Abstract: The present invention relates to a video signal decoding method for adding an intra prediction mode as a sub-macroblock type to prediction of a macroblock in coding a video signal. Some implementations may include obtaining a macroblock type, when a macroblock includes the intra prediction coded sub-macroblock and the inter prediction coded sub-macroblock based on the macroblock type, obtaining prediction mode flag information indicating whether the sub-macroblock is the intra prediction coded or the inter prediction coded, and obtaining a prediction value of the sub-macroblock. Accordingly, implementations disclosed herein may raise coding efficiency of video signal by adding an intra prediction mode as a sub-macroblock type in predicting a macroblock.

Abstract: In one embodiment, the method includes determining a motion vector of a current image block equal to a motion vector of an image block based on a reference picture index indicating a reference picture for the image block. For example, the motion vector of the current image block may be equal to the motion vector of the image block if the reference picture index indicates a long-term reference picture for the image block.
