Simple Q : Is R2 PAL DVDs High Def or not.
I think HD is 720p and above.
Thanks Timmy B but can dvds put out up to 720p or is less than this.
Sorry, PAL has 525 lines. NTSC is 480. I think HD is 720p and above.
A dvd player or scaler can scale PAL to HD.
Is there any difference in picture quality between scaling up to 720p or converting down to 480p. 520 lines is closer to 480 than 720. I think you know where I`m going with this.
Depends if your display is HD. If it is, then 720 would be best, if an ED display, I would also use 720 and let the display scale to 480p when using PAL discs (for ntsc just use 480p out). You wont miss much scaling PAL to 480p - on the american avsforums most will agree that at 8 feet back, you can't tell the difference between ED and HD.
If this is the case is it better to view PAL dvds on a ED or HD screen?
HD all things being equal.
It wont matter if your viewing distance is more than 8 feet away though. Resolution is just one link in a long chain...
PAL is 625 horizontal lines. 576 of which are visisble usually.
NTSC is 525 horizontal lines, 480 of which are usually visible.
HDTV is a whole pile of stuff. 720P up t0 1080P.
As TimmyB says there are a whole host of other things apart from the maount of pixels available that can contribute to picture quality.
When purchasing a product just now though you may want to consider how long you intend to keep it. You may find that in not so long a period we will have HD cources in this country, or you might want to view PC through your monitor. In that case a SD plasma might not be so useful.
Usefull US FAQ on HDTV. However it is US based so no PAL mentioned
As Gordon stated though 576 lines from total of 625 are used for actual picture within PAL sources, this is standard defintion.
Whether or not PAL looks better on SD or HD displays will be dependant, amongst other factors, upon the quality of scaling - either up or down that is involved.
However, with any downscaling you are loosing intended picture information (detail). As stated whether or not this is important will be subjective with SD sources, though more of a factor/issue with HD sources.
Now that you can get PAL 576 rez. based projector DLP panels why havn't 576 plasma been made for the European market ? (or have they ?)
