DVD-busters: HD-DVD, Blu-ray discs and EVD
DViant:
Just when you thought that DVD-RWs are good enough they had to develop something newer (again). At least they're ALL backing this one unlike the DVD-whatever mess we're struggling right now.
Blu-ray Disc technology uses blue-violet lasers as opposed to the standard red to achieve a mind-boggling 27GB worth of optical storage space. They're even aiming at stretching it to 30GB for single layer and 50GB for a double layer. This translates to 13hrs worth of MPEG2-quality video as opposed to DVD's 2hrs and 13min limit.
This'll be a boon for people working with uncompressed video.

Here's another article (from TechTV) that reported the agreement on the blue-laser standard that was reached by major electronics manufacturers including Pioneer, Sony and Philips.

Hopefully, blu-ray DVD players will be backward compatible to red laser DVDs.

Hi Dviant!
Thanks for the news and links. They even chose a fortuitous date to announce it - 20.02.2002 or 02/20/2002, a date we won't see again.
This I guess marks the beginning of the end of DVD as we know it, too bad, our current players will not ??? be compatible with this new technology. :'(
With this announcement, we may also begin to see DVD prices going down as manufacturers gear up to take advantage of this format in the next few years and try to get rid of their "to become obsolete" DVD's. ;D
JT:
I don't think it will really make DVD obsolete since it will be using the same format MPEG2. Besides, the current DVD9 disc dual layers capacity are sufficient to hold enough data of a movie. And another thing is that there's DVD18 which is a 4 layered DVD disc if more capacity is required.
robertj:
of course it won't make dvd obsolete. pero with its greater disc capacity, it can hold an entire movie in HDTV quality compared to what we get now from dvd.
