The high-definition television (HDTV) is the highest form of digital television. So all HDTV is digital, but not all digital TV (DTV) is high definition. HDTV has a ratio of 16:9, similar in appearance, this is a movie screen. HDTV has a number of advantages over the old format of analog TV – big screen and its resolution.
The widescreen format is good for our eyes – we see pictures of large rectangular display better than the old square. Basically, our eyes cannot see the left/right with respect to/from. The widescreen, we also have the scene on the screen, which is ideal for sports and movies.
“720p VS 1080p”
The number 720 and 1080 are the number of lines of vertical resolution, while the letter p is progressive scan or non-interlaced.
“Progressive” simply means that every time the image is updated (between 24 and 60 times per second, depending) format, you see the whole picture. “Interlaced” on the other hand, the entire second row shows the pixels with a refresh, but alternating odd and even lines that appear to the human eye can see the whole picture.
Resolution of 720p and 1080p HDTV (the number of points/pixel full-screen HDTV). 1080p HDTV is 1920×1080(2,073,600 pixels), while 720p HDTV has about 1280 x 720(983,040 pixels). 1080p because nearly twice the resolution of 720p has adapted to produce a much clearer picture.
The most important thing for the resolution of HDTV is understood that 720p and 1080p HDTV monitors have the same physical size. For example, a 52-inch 720p and 1080p HDTV 52 “HDTV both have the same size (52″ diagonal). The difference is the set 1080p must correspond to approximately 2,073,600 pixels in the same space that corresponds to 983,040 pixels 720p. This means that the pixels in a 1080p HDTV should be less than the pixels of the same size 720p. Since the pixels are smaller in HDTV 1080p, 1080p on the display at retail.
The world of high definition television (HDTV) is a new technology and entirely new concepts. One of the most compelling slogans is “1080p” the term for the highest possible resolution on an HDTV.
