Abstract

A two-dimensional filter operates in accordance with a three-dimensional television signal having a basic layer, a reference processing unit layer and an enhancement layer. The two-dimensional filter generates a processed base layer reference picture from a base layer reference picture via a one-dimensional horizontal filter that horizontally filters the base layer reference picture to generate a first filtered base layer reference picture and a one-dimensional vertical filter, coupled to, but separable from, the one-dimensional horizontal filter, that vertically filters the first filtered base layer reference picture to generate a pre-processed base layer reference picture.
