Hi Jeroen, nice to hear from you ! > I think that its popularity in France and in Eastern Europe > was mainly due to its incompatibility with the West-German > PAL system, and due to the not-invented-here syndrome. > Now with DVB the united Europe looks a lot better. :-) In France, the "invented here" syndrom certainly played a role, even though it was just a variation on NTSC (but then you could say part of NTSC also used the french patents of Georges Valensi), and the color CRT was really an american thing. But it did not hurt it could give good reliable pictures, and i am rather satisfied with the service it has provided to me during all these years. As for video standards compatibility the most important step was alignment on 625/50 scanning format, IMHO. Can't dispute the fact a DVB europe looks better. I regret the trend is not to also use it for radio, especially now that we have DVB-T2 Lite. > Europe should have > adopted the simpler NTSC method of color modulation, and > solve the hue (color tint) problem in a different way. > Do you have something in mind for this different way ? > BTW, the hue problem should not have existed in the first > place.

Transmission does not play a role? There really is a safe margin everywhere when using semiconductors? I would feel a bit nervous using a standard that relies on good behavior of all the components in the transmission chain for such a subtle point, and cannot compensate for the problem if it occurs. Isn't it true that many modern NTSC sets still include an automatic skin tone correction ? There were discussions on a french forum with a canadian guy that has moved a lot and lived under the three standards at one time or another. He experimented from the Montreal island (circa 2006, i believe). He said that by playing with the settings, he could get a nice picture from Radio-Canada, but when turning to american broadcasts (all by air) from ABC, NBC, CBS, chromatic accuracy was degraded, and it was not possible to compensate with the settings in a completely satisfying way. Also, it was different from channel to channel. So, i have my doubts that the problem was completely solved by switching to semiconductors. And even when the first color broadcasts started in Europe (and more so during the design phase) the era of fully transitorized sets was not yet there, so it is really only with hindsight that we can revisit those choices. ---------------------------------------------------------------------- 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.
