<p>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 reconfigure 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.</p> |
