1. A method for performing inter-layer prediction by a tangible decoding apparatus when encoding/decoding a video signal, comprising:

  • confirming, by the decoding apparatus, whether or not at least one macroblock of a field macroblock pair of a base layer is coded in intra mode, the field macroblock pair being two vertically adjacent field macroblocks;

    predicting, by the decoding apparatus, motion information of a current macroblock pair in an enhanced layer using motion information of an inter-mode macroblock in the field macroblock pair when the confirming confirms that only one of the macroblocks in the field macroblock pair is coded in the intra mode;

    constructing, by the decoding apparatus, a frame macroblock pair from the field macroblock pair when the confirming confirms that the macroblocks of the field macroblock pair are coded in the intra mode; and

    obtaining, by the decoding apparatus, texture prediction information of the current macroblock pair using texture information of the constructed frame macroblock pair.
