<p>Video coding and decoding methods capable of providing motion scalability and video encoder and decoder are provided. The video coding method includes estimating a base layer motion vector and an enhancement layer motion vector for each block in a video frame, removing temporal redundancies in the video frame using the enhancement layer motion vectors, spatially transforming the video frame in which the temporal redundancies have been removed and quantizing the spatially transformed video frame to obtain texture information, selecting one of the estimated base layer motion vector and the estimated enhancement layer motion vector for each block, and generating a bitstream containing the motion vector selected for each block and the texture information.</p> |
