What is High Definition Tv?

By: David Tanguay

Presently the highest level of resolution in TV viewing is found in HDTV. HDTV currently offers the clearest audio signal. Today's TV viewing has a new format and standard, which is with digital programming. When viewing HDTV, images appear so clearly that you will feel as if you are there viewing the image in person, rather than over a TV screen.

HDTV range in various styles and prices, which take into account the technology used and the TV's screen size. High definition broadcasting signals are already available, however you will need a built in tuner and an antenna programmed for decoding the HDTV signals. The normal one to one display point of an HDTV image needs an input format of 1081i that displays 1920x1080 pixels, for best results.

Any non-broadcasted signals must be purchased from a cable or satellite provider. To learn the pricing and the programming of these HDTV non-broadcasted signals you must contact your local provider.

HDTV requires three significant occurrences in order to deliver high quality TV screen viewing, and those are an HDTV set, a method to receive HDTV signals; which can include an antenna or a connection for satellite or cable service, as well a source that is transmitting HDTV signals by means of a local station or a satellite or cable station.

The integrated HDTV has a digital tuner built in to its programming. When a television station is broadcasting in high definition, you will be able to attach an antenna to the set and tune into their broadcast.

The HDTV-ready set is a monitor that does not contain a HDTV tuner. They often have a NTSC tuner, which enables you to watch analog TV. HDTV ready sets are less expensive and give you the option of adding an HDTV receiver at a later time.

Choose an HDTV set that has a native resolution that matches the signals you would normally use more often. Whether that is the highest possible resolution or the highest possible progressive frame rate, the choice is up to you and what you feel most comfortable in viewing.

Make sure that the HDTV that you buy is user friendly with the equipment you already have at home or if you need other components or adapters. Nearly all LCD and plasma TV's are HD ready and can support the programming of high definition that is supplied by an external component receiver.

There are four major TV networks that broadcast their own type of free HDTV programming. With the right antenna, you should be able to receive their broadcasted signals. However all channels do not offer HD programming therefore there may be need for additional components to be able to get better reception from standard and enhanced definition TV screens.

Another thing to keep in mind is when choosing HDTV that future technology could very possible make available the use of more components and accessories to be purchased for HDTV viewing future broadcast signals. You can always wait to see how these new technological services turn out and then purchase programming.
