Abstract:
A method and apparatus for video coding. In some examples, an apparatus includes receiving circuitry and processing circuitry. The processing circuitry decodes prediction information of a block in a current picture from a coded video bitstream. The prediction information includes an index for prediction offset associated with an affine model in an inter prediction mode. The affine model is used to transform between the block and a reference block in a reference picture that has been reconstructed. Further, the processing circuitry determines parameters of the affine model based on the index and a pre-defined mapping of indexes and offset values, and reconstructs at least a sample of the block according to the affine model.

Claim (Index 10):
The method of  claim 1 , further comprising:\n changing a first motion vector difference for a first control point according to the offset value associated with the first index; predicting a second motion vector difference for a second control point based on the first motion vector difference; decoding a prediction error to correct the second motion vector difference from the coded video bitstream; determining a first motion vector for the first control point and a second motion vector for the second control point based on the first motion vector difference and the corrected second motion vector difference; and deriving the affine model at least based on the first motion vector for the first control point and the second motion vector for the second control point.
