Inter-Layer Prediction Method for Video Signal
First Claim
1. A method for encoding or decoding a video signal, the method comprising:
- a) constructing a pair of frame macroblocks from a pair of vertically adjacent field macroblocks included in the interlaced video signal;
b) separating a video signal including the pair of frame macroblocks into even and odd field components;
c) interpolating each of the even and odd field components in a vertical and/or horizontal direction; and
d) obtaining a reference image by using the interpolated even and odd field components.

Abstract
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.
