In a video processing system having an intra-field processing mode which allows a better luminance-chrominance separation, and an inter-field processing mode which allows a better performance in the presence of motion in the color signals, wherein a motion-dependent choice is made between these modes, chrominance-difference signals (Ud, Vd) are derived from chrominance signals (U, V), and a first linear combination of the chrominance-difference signals (Ud', Vd) is derived when the V chrominance-difference signal (Vd) exceeds the U chrominance-difference signal (Ud'), and a second linear combination of the chrominance-difference signals (Ud', Vd) is derived in the opposite case, to obtain a motion signal (M) for the motion-dependent choice.

Video processing system featuring a choice between inter and intra field

A document and image processing system, used for the updating of document-wise organized information an office system, has a number of auxiliary apparatus for recording, filing and outputting of such information. Also present are a processor with terminals, peripheral apparatus and a data bus. For the fast execution of mass data transport between the auxiliary apparatus there is provided a switching device which has a number of parallel data highways. Each auxiliary apparatus is connected to the switching module by means of its own switching module in order to be interconnected to either the data bus or, via one of the data highways, to another auxiliary apparatus.
