Abstract: A method for performing inter-layer prediction when encoding/decoding a video signal, includes confirming, by a decoding apparatus, whether or not only one macroblock of a field macroblock pair of a base layer is coded in intra mode, the field macroblock pair is two vertically adjacent field macroblocks.

A frame macroblock pair is constructed from the field macroblock pair if at least one of the macroblocks the field macroblock pair is coded in the intra mode, and texture prediction information of the current macroblock pair is obtained using texture information of the constructed frame macroblock pair.

Abstract: A method of processing a video signal is disclosed. The present invention includes obtaining a current macroblock type, obtaining skip or direct mode indication information on a partition of the current macroblock according to the current macroblock type, deriving a motion vector of the partition according to the skip or direct mode indication information, and predicting a pixel value of the partition using the motion vector. Accordingly, the present invention obtains a pixel value of a reference block close to an original video using a motion vector, thereby enhancing a reconstruction ratio of the macroblock. As a macroblock uses skip or direct prediction indication information, it is unnecessary to separately code skip mode indication information and direct mode indication information on the macroblock, whereby an information size to be coded can be reduced.
