Where have you ben hidding for the past 2 years..lol

Answer 2

It's the next generation in home entertainment. Blu Ray offers lossless sound quality and pristine 1080p HD picture ( regular dvd has only 480p). The blu ray disc does not wok on a regular dvd player, they only work on a blu ray player or the ps3. If you have an HDTV that supports 1080p/i be prepared to be amazed, the movie looks and sounds so good compared to the dvds, you'll switch to buying blu rays only!

Answer 3

as you know Sony and tobisha had a war of formatting for the next generation, Sony had the blue ray and Tobishaw had the HD DVD(http://ps3media.ign.com/ps3/image/articl...

Sony won the war:

" Blu-ray Disc



Blu-ray, also known as Blu-ray Disc (BD), is the name of a next-generation optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of the world's leading consumer electronics, personal computer and media manufacturers (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson). The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc. This extra capacity combined with the use of advanced video and audio codecs will offer consumers an unprecedented HD experience.

While current optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-RAM rely on a red laser to read and write data, the new format uses a blue-violet laser instead, hence the name Blu-ray. Despite the different type of lasers used, Blu-ray products can easily be made backwards compatible with CDs and DVDs through the use of a BD/DVD/CD compatible optical pickup unit. The benefit of using a blue-violet laser (405nm) is that it has a shorter wavelength than a red laser (650nm), which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it's possible to fit more data on the disc even though it's the same size as a CD/DVD. This together with the change of numerical aperture to 0.85 is what enables Blu-ray Discs to hold 25GB/50GB.

Blu-ray is currently supported by more than 180 of the world's leading consumer electronics, personal computer, recording media, video game and music companies. The format also has broad support from the major movie studios as a successor to today's DVD format. In fact, seven of the eight major movie studios (Disney, Fox, Warner, Paramount, Sony, Lionsgate and MGM) have released movies in the Blu-ray format and six of them (Disney, Fox, Sony, Warner, Lionsgate and MGM) are releasing their movies exclusively in the Blu-ray format. Many studios have also announced that they will begin releasing new feature films on Blu-ray Disc day-and-date with DVD, as well as a continuous slate of catalog titles every month.

and blu-ray also can be used for gaming and the Ps3 is the CURRENT system with blu-ray gaming

These are rather confusing times in the world of home theater and even next-generation gaming. With the move to new high-definition optical disc formats in the way of HD-DVD and Blu-ray, hardware makers and studios are utilizing some rather stringent anti-p****y means in order to prevent movies from being copied, especially in HD. The side effect is that these means will prevent some users from being able to take full advantage of the formats, and the details behind all of this is causing quite a bit of confusion.

Both HD-DVD and Blu-ray employ an AACS (Advanced Access Content System) copy protection scheme that, to keep things short and (somewhat) simple, will down-scale HD content to a non-HD resolution if it isn't displayed over an HDCP-compliant HDMI connection. In other words, hooking up either of these formats via component connections won't cut it for true HD playback, at least in the future. Luckily, studios behind both formats have said that they won't ship their first batches of movies (possibly for a few years) with the scheme enabled to give users time to shift over to HDMI-enabled televisions, but this still leaves many questions in the world of gaming, specifically with regards to the PlayStation 3.

The main concern is whether or not gamers will be able to play PlayStation 3 titles in high-definition if they're "only" using component cables. Luckily, Blu-ray's copy protection scheme should have no impact on gaming whatsoever and PS3 gamers will be able to enjoy their next-gen systems at HD resolutions with any sort of HD-capable connection. This means HDMI, VGA, DVI and component connections would all work in HD, assuming these connections are all supported by the PS3's "Multi AV-out" port. Composite and S-Video would only work in 480i, of course.

The technical reason for this is that Blu-ray's AACS system is both hardware and software based, and any protected software will need to contain an Image Constraint Token (ICT) to essentially turn on the protection scheme. In other words, this is optional and whoever authors the media has the option of utilizing the AACS scheme or not. It's very much like how some VHS tapes have Macrovision and some don't.

You won't need these for HD gaming.In practice, it wouldn't make any sense to copy-protect the image output of a videogame. With movies, this makes obvious sense as the movie is wholly visual - that's its purpose and only existence (well, plus audio, of course). With gaming, the visuals only work to parlay the experience of interaction, which is what publishers are selling. If people stopped buying games and just started downloading 12-hour video walkthroughs, this might be a problem, but we don't foresee that happening, well, ever. It's possible that a company like Square may want to apply something of this sort to its cutscenes at some point in the future, being as so much money and production time goes into the making of these cinematics, but even this is rather unlikely.

There are rumors and rumblings that some older sets, HD or no, will simply not work with the system at all. This is not true whatsoever. It's true that you may not be able to play some future Blu-ray videos in HD resolutions on these sets, but they'll be perfectly fine for gaming. A good, basic rule of thumb is that if you can display HD video from any other component in your home theater, be it your cable box, Xbox 360 or whatever else, then it'll work fine with PlayStation 3 games. And even if you have some 1976 set that barely works, you can be sure there will be some way to get a PlayStation 3 connected to the POS.

With all of this confusion, some folks may wonder why Sony has been so outright steadfast about including Blu-ray in the PlayStation 3. Aside from simply making things confusing, the format has also played a large role in the system's delay to November of this year.

Really, there are multiple answers to this. First and most obviously, gaming benefits most from Blu-ray's massive storage capabilities, with dual-layer discs capable of holding up to 50GB of data. Dual-layer HD-DVDs can store about 30GB by comparison while dual-layer DVDs can store around 9GBs. The Blu-ray Disc Association is currently experimenting with eight-layer discs capable of holding a whopping 200GB of data. If that's not enough room for you RPG gamers out there, we don't know what is.

More importantly in Sony's long-term plans as an electronics giant, however, is Blu-ray's role in movies. While Blu-ray will likely do fairly well on its own (once the prices come down to more consumer-friendly levels, anyway), Sony is using the PlayStation 3 to act as something of a Trojan Horse to get players into people's homes. If the PS3 is roughly as successful as Sony's past consoles, that would mean somewhere around 100 million Blu-ray players in homes all over the world in around five years or so, not counting standalone players.

Being as Sony pioneered the technology, should Blu-ray win out over HD-DVD and supplant DVD as the standard in home video, the company stands to make a fortune raking in a small percentage for every Blu-ray disc sold, similar to how it currently takes a licensing cut for every PlayStation game sold.

Now, one other question that people have is whether or not the PlayStation 3, and all other Blu-ray players for that matter, will be able to play their current DVDs and CDs. Yes, it will. In fact, just about the only media type that the PlayStation 3's Blu-ray drive won't be able to read is HD-DVD. There's no word yet from Sony on whether the system will up-scale DVDs to HD resolutions, though we'd be a bit surprised if it didn't. Although, the Xbox 360 doesn't so...

That should wrap up most of the pending questions that people seem to have about the PlayStation 3's Blu-ray capabilities and any adverse connectivity effects its copy-protection scheme may bring with it. Hopefully Sony will announce the last few tiny details at its press conference at this year's E3, like the exact drive speed, DVD up-scaling and so forth. But regardless, rest assured that you won't have any problems playing games in high-definition on your current display.

Answer 4

blu ray is like a the new jordans nothing

Answer 5

Blu-ray gives you a ten time better picture than normal dvd

Answer 6

Blu-ray is a disc with a 50+ Gig capacity. HD dvds or only good for 25 gigs. whitch means more detail

Answer 7

It's the next generation format of entertainment on discs. They hold about 9x more data than ordinary DVDs. Single-layered Blu-Ray discs are 25GB, while Dual-layered are 50GB. If you hooked up a PS3 to an HDTV via HDMI cable and played a Blu-Ray movie on it, you will be amazed at the picture and sound quality. All PS3 games are in Blu-Ray format. Sony made it this way so game developers can make games that are bigger, longer, more massive, and have the best graphics around.

Answer 8

Blu-Ray is a disc format that movies and now playstation 3 games are played on. The blu-ray format gives developers 8 times the space of traditional disc formats (such as those on the wii and 360) to create unbelievable graphics, intelligent AI, huge game worlds, and extremely detailed and polished games not even possible on other systems.

Answer 9

Basically blu-ray (yea, there's no "e" because they can't put a copyright on the word "blue") is a format of disc. it's like a DVD, except much better. DVD's store 5gb of space, to fit the movie. But blu-ray fits 50gb of space, allowing it for much more. they use this to put in extra detail making all blu-ray movies in 1080p hd (high definition). 1080p is currenty the best hd out there, it's the most detailed and best quality. and for the ps3, all ps3 games are on blu-ray discs. however, not all of them are 1080p, although they can. and with 50gb of space, ps3 games can be huge. and since ps3 games are blu-ray discs, all ps3's can play blu-ray movies.

however, if you don't have an hdtv, then blu-ray won't be useful for you
