A video signal processing arrangement comprises an input (1) for receiving an input video signal and output (2) at which the processed signal is produced. The arrangement includes a vertical filter (3), a horizontal filter (4), a vertical interpolator (5) a horizontal interpolator (6), a field store

A video signal processing arrangement comprises an input (1) for receiving an input video signal and output (2) at which the processed signal is produced. The arrangement includes a vertical filter (3), a horizontal filter (4), a vertical interpolator (5) a horizontal interpolator (6), a field store (7) and a control circuit (8). The control circuit (8) produces control signals which are fed via paths (20,21,22) to the vertical and horizontal interpolators (5,6) and the field store (7) to re-configure their positions in the signal processing chain in dependence on whether the television picture represented by the input video signal is to be squeezed or zoomed.
