The FMH filter concept for video signal processing which combines the features of linear and median filters is introduced. In FMH (FIR median hybrid) filters, the overall output is the median calculated over the outputs of FIR subfilters, and the central input sample, the number of values to be sorted, is independent of the filter size; only the size of the FIR subfilters is altered. The noise reduction properties of FMH filters are similar to those of median filters. Applications within the field of digital enhanced TV, EDTV, and HDTV are presented with emphasis on noise suppression and image coding.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
