A New Form of Digital Media - Blu-Ray
Technologies have come a long way of the past a number of has altered the technique in which people vie their movies. It is possible to probably remember the days when individuals watched their property movies through their VCR's. Naturally these VHS tapes were bulky, consumer a great deal of storage room, and output much lower quality visuals than seen today with DVD's and also the emerging BD media. LaserDiscs's soon thereafter replaced the VHS and VCD's however, this was short-lived when DVD was introduced to the scene. DVD (Digital Versatile Disc) was of course a lot more advanced than VCD and stored six times more info.
A single DVD with a storage capacity of 4.7 GB can do storing one full-length movie and also other behind-the-scene footages as well as other extra features. For that reason, DVD's experienced a serious effect on the video industry and for that reason a greater number of folks are purchasing DVD's to see of their homes. The DVD may however get replaced by a new technology that will further improve the movie industry. The new Hi-def media technologies are called Blu-ray.
Obviously BD's are consider by many to be the next gen format to adopt off when DVD's set out to drop. Blu-Ray Discs or BD can record, store and can play more video, digital audio, in addition to data. BDs may also store a full length high-definition movie which often requires a higher bandwidth and storage space. When compared with DVDs. Blu-Ray Discs have the advantage on the amount of information that it can store. A single-layer BD has the ability to store 27 GB of digital information. A blu-ray disc has such a large capacity in comparison with DVD because the nation's capability to hold up to 13 hours a greater portion of standard video. A double-layer BD conversely might be capable to store more than 4.5 hours of high-definition video for the 50 GB storage capacity.
Laser lights are effectively the best way optical disc storage media (for instance DVD and Blu-ray) can read information, with Blu-ray utilizing blue violet rays whereas DVD uses red ultraviolet rays. How much information that can be stored in discs is dependent on the size of and precise the laser light is. Blue laser includes a shorter wavelength in contrast to red laser websites as bad this, blue laser is more precise and can write information in smaller sized spaces. This is why a lot more information can be kept in a Blu-Ray disc.
A huge storage capacity is not only good thing about a Blu-Ray technology. Blu-Ray Discs also can transfer information in a higher rate. Blu-ray discs are really revolutionary because they are competent at a knowledge transfer rate of 36 Mbps (megabits per second) whereas an ordinary DVD are only able to transfer at a rate of 10 Mbps.
Two technologies namely, Blu-ray and Definition DVD (HD-DVD)are competing with each other to actually become the official storage medium in the future of high definition media. Blu-Ray discs were first used by Sony of their PlayStation 3 games websites as bad this, BD has become becoming popular among giant movie production studios for example Warner Brothers who have claimed that they will only release their High-definition movies in BD formats starting May of 2008.
