Q. im doing a huge research project so can anyone give me as much information on blu ray?
Answer
Blu-ray Disc (also known as Blu-ray or BD) is an optical disc storage medium designed by Sony to supersede the standard DVD format. Its main uses are high-definition video and data storage with 50GB per disc. The disc has the same physical dimensions as standard DVDs and CDs.
The name Blu-ray Disc derives from the blue laser used to read the disc. While a standard DVD uses a 650 nanometre red laser, Blu-ray uses a shorter wavelength, a 405 nm blue laser, and allows for almost six times more data storage than on a DVD.
During the format war over high-definition optical discs, Blu-ray competed with the HD DVD format. Toshiba, the main company supporting HD DVD, ceded in February 2008 and the format war ended[2].
Blu-ray Disc is developed by the Blu-ray Disc Association, a group representing makers of consumer electronics, computer hardware, and motion pictures. As of January 2009, more than 890 Blu-ray disc titles are available in Australia, 720 in Japan, 1,140 in the United Kingdom, and 1,500 in the United States.[3][4][5]

A blank rewritable Blu-ray Disc (BD-RE)
Commercial HDTV sets began to appear in the consumer market around 1998, but there was no commonly-accepted, inexpensive way to record or play HD content. In fact, there was no medium with the storage required to accommodate HD codecs, except JVC's Digital VHS and Sony's HDCAM.[6] Nevertheless, it was well known that using lasers with shorter wavelengths would enable optical storage with higher density. When Shuji Nakamura invented practical blue laser diodes, it was a sensation, although a lengthy patent lawsuit delayed commercial introduction.[7]
[edit] Origins
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 first DVR Blue prototypes were unveiled at the CEATEC exhibition in October 2000.[9] Because the Blu-ray Disc standard places the data recording layer close to the surface of the disc, early discs were susceptible to contamination and scratches and had to be enclosed in plastic cartridges for protection.[10] On February 19, 2002, the project was officially announced as Blu-ray,[11][12] and the Blu-ray Disc Founders was founded by the nine initial members.
The first consumer devices were in stores on April 10, 2003. This device was the Sony BDZ-S77; a BD-RE recorder that was made available only in Japan. The recommended price was US$3800;[13] however, there was no standard for pre-recorded video and no movies were released for this player. The Blu-ray Disc standard was still years away as a newer, more secure DRM system was needed before Hollywood studios would accept it, not wanting to repeat the failure of the Content Scramble System used on standard DVDs. On October 4, 2004, the Blu-ray Disc Founders was officially changed to the Blu-ray Disc Association (BDA) and 20th Century Fox joined the BDA's Board of Directors.[14]
[edit] Blu-ray Disc format finalized
The Blu-ray Disc physical specifications were finished in 2004.[15] In January 2005, TDK announced that they had developed a hard coating polymer for Blu-ray Discs.[16] The cartridges, no longer necessary, were scrapped. The BD-ROM specifications were finalized in early 2006.[17] AACS LA, a consortium founded in 2004,[18] had been developing the DRM platform that could be used to securely distribute movies to consumers. However, the final AACS standard was delayed,[19] and then delayed again when an important member of the Blu-ray Disc group voiced concerns.[20] 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.[21]

How Do I Hook Up A Blu-Ray Player?
Q. I have a 52" HD TV (1080p) and a JVC surround sound system that only plays regular DVDs. I want to buy a Blu-Ray player to put into this system. How do I hook it up? Please don't tell me I have to buy a new surround sound system to go with the new Blu-Ray player!
Answer
"Please don't tell me I have to buy a new surround sound system to go with the new Blu-Ray player!"
You already know the answer.
Does the 'system' have a extra optical or coaxial-digital input? If so, you just run either a toslink cable or video cable from the BlueRay player to this input and you have 5.1 surround sound.
If the 'system' has a Left/Right RCA audio inputs (colored red and white), you MIGHT be able to hook up RCA cables from the BlueRay player to these inputs.
But - standard DVD's include ProLogic sound track which work with the Left/Right audio outputs. I dont know if BluRay disks offer a ProLogic track. Check the menu system of the player to see if it will down-convert the sound to ProLogic.
