Abstract: The present invention relates to an entropy encoding method, an entropy decoding method and to an apparatus using same. The entropy decoding method includes: a step of decoding a bin of a syntax element; and a step of acquiring information on the syntax element based on the decoded bin. In the step of decoding the bin, context-based decoding or bypass decoding is performed for each bin of the syntax element.

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.
