Abstract
A television standards converter comprises a motion analyzer for analyzing the motion between consecutive fields of an input television signal of one television standard and for deriving motion vectors in dependence on the motion, a filter for recursively filtering the motion vectors, and an interpolator for aligning the fields in dependence on the filtered motion vectors so as effectively to represent static pictures, and means to effect conversion using the static pictures to derive the required output television signal of a different television standard.
