You may have heard of HDTV but you could be puzzled by all of the new terminology. Perhaps you are a wedding videography company thinking about upgrading. Here's what you want to understand about HD.
The maximum resolution on a standard analog TV is 720 X 480 pixels, which is about 337,000 total pixels. HDTV is a component of the Digital TV specs which has many alternative video resolutions. The 2 main resolutions to be concerned about are 720p and 1080i. The "p" means progressive and "i" mean interlaced, in both resolutions each second has 60 frames of video.
Progressive resolution puts 60 full frames on the screen every second. Interlaced resolution puts 30 frames of only strange lines and then 30 frames of only even lines up each second. Some individuals find 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 big 2,073,000 pixels.
It is personal choice as to which resolution you like, the best way of finding out is to go down to your local retailer and look for yourself.
The sound on HDTV will sound better than it probably did on your analog television, some HDTV programs include Dolby Digital 5.1 surround sound, but you will need the relevant speakers to be well placed to milk this.
You will have to purchase a new HDTV. Some HDTVs come with inbuilt tuners, while others do not. The tuner converts the signal into something that your TELEVISION can recognize. HDTVs that do not feature a tuner are typically called "HDTV Ready." An HDTV without a tuner is worthless.
