The Inclusion of HDTV With The LCD Technology

By John Terry Santiago


HDTV is actually a kind of television that is used the high level technology that could provide some similar quality with the 35 mm picture quality. This kind of television used a new digital transmission, unlike the older TV that is used the normal analog signal. The analog signal is still used on some countries, because on those countries the owner of the HDTV is still just a minority. But sooner or later, all the TV in the world must be HD ready. HD ready is an assurance of quality and technology for the TV you own. Some people even buy the HD ready TV without even knowing what the HD is on that HD ready term exactly. Well, HD is term used for high definition.

It's really different than the older knowledge on HD that meant Hard Disk for the computers. HD in this article says about the formats of video that a TV could support. When a kind of TV is really HD ready, then that particular TV can shows the video from the highest definition format, or for making it short you can watch the theatre kind of film right in your home. Ever since the invention of the HDTV, the term of home theatre has finally found its meaning. The movie lovers really welcome to this high definition television invention because their passion of watching movies could be satisfied greatly by this television.

Historically, HDTV was developed through series of innovation from the analog video systems that were usually adapted in many TV channels in the middle of twentieth century. This analog video system is considered not being able to accommodate the complex decoding signal of televisions that time. Therefore, the use of analog system was left as many researches tried to find another alternative to overcome the complexity of the decoding signal. Then it came what was called the digital compression. This technology was apparently still adapted from the old analog system. However, this technology can give better performance. The first standard HDTV was started to apply all over the world. Many researches all over the world agreed to set a standard ratio for this technology.

HDTV will afford the performance of 720p or 1080p videos with perfect ratio. You will not be disappointed because you can watch your favorite actors do full of effects scenes. You even do not need to sacrifice your pleasure by accepting the annoying black bars under and above the screen of the movies. In the lowest point, high definition TV has at least twice linear frame resolution compared with traditional SDTV. The smallest details will be captured perfectly by 16:9 aspect ratio for images.

Since Japanese TV station, NHK, started its development effort of HDTV, it has become the main stunning phenomena for the world's home entertainment. Since then, many television channels are competing to provide the audiences with HDTV video format to give more reality on the screen. Although not all television stations apply the high resolution format for the video, for advanced countries with advanced societies, this thing becomes a main concern and consideration. What make people like this kind of TV are not the impressive price and the prestige of having the TV; it is because the TV can give a real landscape of the world captured in video. The sensation of watching the scenery of the natures only from home is really amazing. Surely HDTV will give perfect rest and relaxation for people.
