Abstract:
Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. For example, processing circuitry decodes prediction information for a block in a current picture from a coded video bitstream. The prediction information is indicative of an inter prediction mode that signals an offset associated with one of base motion vector predictor candidates in a candidate list. The processing circuitry constructs the candidate list with one or more existing base motion vector predictor candidates and adds a new motion vector predictor into the candidate list when the new motion vector predictor satisfies a spacing requirement to the one or more existing base motion vector predictor candidates. The processing circuitry decodes an index of a specific base motion vector predictor candidate in the candidate list and the offset to determine a final motion vector, and reconstructs samples of the block according to the final motion vector.

Claim (Index 1):
A method for video decoding in a decoder, comprising:\n decoding prediction information for a block in a current picture from a coded video bitstream, the prediction information being indicative of an inter prediction mode that signals an offset for each base motion vector predictor candidate included in a candidate list, each base motion vector predictor candidate associated with a respective coverage window; determining whether a new motion vector satisfies a spacing requirement that specifies that a coverage window of the new motion vector does not overlap with the respective coverage window of each base motion vector predictor candidate in the candidate list; adding the new motion vector predictor into the candidate list in response to the determination that the new motion vector predictor satisfies the spacing requirement; decoding an index of a specific base motion vector predictor candidate in the candidate list and the offset associated with the specific base motion vector predictor candidate to determine a final motion vector for block reconstruction; and reconstructing at least a sample of the block according to the final motion vector.
