INTER-LAYER PREDICTION METHOD FOR VIDEO SIGNAL

摘要

The present invention relates to a method for using interlaced video signal of a base layer in interlayer texture prediction. The present method constructs a pair of frame macro blocks from vertically-adjacent two field macro blocks pertaining to interlaced video signal of a base layer, separates video signal containing the pair of frame macro blocks into even- field and odd- field components, interpolates the even- field and the odd- field components respectively in vertical and/or horizontal direction, and constructs a combined video data by interleaving the interpolated even-field and odd-field components.
