Hi-Def DVDs? - DVDfile.com forum for DVD, Blu-Ray, and HD-DVD

svtcontour · 11-12-2001, 06:54 AM

Has anyone who regularly scours mags like Widescreen Review and so on heard any news about the availability of Hi-def DVD's in the coming couple of years? You would think this would be the perfect delivery medium for it: built-in enthusiast audience, controlled delivery medium, etc. I find it difficult to believe that if you used a Diode-pumped solid state (DPSS) green laser at 532 nanometers, and a couple of DVD-18 discs (all technology currently available) that you couldn't get enough room for 720P or 1080I. Is anyone else with me here in just dying for Hi-def DVDs? I think most transfers nowadays are actually being done in Hi-def, and then just downconverted for NTSC. Are there obstacles here I'm not aware of here in getting something like this off the ground?

Well, it's all about space.

NTSC: 720x480 = 345600 pixels of information

HD: 1920x1080 = 2073600 pixels of information

So HD has 6 times as much information. So for HD DVD's, you'd need something that holds rougly 54GB per side for a standard movie. The question is, does anybody have a reasonable, afforadble, workable hardware solution for that?

There's the math I needed... thank you! Now I can at least look at storage with a critical eye towards those size targets.

its crap!!!! Hi-DEF DVD uses a blue laser and is not compatable with current DVDs. However FMV(?) Disc should be playable on DVD players and hold around 400 Gigs of info and have 100 layer changes. Best of all they are red laser read discs!!!

I didn't even think there was a Hi-DEF DVD standard yet.
