You have possibly heard of HDTV but you may be confused by all of the latest terminology.
The greatest resolution on a normal analog TV is 720 X 480 pixels, which is about 337,000 total pixels. HDTV is portion of the Digital TV specifications which has many diverse video resolutions. The two major resolutions to be concerned about are 720p and 1080i. The "p" means progressive and "i" mean interlaced, in both resolutions every second has 60 (or 50 in Europe) frames of video.
Progressive resolution puts 60 complete frames on the screen every second. Interlaced resolution puts 30 frames of only odd lines and then 30 frames of only even lines up every second. Some people discover that the interlaced video causes flickering.
The 720p video resolution is 1280 X 720 pixels, which gives 921,600 total pixels and the 1080i video resolution is 1920 X 1080, which gives a huge 2,073,000 pixels.
It is a personal option as to which resolution you prefer, the best means of finding out is to go down to your local retailer and look for yourself.
The sound on HDTV will sound in a superior way than it did on your analog tv, a number of HDTV programs contain Dolby Digital 5.1 surround sound, but you will need the relevant speakers to be capable to take advantage of the special sound.
You need to buy a new HDTV. Some HDTVs arrive with integral tuners, while others do not. The tuner converts the signal into something that your TV can distinguish and use. HDTVs that do not come with a tuner are commonly called "HDTV Ready." An HDTV not including a tuner is useless.
In addition it is possible to look on HDTV on your pc. You may do it with the assistance of a video card such as the ATi HDTV Wonder . This video card is sold with its own antenna to receive HDTV stations .The video card as well has inputs for cable and satellite signals. The advantage of this is that you can play and record any show you want on your computer.
