    • 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. The present invention includes obtaining a macroblock type, checking whether a macroblock includes a intra prediction coded sub-macroblock and a inter prediction coded sub-macroblock when a macroblock includes a plurality of coded sub-macroblocks according the macroblock type, when the macroblock includes the ultra prediction coded sub-macroblock and the inter prediction coded sub-macroblock, obtaining prediction mode flag information indicating whether the sub-macroblock is the intra prediction coded or the inter prediction coded, when the sub-macroblock is the intra prediction coded based on the prediction mode flag information, obtaining prediction direction information from a block adjacent to the sub-macroblock and a prediction value of the sub-macroblock based on the prediction direction information, and when the sub-macroblock is inter prediction coded based on the prediction mode flag information, obtaining motion information from the block adjacent to the sub-macroblock and a prediction value of the sub-macroblock based on the motion information. Accordingly, the present invention is able to raise coding efficiency of video signal by adding an intra prediction mode as a sub-macroblock in predicting a macroblock.
    • 本发明涉及用于将帧内预测模式作为子宏块类型添加到对编码视频信号的宏块进行预测的视频信号解码方法。 本发明包括:当宏块包括宏块类型时,当宏块包括多个编码子宏块时,获得宏块类型,检查宏块是否包括帧内预测编码子宏块和帧间预测编码子宏块 超预测编码子宏块和帧间预测编码子宏块,当子宏块是基于该预测编码的子宏块的帧内预测编码时,获得表示子宏块是帧内预测编码还是帧间预测编码的预测模式标志信息 预测模式标志信息,从与子宏块相邻的块获得预测方向信息和基于预测方向信息的子宏块的预测值,以及当子宏块基于预测模式标志进行帧间预测编码时 信息,从与子宏块相邻的块获得运动信息,以及a 基于运动信息的子宏块的预测值。 因此,本发明能够通过在预测宏块中添加帧内预测模式作为子宏块来提高视频信号的编码效率。
