblocks with respect to the image block;
ii) identifying a corresponding inter-view block based on said selected inter-view reference picture list, said selected inter-view reference picture, and said selected disparity vector; and
iii) extracting motion information for the image block from the corresponding inter-view block;
wherein said selecting comprises, when more than one neighboring macroblock use inter-view prediction, selecting, from inter-view reference pictures associated with said neighboring macroblocks, an inter-view picture with the smallest reference index and its associated disparity vector.

3. An apparatus, comprising a decoder for decoding an image block relating to multi-view video content, said apparatus further comprising a processor to:
i) select, for the image block, an inter-view reference picture list from a set of two inter-view reference picture lists, an inter-view reference picture from said selected inter-view reference picture list, and a disparity vector from among a set of disparity vectors corresponding to said selected inter-view reference picture, the inter-view reference picture and the disparity vector being selected based on neighboring macroblocks with respect to the image block;
ii) identify a corresponding inter-view block based on said selected inter-view reference picture list, said selected inter-view reference picture, and said selected disparity vector; and
iii) extract motion information for the image block from the corresponding inter-view block,
wherein said selecting comprises, when more than one neighboring macroblock use inter-view prediction, selecting ( 960 , 965 ), from inter-view reference pictures associated with said neighboring macroblocks, an inter-view picture with the smallest reference index and its associated disparity vector.

4. A method, comprising decoding an image block relating to multi-view video content, wherein said decoding comprises:
i) performing a selection, for the image block, of an inter-view reference picture list from a set of two inter-view reference picture lists, an inter-view reference picture from said selected inter-view reference picture list, and a disparity vector from among a set of disparity vectors corresponding to said selected inter-view reference picture, the inter-view reference picture and the disparity vector being selected based on neighboring macroblocks with respect to the image block;
ii) identifying a corresponding inter-view block based on said selected inter-view reference picture list, said selected inter-view reference picture, and said selected disparity vector, and
iii) extracting motion information for the image block from the corresponding inter-view block,
wherein said selecting comprises, when more than one neighboring macroblock use inter-view prediction, selecting, from inter-view reference pictures associated with said neighboring macroblocks, an inter-view picture with the smallest reference index and its associated disparity vector.
