HDTV - high-definition television: it is something that has been discussed for some time now, however not everyone has a strong sense of what it is and why he or she would want to have it.
Digital image processing is a technology that began in earnest during the 1970's, when Japanese technology companies began to explore the concepts of HDTV. The Japanese TV manufacturers were exploring ways to improve the picture quality of the television image, as a way to find more customers for their television products.Analog television has been with us since the inception of television broadcasting. Analog is the old way of processing a television signal.While it is true that you do not need to upgrade your television from the analog format to the new digital format, you might seriously consider doing so anyway.Because all television stations will be required to broadcast a digital signal after February 17, 2009, many viewers are beginning to ask a lot more questions about how the new digital age of television will affect their personal viewing experience. They want to know whether or not their television set will be compatible, whether or not they will have to replace it, and what steps they will have to take in order to keep watching their favorite shows.3. Sound QualityThe newer digital technology is all about Lines Of Resolution. With more lines of resolution, the viewer will receive more image information, therefore bringing the viewer much more picture clarity and detail.2. Aspect RatioIn 1995, after considerable opposition from the television broadcast industry, the U.S. Federal Communications Commission officially set the standard for completely digital HDTV broadcasting system. This put into motion the events that are just now coming to fruition, with the rollout of the new Digital Television broadcasting system.* Analog Television - 330 Lines of ResolutionUnderstanding The Three Facets Of The New Digital TechnologyWill My Analog Television Stop Working In 2009?When it comes to plasma television. Your producing frame sequential images. A right then a left. A plasma television starts with a pixel that makes its image, then erases it and then produces the next one. So when these TVs create a right, left, right, left picture, There�s a small chance of getting distortion between the left and right image.In 1998, when the first HDTV's became available to the buying public, the Headline News newscasters were joking that with the rollout of HDTV, we the audience would be able to see every blackhead and blemish on their faces. Of course, they were probably correct in that assumption. The detail of the HDTV-signal is absolutely amazing.Simply plug any HDMI® device, including Blu-ray / DVD players, game consoles, smartphones and tablets, into the Aerobeam WirelessHD transmitter and connect the receiver behind the TV. No extra configuration is required. ZyXEL's Aerobeam WHD6215 adapters provide full 1080P video playback, including 3D, with no lag or loss in picture quality. It also supports 7.1 surround sound audio for the highest-quality A/V (audio/video) experience available.* DVD's - 480 Lines of ResolutionFor LCD HDTV they have to refresh their picture very quickly. LCD TVs light source works in a way like little gates that open and close to let the light source in it. It takes sometime for those tiny LCD molecules to change their state, This may cause a problem when the right eye sees part of the left image and the left eye sees part of the right image.Their our two different light sources inside the movie-theater, 2 different polarize on 2 different projectors. one for the right eye and 1 for the left eye. So as long as you have a pair of eye-wear which have the same polarity as the left and the right, then were ensured that the left image goes to the left eye and the right image goes to the right eye.The third factor connected to the new HDTV-format is Sound Quality. In fact, most HDTV programming will carry with it Dolby Digital 5.1 surround sound, as frequently heard on DVD's. So long as you have a surround sound unit attached to your television set, the surround sound will enable to the television viewer to be immersed in the sound, so much so as it often feels as if you are in the middle of the action happening on your television set.When the Japanese rolled out HDTV on the Japanese mainland, the lines of resolution numbered 1080. To put this into perspective, the standard analog TV signal exhibits 330 lines of resolution. This makes it more than clear that the original analog HDTV format really was a real issue for television broadcasters in the United States. To produce a resolution of 1080 lines on a system designed for 330 lines would have literally required three times the bandwidth of the current analog system.Based on the industry's WirelessHD technology standard, ZyXEL's Aerobeam WHD6215 is architected and optimized for the sole purpose of wirelessly streaming HD multimedia. It leverages 60 GHz millimeter wave technology, providing the necessary bandwidth for multi-Gigabit data rates, which are required to wirelessly stream reliable, uninterrupted HD video and audio. The 60 GHz spectrum also eliminates interference from other wireless technologies, such as popular 802.11x standards.If your current television does not have a logo on its front that indicates DTV (Digital TV), EDTV (Enhanced Definition TV), or HDTV, then your television set is an analog TV.In addition, ZyXEL's North American Channel Program offers industry-leading incentives with its full line of products. ZyXEL's North American headquarters are located in Anaheim, California. http://www.us.zyxel.com .Researchers soon understood that they would need to push at least part of the television signal in a digital format to make sure that HDTV could be transmitted within the limits currently allotted to the television broadcasters. By the time they had finished their work, the Grand Alliance had created a system that was 100% Digital.Here are the standard television resolutions:Television technology took a big leap in the 1960's with the transition from television tubes to circuit boards, but that conversion failed to bring with it any major strides in the quality of the television picture.PRESS CONTACTS: Jake Sailana ZyXEL Communications 714-632-0882 x 276 Email Contact Brittney Wolff / Lauren Grassetti LEWIS PR for ZyXEL 619-677-2700 Email ContactNow that we are quickly approaching the end of the analog-television era, the cost of HDTV television sets has fallen considerably. Whereas five years ago, the average HDTV cost in the range of $3-4,000, the cost of most HDTV's has fallen to under $1200 today. After February 17, 2009, the cost of HDTV should drop again, making it much more affordable to the general public.Another factor connected to the new HDTV-format is the Aspect Ratio.There is a caveat to this chart though. The minimum requirement of the FCC is that broadcasters must produce a minimum of 720 Lines of Resolution. As a result, some broadcasters like ABC chose the 720-resolution, and yet they can still legally call their programming standard, HDTV.Other broadcasters like PBS opted for the higher 1080 format. Good for them.When you buy TV, it only has a simply single light source. So you'll have to create a right picture and a left picture in 2 various ways. We do this in a frame sequence kind of way. The projection image produces. What we have to do though for it to synchronize with our eyes is we have to use a pair of glasses that is synchronize to the television. So the television will tell the eye-wear... I'm showing you the right image. So therefore the lens of the left side of the eye-wear will become transparent, the right lens will be going dark. So therefore the left image is being seen by the left eye. The reason why you may not notice the flashing is because its done really fast (usually over 100 times a second).* HDTV - 1080 Lines of ResolutionAlthough color-technology was first introduced to audiences with the release of The Wizard Of Oz in 1939, color television did not become mainstream until the late-1960's. And although the technology of color was mainstream, black-and-white televisions were still being manufactured and sold well into the 1980's.Fortunately, this transition will be a bit quicker than the conversion from black-and-white to color. Under the FCC rules for the transition to digital television, television manufacturers were required to include a digital tuner in all television sets manufactured after March 1, 2006.1. Lines Of ResolutionHow To Identify If Your Television Is An Analog TVAlthough most television stations have been broadcasting a Digital Television Signal now for a few years, analog television owners have been none the wiser. But that will all change on February 17, 2009.In Conclusion...* VCR's - 240 Lines of ResolutionWhile Americans were busy playing with building the computer industry, the Japanese were hard at work trying to build a better television set. The first HDTV systems developed by the Japanese still relied on the old analog system of sending a broadcast signal to their televisions, but they were still able to produce a better television viewing experience.* EDTV - 720 Lines of Resolution1. Subscribe to a cable television service (and use their digital television converter);The WHD6215 will be available from all ZyXEL authorized resellers and e-commerce partners at its approximate street price of $199.00.In 1993, a consortium of American researchers and manufacturers (known as The Grand Alliance) joined forces to find a way to bring HDTV-quality to the American public, while keeping the bandwidth requirements of broadcasters within the existing limits.When initially introduced to the U.S. Government, the new HDTV system produced a myriad of concerns, which included the issue of an analog HDTV-system needing more bandwidth than what was currently allotted to the television broadcasters.
If you have any lingering doubts about the better HDTV standard, all you need to do is to visit your local television store and see for yourself just how awesome of a picture HDTV actually produces. Just as Dolby Digital Surround Sound enables the listener to feel as if they are in the middle of the action on the television, HDTV permits the viewer to feel as if they are standing in the same room as the actors, on the sidelines at the football game, or on the same beach as the models - it really is that good of a picture.
