Amazon.com lists Chronos and Memento as Bluray titles for preorder. Should I add them to the list with a footnote? Willy Arnold 05:36, 17 June 2006 (UTC)
The contents are the same as the section listed in this article., should there be a link to that article instead of listing the whole again/merge the section intothe article? 202.71.240.18 08:05, 22 June 2006 (UTC)
Will Blu-ray discs be re-writable? The article doesn;t seem to mention this. thanks, Madd4 Max 19:39, 27 June 2006 (UTC)
I've removed the following from the article:
Besides having little to do with Blu-ray discs, as far as I can tell, since the HDMI 1.2 standard it has been possible to output SACD's DSD signal untampered via HDMI, which should be possible for the PlayStation 3 (which supports HDMI 1.3). A receiver can then decode the DSD signal. — Gabbe 23:19, 9 July 2006 (UTC)
How far off is this article? In fact, what is it that means it isn't a FA already? I just added a commons link, and it seems the article is damn close, a few more pictures and that should be it. Anyone agree? - Jack (talk) 14:13, 18 July 2006 (UTC)
I made a couple of minor updates to this Blu-ray page that point out the fact that every Blu-ray disc released so far has been on a 25GB single layer disc. This entire page compares Blu-ray to other formats, so I also mentioned that all HD-DVD movies released so far use dual-layer 30GB discs. I mentioned the fact that all Blu-ray movies released so far have chosen to use MPEG-2 compression technology used in standard DVDs. Similarly, I also pointed out that all HD-DVD discs currently use the much newer VC-1 compression technology. Sign: Mike_mgoblue
It's not a bad point to show how moronic studios can waste better technology. The blu ray discs have worse soundtrack and pictures because they are using 11 year old encoding. [1]. -- gatoatigrado 05:51, 7 September 2006 (UTC)
The fact remains that the majority of Blu-ray titles are 25 GB while almost all HD DVD movies are 30 GB. So I have added this back in the comparison section. Ray andrew 16:49, 12 February 2007 (UTC)
I don't really feel like going through the trouble of looking everything up, but I will say this. The first part of the article ends with "The Blu-ray Disc Association unveiled their plans for a May 23, 2006 release date at the Consumer Electronics Show (CES) in January 2006. Since then, Blu-ray was delayed, but finally shipped in the U.S. on June 20, 2006."
Just wanted to let the author know that the format was not shipped in the us on June 20, 2006, nor has it been shipped as of today, July 31, 2006. And it will, in fact, not be shipped until October 2006, according to Sony. I don't know the exact day, and I feel lazy. But you should certainly fix your error(s).—Preceding unsigned comment added by 128.172.143.174 ( talk • contribs)
Something this article does not answer and I'd like to see someone discuss is why virtually all Blu-Ray releases so far have been so-called "vanilla" releases. That is to say, releases with no (or virtually no) special features. And in some cases, the version released on BR is in fact inferior to that released on DVD. For example, when Ultraviolet was released, the DVD version was the extended directors cut, but BR only released the shorter theatrical version. Is there a particular reason for this? I definitely think it's a bad idea considering HD-DVD appears capable of including at least some special features (though that format also doesn't seem to have as many extras as the DVD releases). 23skidoo 15:46, 3 August 2006 (UTC)
Do you not think that the "Physical format" section should describe something abou the physical fornmat of the disc? Such as, say, its diameter? Daniel Barlow 09:58, 8 August 2006 (UTC)
The DRM section states: "The lack of a dynamic encryption model is what has made DeCSS a disaster from the industry's perspective: once CSS was cracked, all DVDs from then on were open to unauthorized decryption (commonly known as "ripping")."
Unless I am misstaken the word "rip" in the context of DVD:s specifically refers to *copying* the data off the disk. An extremely important point to make in regards to CSS and similar DRM is that they prevent unauthorized decryption *FOR ANY PURPOSE*, including *WATCHING* the content. I would like to update this paragraph to reflect the fact that CSS (and the proposed DRM for Blue-Ray) hinders playback on unauthorized devices (or with unauthorized software).
Opinions?
I happen to be involved with DRM and I can tell you that fellow engineers refer to it as Digital Restrictions Management. I don't know who decides what acronyms stand for but in the industry thats what we say. Maybe it wasn't intended to be called that but it is. I think I have a text book that sights it.
I have a question....
Is Blu-Ray disc capable of displaying 1080p resolution movies at 60 frames a second, or just 30 frames a second?
I know that digital broadcast and cable/satellite can only broadcast 1080p30, (which is only 12% better resolution than 720p60 :P ), because of bandwidth limitations of approximately 19Mbps. There is, however, no such limit on rate transfer on Blu-Ray disc; it might, however, be unable to store an entire 1080p60 feature-film on its 25GB of space.
Does anybody familiar with the specs know if 1080p60 is possible on Blu-Ray, and if-and-when we could see films released at that resolution on Blu-Ray disc? Pine 15:17, 21 August 2006 (UTC)
Wow, that really is eye opening! So, in essence, digital broadcast and cable/satellite usually only broadcast what an end-user would experience as 1080p24, and only occassionally what said EU would experience as 1080p30.
As for Blu-ray Disc's bitrate of 40Mbps, it is slightly more than double the bitrate of what ATSC defines as one "high definition" channel, (19.9 Mbps).
Does that mean that Blu-ray Disc has the ability to display 1080p60, (though not necessarily store a feature-length sample of it), or is there something else that I'm failing to take into account? Pine 14:29, 22 August 2006 (UTC)
I've made an infobox for media at {{ infobox media}}. I don't know enough about Blue-ray to apply it here. Dread Lord CyberSkull ✎☠ 14:35, 22 August 2006 (UTC)
i remember when blu ray was first shown it was easily scratched and was in a plastic case (like UMDs) should someone show that picture? i think its kinda interesting
Fox and Warner reported they will be releasing titles encoded with VC1, AVC and one in BD-50. http://bluray.highdefdigest.com/news/show/Disc_Announcements/Warner/Warner_to_Release_Record_Ten_High-Def_Titles_on_Sept_26/205 http://www.highdefdigest.com/pressrelease_foxbluraylaunch.html
What value does publishing all 170 companies have? The majority of them don't even have valid Wikilinks. It's just wasted space and is visually unpleasing. I vote to reduce the list to the board of directors. -- Navstar 20:53, 6 September 2006 (UTC)
Thanks Navstar! It looks nicer now. Good idea just putting in the companies that make up the board of directors. Snacky 02:49, 14 September 2006 (UTC)
Ok i may not know much about algorithms and stuff like that but what i do know is this thansk to Blu-ray next gen consoles like the PS3 will have larger games, better graphics and brillient frame rates even if Sony have had a few troubles with The PS3 not being able to read the discs, but knowing how long its been in production im sure it will have been conquered by now
I removed the comment "Sony has released a double sided disk which will end the hi-def war yadda yadda". This is not impartial nor are we remotely close to finding out which format will "win". —The preceding unsigned comment was added by 72.140.102.238 ( talk • contribs) .
WTF How are we supposed to traffic these blu-ray discs through warez? 50GB that is some bs lol :D Who will make the first .BD-R Release? nobody knows :D
I believe that there would be no 1.33:1 (full screen) Blu-ray discs of films originally represented in widescreen, because HDTVs are usually 1.78:1. There will probably be no open-matte Blu-ray versions of soft matte films. The Blu-ray releases of soft matte films will most likely be closed matte. The Blu-ray releases of Super 35 would probably be released as they were presented in widescreen. Decimus Tedius Regio Zanarukando 22:15, 1 October 2006 (UTC)
I think that Blu-ray burners could catch on if it was compatible with something usefull. Maybe if Norton Ghost was compatible - then people could really use these high capacity, rugged R/Rw disks and burners. For people in IT, this could cut costs of full system backups, and (inherent of compact disks) not break if dropped or temporarily exposed to moisture.

The two column arrangement in this section is nice, but some text is failing to wrap at the right end of the left column. Someone who understands markup here ought to take a look. Filing that, we should go back to a single column scheme. ww 05:34, 22 October 2006 (UTC)
should some of the compairisons between the two be mentioned? Shinigami Josh 03:58, 23 October 2006 (UTC)
why is sony making it seem like Blu-Ray is a new technology? Is it a market tactic to sell more players, because they fear that if people find out that blu-ray is really over 10 years old, they will see it at a failing technology for it now finally getting big?-- Indiearmy 05:30, 26 October 2006 (UTC)
Vandalism to this page is getting out of hand. Should we protect it?-- WW79 20:53, 7 November 2006 (UTC)
There doesn't seem to be any information on when Blu-ray will be released in Europe and the rest of the world, would be nice to know.-- Yuri Elite
Isn't the info on the Laser and optics ( http://en.wikipedia.org/wiki/Blu-ray#Laser_and_optics) already discussed in the overview? Basicly the same information making it somewhat redundant? I think that it should be either reviewed, expanded or just deleted maybe...
The information as seen in the overview:
A Blu-ray Disc can store substantially more data than the common DVD format, because of the shorter wavelength (405 nm) of the blue-violet laser (DVDs use a 650-nm-wavelength red laser and CDs use an infrared 780 nm laser), which allows more information to be stored digitally in the same amount of space.
The information as seen in the Laser and optics topic:
The Blu-ray Disc system uses a blue-violet laser operating at a wavelength of 405 nm, similar to the one used for HD DVD, to read and write data. Conventional DVDs and CDs use red and infrared lasers at 650 nm and 780 nm respectively.
P.S. If the title seemed misleading, I was just trying to be funny... sorry.
I haven't been able to find a good summary of the spec, but somewhere out there is a specification of what a Blu-ray disc is, because the engineers designing a player must know exactly what it is supposed to be able to read. Can someone verify that quad-layer discs are part of that spec? If not, then the mention of such discs should be removed from the article, because they're not Blu-ray discs. These phrases like "up to 200 GB" are meaningless. Even a CD-ROM could have 200 GB capacity, if you allow its structure to deviate from the CD spec. Spiel496 19:13, 24 November 2006 (UTC)
The article says 3.01 million blu ray discs sold. This can't be true as Motorstorm and Resistance together have sold more than that and well over 20m bluray discs have been sold. If they are not included the sentence should be edited appropriately such as "3.01 million videos have been sold on bluray format and 20m games". I think it'd be pertinent to mention ps3 games after this as bluray being the only represented HD disc in the current generation of consoles is quite an important factor.
For me this sounds rather redicolous. As far as I know blue semiconductor lasers have a life cycle around 1000 hours. In case you are very lucky. BD and HDDVD players utilises light source known as laser diode. It allows to increase lifetime of source greatly - up to 15000 hours. If anyone seen yellow mark with "Class I laser product" on your BD/HD DVD player please report. I have no such things on PS3 Vadim Mayorov 14:14, 9 June 2007 (UTC)
I believe the maximum bitrate for Dolby Digital Plus audio on Blu-ray is 4,7mbits instead of 1,7. Blu-ray specs allow for a 640kbits Dolby Digital packet plus up to 4 packets of 1 mbit DD+ audio.
No, the current spec only allows for one extension packet for a total of 1.7mbit/s see the references on the Dolby digital plus page for details. -- Ray andrew 22:04, 8 May 2007 (UTC)
