What Is HDTV Plasma TV

With so much hype about high definition television or HDTV enabled sets, everyone wants to know What Is HDTV Plasma TV. High-Definition Television (HDTV) is the vision of the future and the many TV broadcasting stations will soon be beaming prime time programmes in this thrilling new format.

In plain language, HDTV can be said as a high definition television, a means of digital broadcasting that result in high-quality crystal clear pictures combined with Dolby Digital surround sound brought to your sitting room.

High definition television also uses the same amount of bandwidth - 6 megahertz as used in the present conventional broadcasts.

However, HDTV can transmit more than six times the information as the conventional “analog” system. This means that the quality of the picture and the sound are of exceptionally good quality.

If you want to watch the broadcasts that are aired in the HD format, you must have a high definition tuner and monitor or screen in order to decode the HD TV signals and display them accurately on your screen.

Most TV stations broadcast their programmes in the standard format. But, this situation is fast changing and soon you will have TV broadcasts that will be done in the HD TV format only. 

Your standard television set cannot receive and translate HDTV signals that are being broadcast.

• When you want to step up to watching HDTV, you'll need to get a new high definition enabled TV set.
• The HDTV signal is digital resulting in crystal clear, noise-free pictures and CD quality sound.
• When you watch such broadcasts on your TV screen it will be like watching it in a cinema with the modern sound systems.
• In fact, you will get the real theatre effect in your sitting or bed room.
• HD TV has many viewer benefits as well.

Most televisions today are manufactured in a 4 by 3 aspect ratio, which means the screen is 4 units wide by 3 units high. This is almost like a square.

But theatrically released movies are usually in a much wider aspect, taking advantage of the human field of vision, which is wider across horizontally.

HDTV signals are sent in a 16 x 9 aspect ratio, just like the wide scope of movies. HDTV's aspect ratio makes for a more immersive and intense viewing experience.

Resolution is a gauge of image sharpness on the screen that you are watching. The present conventional television contains about 480 active scanning lines resulting in a picture resolution of about 330 lines of resolution.

By comparison today's VHS VCR's have about 240 lines of resolution which is why VHS recordings don't look as sharp as the original picture.

However, the DVD's offer higher resolution typically on the order of 400 to 480 lines of resolution. For example, both the VHS and DVD formats have 480 active scanning lines but have different resolutions. HDTV offers resolution that is at least twice that of the conventional analog television. Therefore the pictures on an HD TV enabled screen are razor sharp.
