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.

HDTV-Blu-Ray vs HD-DVD - The Beginning Of A New Rivalry?

Now we have more and more HDTV's HDTV has become a battle of Blu-Ray vs. HD-DVD. This resembles past battles such as VHS vs. Beta in the '80 's. The main similarity with the two is the wavelength on which they are read. In the past, CDs and DVDs using lasers that were about 650nm long, while the newer, HDTV-Blu-Ray vs. HD-DVD, both use the ones that are 405nm long. Believe it or not that makes a huge difference in quality and space. Besides this basic information on the amount of information that can be stored on this is much better than in the past. Older DVD's or what are called standard DVDs can hold around 4.7 gigabytes of information. This can carry over a two hours long film with a few extras that will play well on regular TVs. But it will not allow for the large view at higher resolutions. But HDTV with Blu-Ray vs. HD-DVD can hold two more. Although both can save more and therefore better for the new HDTV's, there is a big difference. In the battle of HDTV-Blu-Ray vs. HD-DVD, Blu-ray can actually hold more information. HD-DVD is usually up to 30GB, depending on what kind of layers on the disk. While Blu-Ray can hold up to 50GB, again depending on the number of layers on the disk. This difference in the room can not say that much of the average movie watcher, however. Another important difference when it comes to HDTV Blu-Ray vs. HD-DVD is the cost of making them. The HD-DVD seems to be cheaper to produce. This means that Blu-Ray costs more to produce and able to raise prices for consumers. This also means that HD-DVD is far lower shelf prices. Although each will not play on other players, they can both play on older DVD players. At this point in the battle it seems that HD-DVD is better for the computer used at home, while Blu-Ray is better for movies and such. As you can see there are a few things to consider when it comes to work to HDTV Blu-Ray vs. HD-DVD. But in both cases there are some pros and some cons. At the end is really up to you what works best for your personal needs. Based on the above information you should be able to better and more informed decision. Only time will tell which one will ultimately win. Check out for articles about http://www.hdtvland.org/ and sharp HDTV Samsung DLP HDTV.
