Description

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 an interpolator operative to align the fields pixel by pixel in dependence on the analyzed motion so as effectively to represent static pictures, and to effect conversion using said static pictures to derive the required output television signal of a different television standard. A slow motion processor using basically the same circuitry operates in a similar way.
