Whois & Analysis for dvdfab.cn

Blu-ray or Blu-ray Disc (BD) is a digital optical disc data storage format.

It was designed to supersede the DVD format, in that it is capable of storing high-definition (720p and 1080p) and ultra high-definition video resolution (2160p).

The plastic disc is 120 mm in diameter and 1.2 mm thick, the same size as DVDs and CDs.

Conventional (pre-BD-XL) Blu-ray Disc discs contain 25 GB per layer, with dual layer discs (50 GB) being the industry standard for feature-length video discs.

Triple-layer discs (100 GB) and quadruple layers (128 GB) are available for BD-XL re-writer drives.

The name "Blu-ray" refers to the blue laser (specifically, a violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs.

The main application of Blu-ray is as a medium for video material such as feature films and physical distribution of video games for the PlayStation 3, PlayStation 4, and Xbox One.

Besides the hardware specifications, Blu-ray is associated with a set of multimedia formats.

Ultra-high-definition television (also known as Ultra HD television, Ultra HD, UHDTV, UHD and Super Hi-Vision) today includes 4K UHD and 8K UHD, which are two digital video formats that were first proposed by NHK Science & Technology Research Laboratories and later defined and approved by the International Telecommunication Union (ITU).

DVD (an abbreviation of "digital versatile disc" or "digital video disc") is a digital optical disc storage format invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995.

The medium can store any kind of digital data and is widely used for software and other computer files as well as video programs watched using DVD players.

DVDs offer higher storage capacity than compact discs while having the same dimensions.

Multimedia is content that uses a combination of different content forms such as text, audio, images, animations, video and interactive content.

Multimedia contrasts with media that use only rudimentary computer displays such as text-only or traditional forms of printed or hand-produced material.

Computer software, or simply software, is that part of a computer system that consists of data or computer instructions, in contrast to the physical hardware from which the system is built.

In computer science and software engineering, computer software is all information processed by computer systems, programs and data.

Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media.

Computer hardware and software require each other and neither can be realistically used on its own.
