Quote from Joe Kane, godfather of video
“……..It is often accomplished by converting the incoming component signal to S-Video, then sending that signal to their standard decoder chip. Believe it or not, this is a common practice, not only among TV set manufacturers, but in several video upconverters. There is a picture quality loss going from component to S-Video then back to component inside the old processor chip. This is usually what’s going on in the video system when reviewers proclaim S-Video equal to component video.”
Now I have ‘researched’ this subject more I am of the opinion that this is common practice at the very least. I am also VERY suspicious that some may even process in composite. And you all thought it was simple……
As I said before, buyer beware or at least be educated. It may well be that all the high resolutions signals (component / RGB) get down converted to S Video (or composite?) internally and the differences we see are down to engineering and connectors. Poor old Scart…..The more I look into this subject the worse it gets.
The Snell & Wilcox Zone Plate test pattern on Video Essentials will help people investigate this further if they are as sad as me.
