Our eyes clearly do not deceive us; when visiting Europe we do see an obviously superior analog television picture. However, PAL is not the source of this superiority. The reality is that PAL actually somewhat degrades the overall image quality and the problem it was designed to resolve (Color TV set Hue inconsistencies) was resolved by TV set manufacturers over twenty years ago . The source of this superior "PAL" picture is actually the additional 25% bandwidth allocated to that signal and an additional 100 vertical scan lines used per frame. If Europe were today transmitting NTSC with those same parameters we would see at least as good a picture as we do with PAL. ---------------------------------------------------------------------- You can UNSUBSCRIBE from the OpenDTV list in two ways: - Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org - By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
