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.
