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