128GB BDXL Blu-ray disc specification finalized… and fabulous!

admin — Fri, 25 Jun 2010 14:57:00 +0000

Looks like the Blu-ray Disc Association has published the final specs for the monster BDXL disc, opening the way for manufacturers to start introducing the technology in their optical drives. Not too much here that we don't already know: aimed at institutions and folks who need to archive lots and lots of... stuff, BDXL discs are available in either triple layer 100GB (re-writable or write-once) or 128GB quad layer write-once flavors. Of course, with all these layers (or layuhs in Brooklyn) the laser in the Blu-ray drive you already own won't be able to do the trick, so start saving your change for a hardware upgrade once these things become commercially available. PR after the break.

Blu-ray Discs expand to 128GB under new BDXL spec

admin — Sat, 03 Apr 2010 15:41:00 +0000

This probably isn't a response to the 3D onslaught or even "superbit" releases like the upcoming Avatar 2D disc, but just in case the standard 50GB Blu-ray discs were beginning to feel a bit -- how do you say... cramped? -- the Blu-ray Disc Association's rolling out a new BDXL format capable of holding up to 128GB (write-once) or 100GB (rewriteable). Before you get too excited, you should know that you'll need a new player to access these -- even a firmware update won't save the PS3 this time -- since they go up to three or four layers deep and will likely need a more powerful laser. While our home movies can be compressed just fine, corporations currently still using other mediums for archiving might appreciate the extra space, as well as the new IH-BD discs, designed with one 25GB read-only layer, and one 25GB rewritable layer on the same platter. If you're looking for a place to permanently back up that super high-res "amateur photography," take heart -- a consumer version is in the works, though it will first be aimed at markets where Blu-ray Disc recorders are popular, or available at all (read: maybe Japan, definitely not the US). No word when the new hardware will actually hit the market, but final specs are due "in the next few months." In the meantime, check out the full details after the break.

Blu-ray’s 3D spec isn’t what it could be

admin — Fri, 08 Jan 2010 06:46:00 +0000

While 3D is all the rage at CES this year, we learned today from the BDA that one of the biggest sources of 3D content isn't what it could be. The first thing that could, should, be better is the limited support for frame rates. Movies have been recorded at 24 frames per second for longer than our parents have been alive, and for about the same amount of time we've had to endure frame rate interpolation to make movies play back on our 30Hz TVs -- you know, like 3:2 pull-down. That changed recently with 120hz LCDs and 72Hz plasmas because those numbers share a common denominator with 24 (so the same frame is just shown three or four times). Well so much for that because the frame rates of the new 3D displays don't share a common denominator any more (either 30 or 60 hz per eye) -- admittedly this can change. But honestly the worst part is that some 3D cameras can capture 3D at higher frame rates and even if the director wanted to, the new 3D Blu-ray spec doesn't support it. The other issue we take with the new spec is that contrary to early reports, it is possible to create a 3D Blu-ray Disc that won't play on 2D only players. This next one isn't a big deal, but still disappointing is that even if the creator goes through the trouble to encode the movie in both formats, depending on the 3D player, you may have no choice but to watch it in 3D -- say if you lost your glasses or whatever. Now don't get us wrong we're pretty excited about the new 3D technology, but the way we see it is that anything worth doing, is worth doing right the first time.

New standard could pave way for higher capacity Blu-ray discs

admin — Sat, 02 Jan 2010 15:27:00 +0000

Already feeling the pinch of a mere 25GB per layer on a Blu-ray disc? Neither are we, but it looks like Sony and Panasonic have been busily working on ways to boost capacity nonetheless, and they've now devised a new method that seems to be on the fast track to becoming a standard. The best news is that it doesn't involve a change in Blu-ray optics, but rather something called the Maximum Likelihood Sequence Estimation evaluation index (or i-MLSE -- the "i' is just for kicks, it seems), which is a new means of estimating the read error rate of discs on the fly that has apparently be made possible thanks to "recent hardware advancements." According to Sony and Panasonic, that should now allow discs to hold up to 33.4 GB per layer, but it's not exactly clear what that means for existing Blu-ray players (a little firmware assistance seems to at least be a conceivable option, though). There's also no timeline for a rollout just yet, but Sony is reportedly now set to propose widespread adoption of i-MLSE to the Blu-ray Disc Association, of which it just so happens to be the leading member.

Toshiba applies for BDA admission, Blu-ray players and laptops coming soon

admin — Mon, 10 Aug 2009 08:20:00 +0000

We'd already heard that Toshiba -- the outfit best known for solidly backing HD DVD during the two-year format war of the early 21st century -- was preparing to swallow its pride and kick out a Blu-ray player by the year's end, but now it's official. The outfit just announced moments ago that it has "applied for membership of the Blu-ray Disc Association (BDA) and plans to introduce products that support the Blu-ray format." Sadly, Tosh doesn't bother to mention exactly what kinds of BD-capable wares it hopes to produce, nor is it ready to disclose product launch time frames. We'd tell you exactly how it wants us to just be patient and all, but you're probably better off hearing it directly from the horse's trap:

"In light of recent growth in digital devices supporting the Blu-ray format, combined with market demand from consumers and retailers alike, Toshiba has decided to join the BDA. Toshiba aims to introduce digital products that support the Blu-ray format, including BD players and notebook PCs integrating BD drives, in the course of this year. Details of the products, including the timing of regional launches, are now under consideration. We will make announcements in due course."
