Blu-Ray Vs. DVD

[PC-Engine]

And I find it funny that some would resort to calling those that buy UMDs as geeks when they are also talking in other threads about building HTPCs for $400 with an all aluminium case, remote, and HD-DVD drive.

Difference is HD DVD is compatible with DVD, CD. UMD movies arent compatible with DVDs...heck they're not even compatible with tvs.

Thanks Ty for the good post, but this has to be locked. Everybody has made a great point about UMD and Blu-ray but some people (or person) can't let go of his or her hate for Sony.

Well if you don't have a valid argument then maybe you should stop complaining, because frankly your complaining is annoying. I'd rather much listen to KZ is teh reelztyme...

I was just saying that you are trying to marginalize UMD purchasers as niche but then making HTPC-building as comparable to mass market when it clearly is niche as well.

I never said HTPC is a mass market. I said DVD drives in PCs are which will be the same case for HD DVD drives. HTPCs is one product that fit into this category. It doesn't make up the category.

Yes, eventually HD-DVD or BR drives in PC will be as common place as it is today.

Well more than likely it will be Blu-ray.

March 10, 2005—The Blu-ray Disc Association (BDA) today announced that Apple® will become a member of the consortium’s Board of Directors. Apple has been a leader in driving consumer adoption of DVD authoring since January 2001, with the introduction of its SuperDrive™.

“Apple is pleased to join the Blu-ray Disc Association board as part of our efforts to drive consumer adoption of HD,†said Steve Jobs, Apple’s CEO. “Consumers are already creating stunning HD content with Apple’s leading video editing applications like iMovie HD and are anxiously awaiting a way to burn their own high def DVDs.â€

“Apple has a long history of technical innovation around DVD hardware and software, and their support of the Blu-ray Disc format is a testament to their commitment of ongoing innovation. The Blu-ray Disc format provides the immense capacity and the revolutionary functionality that Apple’s loyal customer base will be sure to enjoy,†said Maureen Weber, chief BDA spokesperson and general manager of HP's Optical Storage Solutions Business. “We’re thrilled about Apple joining our 16-member board, and we look forward to working with them on the development and promotion of the Blu-ray Disc format.â€

HP and Dell, have joined the Blu-ray Disc Founders (BDF), adding support from the world's two largest PC manufacturers to the already broad support from the consumer electronics industry for the Blu-ray Disc format.

HP today announced that they will start selling PCs equipped with Blu-ray Disc drives in late 2005, starting in its desktop PCs, media center PCs, personal workstations, and digital entertainment centers. "Our decision to back Blu-ray was largely because of its capacity advantage (over HD-DVD), as well as the interactive features being built into the specification." said Maureen Weber, general manager of optical storage at HP. Pushing products based on Blu-ray to market is a priority for HP. "The arrival of high-definition content in the home, along with the convergence of PCs and home entertainment, has created a need for a higher capacity optical disc format." said John Romano, senior vice president, Global Consumer PC Business, HP. The drives are expected to be backward compatible with CD/DVD, and to support read-only, recordable and rewritable Blu-ray Discs. HP also plans to introduce Blu-ray Disc drives in notebooks in early 2006.

Blu-ray media to be priced in line with DVDs

Blu-ray media to be priced in line with DVDs

Isn't this what they've been saying all along but can't provide any evidence?

*YAWN*

You people are still arguing over something that we have to wait for to see how it turns out?!

 

[Diplo]

I wonder how resilient to damage that Blu-Ray media will be? As you increase density on a disc then you also dramatically increase the chance of it being irreperably damaged by the tiniest of scratches or even fleks of dust or greasy fingerprints. This doesn't matter massively for movies because a few misread bytes (that can't be corrected by error-checking) will only cause a second of blockiness on screen, but a few misread bytes in game code mean it crashes and doesn't work.

Does anyone know how Sony intend to cope with this problem?

All BRDs are required to have a hardcoating to protect it form scratches, dust, dirt, etc. They originally had a caddie for the discs, but later switched to a hard coating due to the fact consumers are not very fond of caddies.

 

[mckmas8808]

Debate is now over. Its starting to become offical. Blu-ray is the future. Thank you.

Video, video, video...

What about a boatload of uncompressed DTS 5/6.1 audio - a technology that's probably more prevalent in homes than HD and a BR standard? This is what I personally consider the highlight of BR.

As was said previously - give this to Monolith - they can fill it up with audio for 8 hours of Xenosaga III cutscenes. (for reference the scarface DTS track was aroun 900MB).

That's why there's something like 24x redundancy isn't it? The data's repeasted 24x so if one byte on one copy is bust, it can be read from another copy of the data.

Don't knw the exact numbers, but certainly CDs hold something stupidly large like 20x the amount of data on them because it's duplicated so much to overcome data problems.

Are you serious? I have never heard about that. And i know a lot of stuff.

 

[wco81]

Supposedly, the demo they gave of the TDK hard coat involved trying to gouge the data side with a pen and being unable to and then writing over it with a Sharpie marker and having the ink bead up and being able to wipe it off.

So the hard coat seems to be for real but the question is how much it adds to the cost of the discs. Blu-Ray already had questions about how competitive its replication costs would be.

I'm serioues, though maybe very wrong I remember being gobsmacked how much really data was on a CD, but it's all redundancy (we hear a lot about that these days...) to make sure data's restorable.

A quick Google didn't turn up anything of the sort, only a 14 bits to 8 bits of data for error correction. And with no idea where I first read about the CD data thing (a computer magazine I think, like PCPro or Comuter Shopper) I guess we'll never know for sure...

 

[PC-Engine]

Regarding the hardcoat, there are many different versions of this hardcoat. The expensive and timely version is the one that was demoed. Other cheaper versions will not exhibit the same kind of durability as the demo.

Oh and I want to clarify that the hardcoat is not mandatory, it's only assummed to be for prerecorded content. Recordable BRDs may opt to use a caddie instead.
