HD TV Specifications -2
HDTV is slowly becoming the standard in our world today. Rumor has it that by the year 2012, HDTV will have completely replaces ancient analogue television sets, so it’s no surprise that you should your time and shop around for a good one. Before that though, much research is needed. Two of the more important specifications to look for are the type of connection that will be used, and the “Contrast Ratio.”
The contrast ratio plays a big role on how well the picture displays. Another role contrast plays is how easily and clear the details display on the screen. While shopping around for a good HDTV, you’ll notice that the screen contrast ratio numbers vary widely, even ratios of televisions in the same price range.
Often times, two sets of numbers you’ll come in contact with are 3000:1 and 800:1. These numbers are the ratio between white to black colors on the screen at one time. Having said that, 3000:1 means the white colors are 3000 times brighter than the black colors. Likewise, 800:1 means that the white colors are only 800 times brighter than the black colors. In easier terms, the lower the contrast ratio number, the higher likelihood the coloration will be much different than the video source, versus a higher contrast television.
Another option to consider when it comes to buying an HDTV is the type of connection that will be used. The most popular type is called HDMI, which is short for High-Definition Multimedia Interface. HDMI is a 19-pin connector that supports 10.2 Gigabits per second at 340 Megapixels per second.
Another type of popular connection is the type used mostly in France, called SCART. SCART is an acronym that means Syndicat des Constructeurs d’Appareils Radiorécepteurs et Téléviseurs. The 21-pin SCART connector appeared originally in 1977 on French television sets, and it became the standard in January of 1980.
