ABSTRACT
A method for padding interlaced texture information on a reference VOP to perform a motion estimation detects Whether said each texture macroblock of the reference VOP is a boundary block or not. After the unde?ned texture pixels of
the boundary block are extrapolated from the de?ned texture
pixels thereof by using a horizontal repetitive padding, a (51) (52)
