|  I have seen a lot of ads showing some kind of new super powerful magic High Definition DVD player, what's the deal with this, how is that possible, does it mean that will have to buy another DVD player soon? What will happen to the plain old discs? 
Lisa Myers Ooops! I did it again! |

| | Actually the High Definition DVDs is just one side of the story; as of mid 2006 there are 2 technologies covering pretty much the same technology, high quality video to take advantage of the new High Definition TV screens, here we explain a little bit about both techologies, HD DVD and Blue Ray DVD: Regula DVDs can hold 4.7GB of information, but many want a higher-capacity successor to accommodate the larger data demands of high-definition video. HD DVD and Blu-ray both use blue lasers to read and write data; because blue has a shorter wavelength than the red used in DVD and CD lasers, information can be packed more densely on a disc and a single disc can hold more. Both HD DVD and Blu-ray drives are able to read current-generation DVDs. It's no surprise why manufacturers want part of the industry. DVD player shipments, including next-generation models, will diminish from 113 million this year to 78 million in 2009, offset by a DVD recorder increase from 17 million this year to 74 million in 2009. What are the differences between Blu-ray and HD DVD?
Each next-generation DVD format comes in single-layer and dual-layer formats. For HD DVD, that means capacities of 15GB and 30GB; for Blu-ray, it's 25GB and 50GB. Toshiba earlier expected HD DVD during 2006 but now the company plans to launch products worldwide in the first quarter of 2006. That's about the same time as the spring launch of Blu-ray, eliminating the early debut advantage. Blu-ray uses Sun Microsystems' Java software for built-in interactive features, whereas HD DVD uses a technology called iHD that Microsoft and Toshiba have worked on. For now, just hold on to your plain old and very entertaining DVD player, wait a couple of years to have a real library of movies and to the world to decide which technology will prevail. Keep watching! |
