what's blue ray?

Answer 1

To make this very simple for every body to understand without going into a long drawn out 3 paragraph report:

When you go into your local Blockbuster you will see Blu-Ray and HD-DVD. Neither one of these will play in an ordinary DVD player. You either have to have a HD-DVD player or a BLU-Ray DVD player. Both of these play the exact same quality of HI-DEF signal. The only difference between the two is that BLU-Ray technology allows you to bring up interactive menus. As it stands one of these technologies will be going away. The Studios like the Blu-Ray Technology but HD-DVD players are cheaper than the Blu-Ray players and the HD-DVD movies are moving alot better in stores in rentals and sales. More than likely from friends I have talked to at Disney is that they believe HD-DVD will be the standard and Blu-ray will go away. I don't know if you some of you are old enough to remember back in the 1970's there was Beta-max and VHS. The studios liked the Beta -Max over VHS because it was better picture quality. In the long run VHS won over Beta because it was cheaper!!. The same thing will happen here. HD-DVD will prevail over BLU-Ray for the very same reason. There will be no room for both Technologies. Consumers are to fickle

Answer 2

It is the newest DVD format out, but it can only be played on a Blue Ray DVD player, or the Play Station 3.

Answer 3

Blu-ray is a format for high definition movies. The picture quality is a higher resolution than DVD so the quality is much better. Blue Tooth is for devices like headsets, mice or wireless keyboards. The signal is wireless so it doesnt need to be aimed directly like an infra red signal. It doesn't need line of sight.

blue ray is a different type of dvd format.

**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) are supporting the Blu-ray format and five of them (Disney, Fox, Sony, 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.
