1. A method for encoding or decoding a video signal, the method comprising the steps of:

  • confirming whether or not at least one of two vertically adjacent macroblocks of a base layer is of intra mode;

    copying, if it is confirmed that only one of the two macroblocks is of intra mode, motion information of an inter-mode macroblock included in the two macroblocks to the intra-mode macroblock to set the intra-mode macroblock to a block having motion information; and

    constructing a pair of frame macroblocks from the two macroblocks if the two macroblocks are all intra-mode field macroblocks.
