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 12):
An apparatus, comprising processing circuitry configured to:\n decode prediction information of a block of a current picture in a coded video bitstream; determine a motion prediction mode based on the prediction information; determine that the block of the current picture is to be predicted based on multiple reference pictures, the multiple reference pictures including a first reference picture and a second reference picture that are in a video sequence including the current picture; obtain, based on the prediction information, first motion vector (MV) prediction information for the first reference picture; determine 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 the video sequence; and reconstruct a sample in the block based on a first sample in the first reference picture and a second sample in the second reference picture, a first position of the first sample being determined based on the first MV prediction information, and a second position of the second sample being determined based on the second MV prediction information.
