Abstract (en)

[origin: WO2006004305A1] An apparatus and method for improving the multi-layered motion vector compression efficiency of a video coding method by efficiently predicting a motion vector in an enhancement layer from a motion vector in a base layer. The apparatus includes a base layer determining module that determines motion vector component of a base layer having the base layer pixel accuracy using the obtained motion vector, and an enhancement layer determining module that determines a motion vector component of an enhancement layer having the enhancement layer pixel accuracy which is obtained motion vector.
