    • A movement detector for detecting movement in a television picture comprises a local movement detector which produces an output signal as a result of comparing similar input signals from different fields and the detector output signal is processed in a field store processor which spreads the output signal in space and in time. The processor comprises a recursive loop, a field delay element and a look-up table, with the latter receiving as inputs the output from the recursive loop and the instantaneous input to the processor to produce a control signal output. A line interlace to non-interlace transformation circuit including such a movement detector is also disclosed.

    • Chrominance component signals of two different types are produced such that the chrominance signals alternate within a field and between adjacent fields in order to provide an improved amount of information from which to enhance the vertical chrominance resolution of a television receiver. The appropriate chrominance structure is either provided by a special source or else a conventional source is filtered in order to produce the appropriate structure. The filter comprises two portions, one for filtering chrominance signals of a first type from a first field and one for filtering chrominance signals of a second type from the first field in order to provide interpolated signals. A specific filter structure is disclosed which may be used for either pre- or post-filtering.
