    Abstract: A method for processing a video signal using an affine motion prediction is disclosed. The method includes checking that a current block is encoded by the affine motion prediction, obtaining motion vectors for a plurality of control points of the current block, determining a motion vector for each of a plurality of subblocks included in the current block based on the motion vectors for the plurality of control points, and performing a prediction for the current block from the motion vector for each of the plurality of subblocks, wherein each of the plurality of subblocks is configured to have a pre-defined width and a pre-defined height.

    Abstract: The present invention relates to a method for performing entropy decoding on a video signal including a current block. The method comprises the steps of: deriving affine coding information and/or affine prediction mode information of a left block and/or an upper block which are adjacent to the current block; determining a context index of a syntax element associated with an affine prediction of the current block on the basis of at least one of the affine coding information and/or the affine prediction mode information of the left block and/or the upper block; and entropy decoding the syntax element associated with the affine prediction of the current block on the basis of the context index.

    Abstract: A displace device for a vehicle includes a display unit and a controller. The controller is configured to: receive an image of a road in which the vehicle is located and trajectory information providing a trajectory of vehicle movement, detect one or more lanes of the road based on the received image of the road, assign weights to (i) the detected one or more lanes and (ii) the trajectory of vehicle movement, respectively, based on a preset reference value, generate a virtual road image providing a direction based on the assigned weights, and control the display unit to display the generated virtual road image.
