Abstract:
Aspects of the disclosure provide a method and an apparatus including processing circuitry for video coding. The processing circuitry decodes prediction information of a block of a current picture in a coded video bitstream and determines a motion prediction mode based on the prediction information. The processing circuitry determines that the block is to be predicted based on multiple reference pictures that include a first and a second reference pictures. The processing circuitry obtains, based on the prediction information, first motion vector (MV) prediction information for the first reference picture and determines second MV prediction information for the second reference picture based on the first MV prediction information, the motion prediction mode, and temporal relationships among the first, the second, and the current pictures in a video sequence. The processing circuitry reconstructs a sample in the block based on the first and the second MV prediction information.

Claim (Index 17):
The apparatus of  claim 12 , wherein\n the prediction information includes an affine flag indicating that the motion prediction mode is an affine prediction mode limited to rotation and translation of the block with respect to the first and second reference pictures, the affine flag being signaled in the coded video bitstream; the prediction information indicates that the first and second reference pictures are in opposite directions relative to the current picture in the video sequence; the first MV prediction information including a first angular parameter and a first translation MV is signaled in the coded bitstream, the first angular parameter indicating the rotation and the first translation MV indicating the translation of the block with respect to the first reference picture; and the processing circuitry is configured to:\n determine the second MV prediction information including a second angular parameter indicating the rotation and a second translation MV indicating the translation of the block with respect to the second reference picture based on the first MV prediction information, the affine prediction mode limited to the rotation and the translation of the block with respect to the first and second reference pictures, and the temporal relationships including a first temporal distance of the current picture from the first reference picture and a second temporal distance of the current picture from the second reference picture.
