Question

Difference between dvd and blu ray.....?

Answer 1

Capacity. I think Blu ray will win over HD-DVD because of the playstation 3. DVDs can store 9.6GB of data, and blu ray can store a whole lot more, suitable for High definition films

Answer 2

defference in tech and storage

Answer 3

DVD=480i Lines of resolution) or 480p with deinterlacing

HD DVD and Blu-Ray = 1080p

Incedentally Blu-Ray just won the HD format war!

Answer 4

There's regular DVD, High Def-DVD, and a competitor's high def DVD called Blu-Ray.

Obviously both high def DVD (HD-DVD) and Blu Ray do the same thing - a true high def picture and sound quality that is superior to traditional DVD.

The one thing we know from history, is like the Sony Beta-Max VHS format of the early 80's, or even the DIVX format from a few years ago; one of these formats will not be around for long.  People will start to favor one over the other, and the other will go out of production.

That's why I am waiting to see which one comes out on top before I buy (plus the prices will be cheaper then anyway).

Answer 5

Blu ray is in High definition, dvd has no hd unless it says so on the box

Answer 8

Blu ray has a more clearer picture and quality then a DVD player. Different technology and laser.

-Blu-ray Disc is a high-density optical disc format for the storage of digital information, including high-definition video.Like its rival format HD DVD, Blu-ray uses a "blue" (technically violet) laser operating at a wavelength of 405.The blue-violet laser's shorter wavelength makes it possible to store more information on a 12 cm CD/DVD sized disc. The minimum "spot size" on which a laser can be focused is limited by diffraction, and depends on the wavelength of the light and the numerical aperture of the lens used to focus it. By decreasing the wavelength, increasing the numerical aperture from 0.60 to 0.85 and making the cover layer thinner to avoid unwanted optical effects, the laser beam can be focused to a smaller spot. This allows more information to be stored in the same area. In addition to the optical improvements, Blu-ray Discs feature improvements in data encoding that further increase the capacity

-DVD  is a popular optical disc storage media format. Its main uses are video and data storage. Most DVDs are of the same dimensions as compact discs (Cd's) but store more than 6 times as much data.

DVD/Video and DVD-Audio discs respectively refer to properly formatted and structured video and audio content. Other types of DVD discs, including those with video content, may be referred to as DVD-Data discs. The term "DVD" is commonly misused to refer to high density optical disc formats in general, such as Blu-ray and HD DVD.DVD uses 650 nm wavelength laser diode light as opposed to 780.
