CLAIMS:

1. A method of processing a signal (S) by means of a signal processor (PRC), the method comprising the steps of :
examining (EXAM) the signal (S) to be processed so as to obtain a distortion indication (END) indicating to which extent distortion (DIST) would be introduced if the signal (S) were processed (PRC[S]) by means of the processor (PRC);
pre-processing (FLL) the signal (S) in dependence on the distortion indication (LND) so as to obtain a pre-processed signal (SF); and
processing (PRC[SF]) the pre-processed signal (SF) by means of the processor (PRC).

2. A signal-processing arrangement comprising a signal processor (PRC), characterized in that the signal-processing arrangement further comprises:
an examining circuit (EXAM) for examining a signal (S) to be processed so as to obtain a distortion indication (END) indicating to which extent distortion (DIST) would be introduced if the signal (S) were processed (PRC[S]) by means of the processor (PRC);
a pre-processor (FLL) for pre-processor the signal (S) in dependence on the distortion indication (END) so as to obtain a pre-processed signal (SF), the signal processor (PRC) being coupled to the pre-processor (FLL) for processing (PRC[SF]) the pre-processed signal (SF).

3. A signal-processing arrangement as claimed in claim 2 characterized in that the pre-processor (FIL) comprises an adjustable filter whose filter characteristics are adjusted in dependence on the distortion indication (END).

4. A method of video encoding comprising the steps of:
examining (PENC) video data to be encoded so as to obtain a complexity indication (CI) indicating how difficult it is to encode the video data;
filtering (FEL) the video data in dependence on the complexity indication (CI) so as to obtain filtered video data; and
encoding (ENC) the filtered video data.

5. A video-encoding arrangement comprising:
- an examining circuit (FEL) for examining video data to be encoded so as to obtain a complexity indication (CI) indicating how difficult it is to encode the video data; an adjustable filter (FTL) for filtering the video data in dependence on the complexity indication (CI) so as to obtain filtered video data; and
a video encoder (ENC) for encoding the filtered video data.
