    摘要: A video encoder s configured to encode a bitstream to be decoded by a compatible decoder, the bitstream including a coded picture with a first region with a first contiguous plurality of coded blocks and signaling information associated with each coded block. For each coded block in the first region, in response to the associated signaling information, the decoder receiving the bitstream constructs a motion vector candidate list including a motion vector candidate enabling the reconstruction of global motion in the first region. If the motion vector candidate is a translational motion vector, the decoder decodes the blocks in the first region using translational motion compensation to reconstruct global motion in the first region. If the one motion vector candidate comprises multiple control point motion vectors, the decoder uses affine motion compensation to reconstruct global motion in the first region.
