TV News Daily News: Ultra HD resolution advantages

UHDTV is an abbreviation of Ultra High Definition Television. It stands for "Ultra High Definition Television" and is the next generation of HDTV technology. In May of this year, the International Telecommunications Union (ITU) issued a proposal for "Ultra High Definition Television UHDTV" (or "Ultra HDTV") standards, arranging screens with physical resolutions up to 3840×2160 (4K×2K) and above. Ultra HDTV. This technology has a higher resolution than HDTV (High Definition Television), a larger viewing angle, and a stronger visual impact, which solves the problem of the loss of large-screen television details and the inability to truly restore them.

1. Four times full high-definition full-width HD video display is about 1 million pixels, FHD is about 2 million pixels (1920×1080), and UHD pixels can reach more than 8 million. Ultra HD (UHD) pixels are 4 times more full HD (FHD), with 6.22 million more pixels.

Extremely high resolution brings incredibly detailed display effects that feel comparable to Apple's IPHONE4's "Retinal Screen." The original human eye is less than or equal to a distance of 0.3 meters, the limit resolution is 300PPI, Apple Iphone4's retinal screen is 1.09 times higher than the human eye resolution threshold PPI. Skyworth Ultra HD (UHD) is 2 times higher than the normal distance (4 times the size) of the human eye's distinguishable limit PPI and nearly 2 times higher than Apple's standard.

2. If the screen is too large, the human eye will see the pixels when watching the HDTV at the same distance and the same size. Looking at UHD Ultra HD TVs at the same distance, you can't see the pixels at all. After testing, it was found that the perfect size of an HD TV is 32-37 inches, while the perfect size of an FHD is 42-55 inches, and only UHD Ultra HD TVs can be perfectly presented for oversized TVs.

3, UHD single-chip lossless ultra-high-definition UHD single chip can achieve lossless decoding of the original 4K × 2K film source, so that the real process of ultra-high-definition, so that the real process of ultra-high-definition.

4, 1080P/1080i smart enhanced 2.89 times ultra-high-definition cloud TV is thanks to 4K ultra-high inventory chip, can be compatible with 1080P/1080I full HD film source, through intelligent computing, in the space axis plane image tracking compensation, each pixel Around the insertion of four pixel points, accurate reproduction of horizontal and vertical line field information, to enhance the amplitude of 70%, the overall increase of 2.89 times, to achieve approximately 4K ultra high-definition display.

Optic fiber clousure dome type is applied in the junction and protecting of the fiber.It can be place with the aerial cable or buried in earth or put in the pipeline.The outer part and the fusing part of the clousure are made of the project plastic with the virtue .
   Fiber Optic Splice Closure is a Fiber Infrastructure System Technology. It is the environmentally sealed enclosure for the fiber management system that provides the functions of splice and passive component integration in the external network. Single-ended design. Base and dome are sealed with a clamp and O-ring system, 16 round entry/exit ports for drop cables and 1 oval port for looped cable.
