Abstract: In one embodiment, a method of predicting a motion vector for a current block in a current picture by a moving picture decoding device includes obtaining, by the moving picture decoding device, a direction of a reference picture of the current picture, based on comparison of a display order of the reference picture and a display order of the current picture, obtaining, by the moving picture decoding device, at least three forward motion vectors for at least three other blocks than the current block based on the direction of the reference picture, and predicting, by the moving picture decoding device, a forward motion vector for the current block by using median operation of the at least three forward motion vectors.

Abstract: A method of processing a video signal is disclosed. The present invention includes receiving prediction information of a macroblock and filter information, predicting a current picture using the prediction information of the macroblock, and applying a filter using the predicted current picture and the filter information.Accordingly, accuracy of prediction can be enhanced by applying a filter to a frame predicted before a residual for a predicted frame is coded. As the residual is reduced, efficiency of video signal processing can be enhanced.
