Doesn't Channel 4 still use PALplus on analogue terrestrial in the UK? I had one of the rare PALplus compatible TV's sold in Ireland and I seem to remember the Channel 4 picture being noticably better off aerial, and a quick Googling suggests that they used to use it.
Yes, I had one of these TVs in 1998 and the quality was close to HDTV, it was superb.
Whoa?? superb quality??? kidding, right? Not even HDTV 720p looks even close to 1080p. Let alone PalPlus which adds NO extra lines at all. Plain old 576. It's like saying that a 16:9 12" screen looks close to a 20" one.And the ironic thing: most broadcastings in PalPlus look like a plain zoomed 432line 16:9 image with blur in betwee lines - and I'm talking about a 100Hz PalPlus TVset. Why? because they are 432 line images. Even if the system works well (never seen one), most films are already converted to plain 432line 16:9 images, which gain no damn extra 144 lines by magic. In the end, we end with an even poorer image. --217.129.72.168 (talk) 05:02, 4 May 2008 (UTC
Poorer image? I think the key phrase was "never seen one"
Actually, they don't "gain no damn extra 144 lines by magic", they gain those damn extra 144 lines by using the -U phase "helper signal" in the letterbox bars. Obviously if the telecine job on a movie had already been done to only 432 lines, you can't win, but the whole point of PALplus was to transmit material that was originated in 576 lines anamorphic, make it look line 432 lines letterbox to a dumb TV, but allow the recreation of 99% of content of the 576 line image by a smart TV.
