I guess these deblockers are uncommon in existing DTVs, though? Or are they not very effective? Seems like it shouldn't be an impossible task. And momentarily making a very fast-moving part of the image less sharply defined is something that human vision shouldn't mind so much, IMO. Possibly too, this is one of those problem areas that the expertise of cameramen will have to accommodate, sort of like judder in movies.
