Abstract
A method for decoding. the method comprising: obtaining an ordered list of a plurality of positions in a spatial neighborhood of a current block in a picture; parsing the list in order until first motion information is available at one of the positions and second motion information is available at a position in a reference picture designated by the first motion information; using the second motion information to obtain at least one motion vector predictor candidate to be inserted in at least one list of motion vector predictor candidates used for predicting a motion vector used for the current block.
Claims23
A method for decoding, the method comprising:
- obtaining an ordered list of a plurality of positions in a spatial neighborhood of a current block in a picture;
- parsing the ordered list in order until first motion information is available at one of the plurality of positions and second motion information is available at a position in a reference picture designated by the first motion information;
- and
- using the second motion information to obtain at least one motion vector predictor candidate to be inserted in at least one list of motion vector predictor candidates used for predicting a motion vector used for the current block.
(canceled)
The method of claim 23 wherein the second position is before the fourth position in the ordered list of a plurality of positions.
(canceled)
A device for decoding, the device comprising electronic circuitry configured for:
- obtaining an ordered list of a plurality of positions in a spatial neighborhood of a current block in a picture;
- parsing the ordered list in order until first motion information is available at one of the plurality of positions and second motion information is available at a position in a reference picture designated by the first motion information;
- and
- using the second motion information to obtain at least one motion vector predictor candidate to be inserted in at least one list of motion vector predictor candidates used for predicting a motion vector used for the current block.
A device for coding, the device comprising electronic circuitry configured for:
- obtaining an ordered list of a plurality of positions in a spatial neighborhood of a current block in a picture;
- parsing the ordered list in order until first motion information is available at one of the plurality of positions and second motion information is available at a position in a reference picture designated by the first motion information;
- and
- using the second motion information to obtain at least one motion vector predictor candidate to be inserted in at least one list of motion vector predictor candidates used for predicting a motion vector used for the current block.
