Knowing more in HDTV

Though HDTV is very sharp and clear in its quality as of today, its quality is bound to improve over the next few months and years. The advent of HD DVD players allowed consumers who already had 1080p High definition television sets to be able to view a full HDTV image. The following standards are considered High definition viewing,

1280×720p @ 24fps (frames per second)
1280×720p @ 30fps
1280×720p @ 60fps
1366×768p @ 30fps
1920×1080p @ 24fps
1920×1080i @ 30fps
1920×1080p @30fps
These numbers refer to the number of pixels on screen , vertically and horizontally and the frames per second which tells us how often the screen is refreshed. This rate is generally so fast that the screen refreshes before the blink of an eye. The curent HDTV’s being sold are of the 1920*1080p models, these being the highest definition possible as of date. This however is leading to some confusion as noone is curently broadcasting in the 1080p format, which means that the first half of the screen gets refreshed before the second half.

1080p refreshes the screens at one go and is available with the new DVD players entering the market. However there are arguments whether 720p which is a progressive scan is better than the 1080i interlaced scan, but this only addresses one feature of the quality issue. The main issue is the pixels, the more the pixels the better the quality. The best resolution till recent times was 1366*768, but the new 1920*1080 offers a better resolution, but that does not imply that they offer better picture quality.
There are other features important to picture quality such as deep blacks, contrast, brightness, color and quick refreshing of the screen which can be decided by the viewer at the time of purchase.

There are many types of HDTV’s in market today which include Plasma, LCD, rear projection front projector, SED, LcoS etc. There are many options in the market, the best advice to the consumer is to do your homework before entering the store.
