What's Behind the Technology of 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 some 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. 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. More great information about Blu-Ray and other emerging technologies is available at http://www.find-hddvd-blu-ray-information.info

Toshiba Has HD-DVD-R Ready for Mass Production

The time has come for Toshiba and NEC, the main backers of HD-DVD format to announce that they are ready for single HD-DVD-R disc mass.

Similar blue-laser technology remains the core of both formats, such as blue laser has a shorter wavelength than the red lasers used in current DVD equipment, allowing discs to store data at higher densities needed for high-definition TV and films. The advantage of the HD-DVD-R disc has more than its main competitor, the Blu-ray Disc is the same disc structure as conventional DVD and therefore can be manufactured using the same production. This, for the DVD manufacturers, they can start with HD DVD-R mass production at full speed, immediately, with little extra cost. A replacement stamper is obviously needed and the old paint should be replaced with blue-light sensitive dye resin. The new dye was developed in a joint project by Hayashibara Biochemical Laboratories, Mitsubishi Kagaku Media / Verbatim and Toshiba Corporation. But at the same time, Blu-ray competitor has its own advantages, including higher storage capacities. Toshiba claims that work on this aspect also, but the transition from single-layer discs are written at 1x speed, dual-layer 30GB discs can take several years, her spokesman said. Promised 20GB Toshiba HD-DVD-RW discs entering this time next year. So far, the Blu-ray Disc Association HD DVD Promotion Group and refused to compromise to a single hybrid model for the future DVD.

In Frye's in the weekend I saw two half shelves worth of HD-DVD software. This is remarkable because I had not been to an electronics store recently for some screen. I know they are out for weeks or one months or I do not care. The HD-DVD were grouped at the end of the anime section just for the nature and historical videos. I can not remember the first weeks or months of the launch DVDs, but it was probably just as pathetic (I just remember seeing Eraser and Twister DVDs for one years before I cared about DVD as a source of entertainment). The discs are packed in clam same cases as normal DVDs, the HD-DVD "banner at the top was the only tip-off. Blockbuster! / Must buy!

What Is HD Dvd?

HD DVD stands for High Definition Digital Versatile Disc. It is a thin circular disk and looks almost exactly like a CD or DVD. It is actually very similar to CDs and DVDs in all aspects except one. The difference is that HD-DVD a lot more information than the CD can hold / DVDs from the past. The way they packed more information in the same room does come from the color of the laser used to read the disc. HD-DVDs are read by a blue-violet laser instead of the traditional red bar. The blue-purple color has a shorter wavelength, making it able to focus on a smaller area more precisely. That way you can just stuff all of the information closer together on the same size disc. How much more? An HD-DVD contains about 3 times more information than a DVD. This extra space can fit HD-quality movies and sound. In particular, a 720p/1080i resolution 480i vs a picture on a DVD movie. A disk can contain any other type of information in addition to movies, but video is the most popular use for a DVD world. This is why many companies compete for HD home theater DVD players release. Paramount Pictures, Warner Bros. and Universal Studios have been lists of titles that will be available on HD DVD. Toshiba has already announced that it will produce two players. HD DVD is in direct competition with Blu-Ray, a similar technology that is not compatible implements. Blu-ray developed by Sony and is supported by the Blu-Ray Association including Apple, Hitachi, Dell, HP, LG, JVC, Panasonic, Mitsubishi, Pioneer, Philips, Samsung, Sharp, TDK, Sony and Thomson. Both technologies have similar launch dates and offer similar functions. HD-DVD players will use a new type called HDMI cable for the transmission of digital picture and sound. This cable has multiple wires for both video and audio quality that ensures the clearest. Using a wire for both video and audio creates less organized than the previous technology. Players will also have s-video and component connections to offer a wide range of possibilities.

HD-DVD vs Blu-ray: A Primer

High Definition DVD (HD-DVD) vs Blu-ray is shaping up to fight a rival to the VHS versus Betamax format war of the early eighties. Looking like they have learned nothing from the DVD + / - RW debacle, the companies involved, whether in technology or content distribution industry (or in the case of Sony, both), are set to the from slug in the coming years. The price is the license fees paid to the format owners when the next generation of high definition DVD players and recorders start shipping in volume. As high definition television becomes more popular, consumers will want a recordable format that has the capacity to hold at least a few hours worth of HDTV content. Both Blu-ray and HD-DVD were developed in response to the anticipated need for an HDTV recording medium and provide quality content that would match the expectations of HDTV-owner clients. Moreover, film distribution companies money if they all titles currently available on DVD in one or both of the new formats and to persuade consumers that they really have to throw the DVD collection that they have time and money and start building again with the release of new high definition versions. Instead of being together and agree a format for high definition DVD, the industry has to split and produce two different versions. In the red corner is Toshiba, which developed HD-DVD and has signed numerous film companies as supporters, including Warner Bros., New Line, Paramount and Universal Pictures. In the blue corner, is, if you'll pardon the pun, Sony's Blu-ray. Sony plans to Blu-ray as the format for the next generation of PlayStation and has signed Disney and MGM and 20th Century Fox is expected to add to the list. Currently the major Hollywood studios are split down the middle with almost exactly half of them in each camp. HD-DVD developed by Toshiba and NEC and has the support of the influential DVD Forum, whereas Blu-ray is supported by Philips, HP, Sharp, Pioneer, Panasonic, and Sonic Solutions. Microsoft stands to benefit the format succeeds as the Windows Media 9 video codec has been approved for use in HD-DVD and Blu-ray content. Apple's H.264 codec has also been approved for both Blu-ray and HD-DVD.
