ABSTRACT:
In an arrangement for processing video signals provided as interlaced video signals generated in the interlaced scanning mode, in which two fields constitute one frame, and/or as pseudo-interlaced video signals derived from non-interlaced video signals obtained by means of progressive scanning, flexible use of the arrangement with a minimal number of components for this arrangement is achieved in that at least one video signal-processing unit (1) is provided which receives at least an interlaced video signal or at least a pseudo-interlaced video signal and processes these video signals in dependence upon control data generated by means of a control unit (2), and in that a clock generator (4) is provided which controls the control unit (2) and/or the video signal-processing unit (1) in such a way that, when processing an interlaced video signal or a pseudo-interlaced video signal, possibly new control data are generated and/or taken into account as from the start of its next field or its next frame, respectively.
