INTER-LAYER PREDICTION METHOD FOR VIDEO SIGNAL

摘要

The present invention relates to a method for conducting interlayer motion prediction in encoding or decoding of video signal . The present method checks whether at least one of vertically-adjacent two macro blocks on a base layer is intra mode, and if only one of the two macro blocks is identified to intra mode, motion information of an inter-mode macro block of the two macro blocks is copied to the other intra-mode macro block in order to set the intra-mode macro block to a macro block having motion information.
