ABSTRACT:
In motion compensated standards conversion, an output video field is constructed from four input fields (two inner fields and two outer fields) by shifting pixel information from an outer field to the output field position in two stages, the first stage using a first motion vector between the outer field and the adjacent inner field and the second stage using a second motion vector being derived from a motion vector pointing from one inner field to the other inner field.
