Abstract
A signal processing system 20 comprises a source 22 of video signals representing pixels in a first format (e.g. 4:4:4). The video signals are coarsely processed by a filter 43 and interpolator 44 and the processed signals are compared by a comparator 46 with the video signals. Depending on the result of the comparison either signals from the filter 43 or signals from a filter 30 are selected for output as video signals representing the pixels in a second format (e.g. 4:2:2).
