Abstract
The present invention relates to a method for conducting interlayer motion prediction in encoding or decoding of video signal. The present method sets motion information of an intra-mode macro block of a base layer with motion information of an inter-mode macro block that is vertically adjacent to the intra-mode macro block, derives motion information of a pair of macro blocks adjacent vertically each other from the two macro blocks, and uses the pair of macro blocks in inter-layer motion prediction.
Claims10
A method for encoding or decoding a video signal, the method comprising:
- setting motion of an intra-mode macroblock to motion information of an inter-mode macroblock, the intra-mode and inter-mode macroblocks being two vertically adjacent macroblocks of a base layer;
- and
- deriving motion information of a pair of vertically adjacent macroblocks for interlayer motion prediction based on the two vertically adjacent macroblocks of the base layer.
The method according to claim 8, wherein the pair of vertically adjacent macroblocks for use in interlayer motion prediction is a pair of macroblocks of a field component image.
