Since you ask twice (and since Matthew didn't mention "interlaced" and my guess may absolutely wrong and since I strongly suspect you have little knowledge about interlaced j2k): Matthew works professionally in digital archiving and I strongly suspect he does know "what it means". > I suggest you combine the 288 line fields to form normal 576 line frames This suggestion would of course make much more sense if you knew what you are talking about. > and then decomb (aka "deinterlace") them. But you have no idea.
