This sounds like a misdirected attack. There may well be problems in scan- converting American NTSC to European PAL. It does not follow that there will be the same problems scan-converting Japanese HDTV to PAL. In particular, I would assume that moving from a high resolution system to a lower resolution system would make it easier to produce a good quality picture. (NTSC to PAL goes from 525 to 625 lines, requiring things to "stretch".) If anyone knows the technical details of scan conversion artifacts, post it here. -- {sun,ptsfa,lll-crg,ihnp4,ucbvax}!hoptoad!gnu gnu@ingres.berkeley.edu Kudos to Stargate for permitting redistribution.
