Industry Agrees On Next Gen Unified DVD Standard

scsirob writes "According to this press release the DVD recording industry will end the DVD-RW/DVD+RW/DVD-RAM mess and standardise on a new technology called 'Blue Ray'. Blue lasers are used to record up to 27 GB on each side of the DVD. This initiative is backed by all major players in the industry. The article contains many technical details." Several other people noted that the BBC has coverage as well. Yah for non-company specific industry standards.

These could be excellent backup devices.

Provided there is ever a way to record these on your own like a regular CD (without spending thousands, that is), these could be excellent for archival purposes.

Currently, my only solution for backups of my drives are other drives. Sure, tapes work, but they take far too long. Being able to dump the essentials from my hard drive (being a 3D designer, that's easily 30 gigs of textures, models, etc) onto one disc would be a lifesaver.

Let's just hope these things aren't so crippled by the time we get them that their apparent benefits aren't overshadowed by idiotic "protection" schemes.

Re:Just mpeg-2?

[TechnoVooDooDaddy]

i'm finding it a common misperception that mpeg-4 is automatically assumed to be "better" than mpeg-2. mpeg-2 works really well in situations where broadcast quality (or better) video is needed, and space isn't necessarily a limiting factor. A bitrate of 4mb per second and judicious use of the AFF (advanced field frame) tech will get you amazing quality video and sound. Mpeg-4 comes into it's own and is useful in situations where space is an issue. 27G (per side?) is more than enough for a movie, or two... with a lot of extras thrown in.

as my daddy use to say, if it ain't broke, don't fix it.

Digital Rights Management is present

[kris_lang]

Actually, the press release directly addresses the issue of Digital Rights Management. To quote:

"It is possible for the Blu-ray Disc to record digital high definition broadcasting while maintaining high quality and other data simultaneously with video data if they are received together. In addition, the adoption of a unique ID written on a Blu-ray Disc realizes high quality copyright protection functions."

This is positive news ...

For those who bought either DVD-R(W) or DVD+RW nothing changes. Todays players (standalone and DVD-ROMs) can play your discs fine. DVD-R plays everywhere, I have found no player, where it doesn't work.

To the future: This new format is a next generation format. 27GB per layer is a very cool capacity. Combined with MPEG2 and AC3 whole seasons of 'startrek' may be on one disc. But on the other hand: have you looked at the sizes of DVDs lately: they are big like nearly 9GB. Viewed at 27GB from this side it's actually small. It's the bare minimum ;-)

The physical problems with DVDs are scratches. The more capacity there is on the disc the more problems you get.

What I like about this announcement is that all major players are on the list, this is positive: nobody will have choose the "better" format, this is also the negative thing ;-) They will have full world-wide control over the format, things like region-protection will probably be better enforced, because of their monopoly in the market.

To those who need DVD-R right now, nothing has changed, buy a player, I've seen discs as cheap as $3 ;-) And the DVR-A-03 is very cheap too.

For those who want a DVD-video recorder: WAIT for this new format, this will really enhance the VCR experiance: direct access and capacity ...

It'll have next-gen CSS

[yerricde]

From the article:

In addition, the adoption of a unique ID written on a Blu-ray Disc realizes high quality copyright protection functions.

I assume this to mean that it'll employ the next generation of CSS encryption. For one thing, MPAA and friends have probably learned their lesson: don't roll your own stream cipher. For another, it's now legal to export products using 128-bit encryption from the United States; the regulations in effect when DVD CSS was standardized permitted only 40-bit.

Or is this just a try to make movies even LARGER so cable and DSL users can't share movies in high quality anymore?

At a point, the detail becomes so fine that the human eye can't distinguish it. XviD (a fork of the last free DivX 4 release) attempts to find that point.
