How can I choose the best ATSC TV?

The

Advanced TV Systems Committee (ATSC) is responsible for digital standards that have replaced the previous NTSC analog standards in the US, Mexico in Canada and selected other countries. Most high -resolution TVs (HDTV) in these countries are now coming up with ATSC tuners. Selection of the best ATSC TV will depend on many factors.

The first consideration is the solution. If you want to understand this option better, first consider two types of HD broadcasts: 720p and 1080i.

and 720p broadcasts include 720 vertical lines and 1280 horizontal lines for a total resolution of 720x1280. "P" means progressive, with scanning lines sent okay, one line for the next. TV ATSC 720P ATSC displays the HD 720p signal, which means no conversion is required. If the TV is 60 Hz, it restores the display 60 times per second and gradually paints each line from top to bottom. TV 120 Hz or 240 Hz will paint 120 or 240 times per second, respect. This reduces "blur" in fast action scenes, jaKO is a sport, and also reduces the "blockage" in slow pans. Most HD sports are broadcast in 720p.

and 1080i broadcasting is a higher resolution with 1080 vertical lines and 1920 horizontal lines for a total resolution of 1080x1920. "I" means that the signal is transmitted interconnected, with two passages having a full screen. The first pass or frame paints odd lines, the second, even lines. Because it can cause artifacts in fast action scenes, 1080i is usually reserved for natural documents, travel protocols, movies and other programs that are oriented to the scene. TV 1080P ATSC integrates these two images internally to gradually display the image.

both HDTVS shows broadcasts in its native resolutions. The TV 720p TV takes the 1080i signal and constructs it to 720p before displaying. TV 1080p will have a 720p signal and up-convert to 1080p. The quality of up-converter or down-convertor (calledAná scaling ) becomes very important in watching programs that are not in native TVS resolution. For example, 720p broadcasts will look better on the HDTV 720P than on the 1080p set with a bad converter. .

If you plan to connect a HDTV computer to play or surf on the web, a higher 1080p TV resolution is comparable to a computer monitor, while the PC display will look Fuzzy on the 720p set. Higher resolution is also required to obtain the full benefits of Blue-Ray® DVDs, which have a resolution of 1080p.

brightness and contrast are two important considerations when choosing the best ATSC TV, but these measurements are not standardized, so it is unreliable to compare brands or models only by specifications. In general, higher numbers are better, but your eyes are Judge.

plasma and LCD technology have their pluses and minuses. Plasma TVs have darker, true blacks and the reputation of the overall truthRoyal colors, while LCD set out to achieve true blacks and provided beautiful pictures. LCD LED TVs are more expensive in this respect, but better than LCD. Plasma TVs do not apply to action scenes, although LCDs with faster refresh frequencies also close this gap as well.

At the disadvantage, plasma TVs have a highly reflective screen, which is best borrowed for screening without windows. LCD TV can be comfortably viewed against windows, open doors or lamps without reflection. LCD TV also uses less electricity than its plasma equivalent.

Choosing the optimal size depends on how far you sit from ATSC TV. There are several online graphs that can be used to determine the best screen size. The less fits back, the less the eye can detect the difference between stronger pixels 1080p and ts that reduces 720p. However, if you plan to sit relatively close to a larger screen, you can benefit from selecting ATSC TV 1080p.
