Abstract
There are provided methods and apparatus for multi-view video coding. A video encoder includes an encoder for encoding a block in a picture by choosing between temporal prediction and cross-view prediction to enable a prediction for the block. The picture is one of a set of pictures corresponding to multi-view video content and having different view points with respect to a same or similar scene. The picture represents one of the different view points. A high-level syntax is used to indicate the use of cross-view prediction for the block.
Claims13
A non-transitory processor readable medium having stored thereon an encoded bitstream, the encoded bitstream comprising:
- a first block in a picture, the first block being encoded using a disparity vector, the picture being one picture of a set of pictures corresponding to multi-view video content, the picture representing one of the different view points;
- and
- a second block in the picture, the second block being encoded using a motion vector,
- wherein a disparity vector predictor corresponding to the disparity vector is formed using only disparity vectors of blocks adjacent to the first block, and a motion vector predictor corresponding to the motion vector is formed using only motion vectors of blocks adjacent to the second block.
A method of video encoding, comprising:
- encoding a first block in a picture using a disparity vector, wherein the picture corresponds to multi-view video content;
- and
- encoding a second block in the picture using a motion vector,
- wherein a disparity vector predictor corresponding to the disparity vector is formed using only disparity vectors of blocks adjacent to the first block, and a motion vector predictor corresponding to the motion vector is formed using only motion vectors of blocks adjacent to the second block.
An apparatus for video encoding, comprising at least a memory and one or more processors, the one or more processors configured to:
- encode a first block in a picture using a disparity vector, wherein the picture corresponds to multi-view video content;
- and
- encode a second block in the picture using a motion vector,
- wherein a disparity vector predictor corresponding to the disparity vector is formed using only disparity vectors of blocks adjacent to the first block, and a motion vector predictor corresponding to the motion vector is formed using only motion vectors of blocks adjacent to the second block.
A method of video decoding, comprising:
- decoding a first block in a picture using a disparity vector, wherein the picture corresponds to multi-view video content;
- and
- decoding a second block in the picture using a motion vector,
- wherein a disparity vector predictor corresponding to the disparity vector is formed using only disparity vectors of blocks adjacent to the first block, and a motion vector predictor corresponding to the motion vector is formed using only motion vectors of blocks adjacent to the second block.
An apparatus for video decoding, comprising at least a memory and one or more processors, the one or more processors configured to:
- decode a first block in a picture using a disparity vector, wherein the picture corresponds to multi-view video content;
- and
- decode a second block in the picture using a motion vector,
- wherein a disparity vector predictor corresponding to the disparity vector is formed using only disparity vectors of blocks adjacent to the first block, and a motion vector predictor corresponding to the motion vector is formed using only motion vectors of blocks adjacent to the second block.
