Get Information That You Should Know About Blu-Ray And HD DVD

Movies are finally ready to take advantage of high definition displays in the stores for years. DVD's brought us great picture and sound that a tree in the television and home theater market created. Display technology rapidly grew to an image that us two times as well as DVD-quality video. The problem was that DVDs can not store enough information to HD-quality video and sound, suitable to date. New technology has a DVD that can store up to five times more information than before. This new technology comes in two sizes called Blu-Ray and HD DVD. These two formats were created separately and they currently compete with each other. They both use similar technology to HD-quality video and audio, but they do have a number differences.The technology behind the two formats is based on the same optical technique that regular DVDs use. A laser is directed at the surface of the disc and reads the digital information is converted to video and audio. Blu-Ray and HD DVD incorporate a new colored laser that can be more focused on a smaller area of the disk. This may there be more information packed on the same size disc. It is like a turntable with a smaller needle and lines are tighter together just moved to the center, allowing more space to the exterior for more information. The reason for the fact that the data fit the same size as a DVD disc so that all optical discs created with older technologies will fit into the same reader. So a Blu-Ray or HD DVD player plays CD, DVD and their own discs. Because of their competition are no players that will play Blu-Ray and HD DVD.The main difference between the two formats is simply a matter of storage. HD-DVD can store 15GB and about three times as much as a DVD. A Blu-ray disc can store 25GB which is about five times as much as a DVD. Both have the same video resolution as of now, but Blu-Ray has the potential to improve the video store when available. For now, extra space is used for film extras like behind the scenes segments. Only time will tell whether these formats will merge or fight it out until the end. History has taught us that a format usually prevails.

HD-DVD offers the same technology, although it is unable to hold as much information as Blu-ray. Developed by Toshiba and NEC, it is able to take three times as much data as traditional DVDs. While this may be less than Blu-ray, the data capacity of HD-DVD is still higher than the amount needed for major blockbusters in high definition viewing. HD-DVD also came much earlier and was first cited as the successor of the standard DVD format. HD-DVD is fully compatible with HD-DVD players, which in turn are compatible with HD televisions. High-definition technology is definitely the wave of the future of home entertainment and HD-DVD formatted disc is the first technology. Both Blu-ray and HD-DVD use a new type of laser which improves as the standard DVD uses. While older, standard DVD models use a red laser to transfer the content from disc to play to the screen, these two technologies use a blue-violet laser instead.

However, with the added experience in the production of more and more consumers are familiar with the name, it is very possible for them to pull ahead. The race to the top home-entertainment format will continue on and consumers will just have to wait to see which wins. In the meantime, players are available for both formats and some manufacturers have players that meet both formats. ~ Ben Anton, 2007
