From what i understand, blu ray disc was backed by a group of investors which included Sony. Why is it that Sony gets all the credit? Standard dvd was never referred in that way.

Well it wasn't only them that invented it, but they were the company that poured the most investment into its production.

Get your facts straight. Sony and many other groups created Blu-Ray.

Sony simply because has the biggest credit is because they are the biggest share holder under the Blu-Ray name.

I beg to differ, and at least have the proof to back it up. Initial source - Wikipedia Sony initially started with two projects for being able to make optical media that could store high definition content: UDO (which kinda orphaned out), and DVR Blue. DVR Blue was first shown off @ CEATEC in 2000, where Toshiba was showing off AOD (which led the way to HD-DVD ). Later, they decided to call it BluRay so that they could patent the name along with all their intellectual property in the format. The DVD Forum did not accept BluRay at the time because of those stupid ridiculous cartridge caddies they initially decided to keep them in; HD-DVD on the other hand was a logical evolution to DVD, as much of the same tech that already went to making DVD media could be reused and simply tweaked to make HD-DVD discs and drives. Thus, HD-DVD was ratified by the DVD Forum as their preferred replacement, where BluRay took too late to find a way to ditch the caddy cartridge.

If you're going to cite a source, you could at least quote it or represent it correctly.

"Blu-ray was developed by the Blu-ray Disc Association, a group of companies representing consumer electronics, computer hardware, and motion picture production. The standard is covered by several patents belonging to different companies. As of March 2007, a joint licensing agreement for all the relevant patents had not yet been finalized"

"Sony started two projects applying the new diodes: UDO (Ultra Density Optical) and DVR Blue (together with Pioneer), a format of rewritable discs which would eventually become Blu-ray Disc (more specifically, BD-RE).[8] The core technologies of the formats are essentially similar."

"The Blu-ray Disc physical specifications were finished in 2004.[32] In January 2005, TDK announced that they had developed a hard coating polymer for Blu-ray Discs.[33] The cartridges, no longer necessary, were scrapped. The BD-ROM specifications were finalized in early 2006.[34] AACS LA, a consortium founded in 2004,[35] had been developing the DRM platform that could be used to securely distribute movies to consumers. However, the final AACS standard was delayed,[36] and then delayed again when an important member of the Blu-ray Disc group voiced concerns.[37] At the request of the initial hardware manufacturers, including Toshiba, Pioneer and Samsung, an interim standard was published which did not include some features, like managed copy."

Additionally, Blu-Ray was never submitted to the DVD Forum to succeed DVD and even against no formal competition HD DVD didn't fair too well either.

"In August, Toshiba and NEC announced their competing standard Advanced Optical Disc.[16] It was finally adopted by the DVD Forum and renamed HD DVD the next year,[17] after being voted down twice by Blu-ray Disc Association members, prompting the U.S. Department of Justice to make preliminary investigations into the situation.[18][19] Three new members had to be invited and the voting rules changed before the vote finally passed."

Actually HD-DVD was accepted because Toshiba chose to change the rules and ignore all the abstentions from Sony, Samsung and many, MANY other companies. HD-DVD was a last minute bit of desperation by Toshiba to try and retain all the royalties they were getting on DVD.

I for one am glad they fell on their butts, we wouldn't even have had to deal with the format war if not for Toshiba.

At least Toshiba products work. Now we have to deal with finding nightly firmware builds to let our movies work (as evidenced with every new Fox BluRay to have come out since Fantastic4), and buying a new player every single time that Sony decides to change up the spec (BD-Live {2.0}won't work on any stand-alone out right now, and there's already work on a v2.1 spec for BluRay), and in my case, go through about five or six bluray players before finding one that won't chew up my damn library like every other Sony disc drive has done for me. :cry: :evil:

Thats a funny comment considering the HD DVD standard and player standard was A LOT more fleshed out from the beginning, there are still things about the Blu-ray standards that are all over the map and work differently based on which player you own.

And which will end up superior? Toshiba ignored the need for a HD-capable disc for a long while and now they are paying for it. The BDA has already essentially said that Toshiba forced them to launch earlier than intended, so you can thank them for the incomplete spec also.

Incomplete how? The only real knock on the HD DVD was the lack of space.

Studios didnt like the region free, but that wasnt because it wasnt complete, consumers like this fact.

I suppose you also like the Bluray disc forcing you to watch commercials and previews. Instead of being able to hit the menu button, you have to next through them. Good thing about the extra space they can have 10 - 15 of these instead of 3 or 4.

I'm trying to find it now but having a hard time. Also, I think I mis-wrote it. I meant to say that there is already a BD 2.0 to come out, and there were talks about a BD 2.1 specification. Sorry for the misunderstanding. :oops: And given how many of the BluRay supporters/fanboys were talking about how the media can have up to 8 layers of data in the single physical disc, you'd have to be foolish to not expect that one or two of these major shifts will require a new BD profile that the Sony PS3 cannot just simply upgrade to by software. There are still commercial DVD players made now that won't read a DVD+/-R DL disc of any sort. Sony will undoubtedly pull every software voodoo trick in the book to ensure their PS3 can play BluRay movies, to the point that stand-alone players are useless to purchase now, unless you go for one of those dual-format players that can also play HD-DVD movies still. Honestly, I'd have rather just "dealt" with the reduced storage capacity of HD-DVD than to deal with the inevitable revision whimsy fetish that Sony will exercise in full force with BluRay.

Anyone who buys a player now fits solidly into the early adopter camp and so I'm not particularly concerned about them. If I had half the money to buy one of the players from either camp I would have been a lot better off now.

I wish I could afford to go with either. But the simple fact is that more of the movies I cared about watching in high definition were released on HD-DVD. 300 was on both, but the HD-DVD copy was many times better than the BluRay copy due to all the additional audio codecs supported, additional languages (I have family that speak/read different languages, and sometimes multilanguage comes in handy to learn a new language :)), and even had a full-on game on the disc. Matrix Trilogy and Transformers are still only on HD-DVD. And at least the HD-DVD camp was a bit more honest about what you were getting over BluRay @ launch. When both first debuted, it was Toshiba's HD-A1 and Samsung BDP-1000. As many A/V-phile sites found, the HD-A1 read the media internally @ 1080p, but didn't have the video hardware to push beyond 1080i. On the other hand, the BDP-1000 read movies internally @ 1080i, but deinterlaced to make 1080p. Combine with the fact that most movies in HD-DVD started @ VC-1 where most initial BluRay were MPEG2 (basically same as DVD), and HD-DVD was getting the picture quality crown quite a bit. The Xbox 360 HD-DVD add-on drive was also a really good player, whose only real limitation was that if you'd a 360 that doesn't have an HDMI output or used it, then HD-DVD movies output in 1080i over component, but were 1080p on VGA. And when it came down to the movies, the HD-DVD extras were (IMO) much better thought through and much better fleshed out than the same movie's on BluRay, or the equivalent BluRay. It's hard to deny how cool it is to be able to see a as-it-happens readout of health on each of the decepticons/autobots in Transformers (HD-DVD) compared to having a Space Invaders-rip off like in Chicken Little (BluRay). If I could, I would try to buy that LG dual-format player right now, so that I can at least be able to have the best of both worlds. It would beat having to go through five or six PS3's. :evil:

Maybe, but all any of the movie studios seem content to do with BD-Java is to use it for additional DRM, like Fox. :|

BD-Java is not BD+ and Fox is about the only studio that has at all adopted that so far (at least that I'm aware of) look at the upcoming titles list, theres already quite a few movies with BD-J and they will only improve down the line.

Interesting choice of word, "will".

Like I said in earlier post, the Blu-ray format is all over the place. Maybe now they can settle in and get the format standardized across players and software designed to work with the format. Its more than a mess at this point.

Please Sony can you get rid of all of the ads on your disc? I am paying enough of a premium that I shouldnt have to be subjected to them.

Would be possible if we could actually burn our own backups with reasonable chance of them working. But the **AA's and Sony wouldn't let such a thing happen, oh no! For a BluRay disc to work, it needs to have AACS, BD-ROM Mark and BD+, or else it won't play. Source Comparatively, all a burned HD-DVD format disc needed was AACS.

That says pre-recorded disc, which means that it wouldn't be something you would use to record on yourself. Explain to me again how the Blu-Ray burners out there work if they all require that protection?

Copy protection is always broken and with Blu-Ray the risk of it being damaged is so reduced that its not a real concern for me. There are disadvantages which will be overcome, the baseline advantages are what convinced me it was the better way to go.

Don't think for a second that Toshiba wouldn't have introduced region codes (there was already some discussion of such a move) and do you seriously think they wouldn't have added additional copy protection when AACS was cracked? I doubt it, its the endless digital arms race and the internet has a good record so far.

What? now you are grasping at straws. The players didnt support it, so now they are going to add it and make the early players obsolete. Whatever, its moot point now. Its just funny that "consumers" supported the format that was better for the studios... Not.

Once again the consumer was screwed by the Studios and we continue to let it happen. We ended up with the product that allows them the most control in our household.

For quite a while, now, Blu-Ray titles have been outselling HD DVD by 2:1 or more. Are you saying the studios are buying these disks from retail to artificially inflate their numbers or are you projecting your wishes upon the general populous?

Actually its true HD-DVD Forum working on region codes.

But they never did finalize them because they were too concerned about losing (which they now have) and Blu-Ray has three regions instead of six, I still consider than an improvement.

Blu-Ray is very much a mixed bag, but aside from tighter copy protection it's mostly a big improvement over DVD.

Combine with the fact that most movies in HD-DVD started @ VC-1 where most initial BluRay were MPEG2 (basically same as DVD)codezer0

That's not entirely accurate. MPEG-2 can look as good or better than VC-1 (and even AVC/h.264) if given enough bitrate. In fact, many HDV cameras actually capture in MPEG-2 and that raw footage is later compressed with AVC or VC-1. The big problem with early BD releases using MPEG-2 was that the single layer discs at 25GB didn't provide enough room to give the MPEG-2 media the proper bitrate it required.

In all honesty who cares, the point was the initial stuff encoded in MPEG2 didnt look very good, you are splitting hairs.

Although there were also HD DVD's that didnt look so hot either, Goodfellas, Oceans 13 are two examples. Both formats were putting anything and everything on their "HD" disc.

And what kind of read speeds would you need to make 1080p MPEG2 at a high enough bit rate to actually look as good as you claim? And how much shorter would the movie times have to be to justify? It's kinda like saying "Oh sure, we can have 1080p on a standard CD-R! but you'll only have about five minutes worth of video and a drive that can read it @ 56X!" Clearly, not practical.

Here are two examples of MPEG-2 done correctly: Kingdom of Heaven, and Tears of the Sun. From a purely visual standpoint, an MPEG-2 transfer can be just as impressive as the newer codecs. Just because MPEG-2 requires a higher bit rate than AVC and VC-1 does not make it inferior. It does make it less efficient, which makes it harder to include lossless audio and supplemental material while delivering a top notch image.

Blu-ray launched a good 6 months early because of HD-DVD. They were in a mad scramble to get movies on the shelf and it showed in the image quality of those first releases. MPEG-2 was used in the beginning because it was familiar. Period. They could deliver an HD transfer quickly. At the very least they weren't familiar with the newer codecs, and quite possibly were not even equiped to author discs with them.
