Sharp will mass production of 8K LCD TV next year
Currently, there is no strict specification standard for 4K resolution in the industry. As early as in 2012, the UN's International Telecommunication Union (ITU) adopted the 7680x4320 resolution recommended by Japan’s NHK TV as an international 8K ultra-high resolution. Super Hi-Vision (SHV) standard. In other words, 8K is the true meaning of Ultra HD resolution.
The Super Hi-Vision (SHV) standard is not only reflected in the resolution, but also in terms of color gamut, color depth, color gradation, gray scale, frame rate, standard viewing distance, viewing angle mode, and audio. There has been a huge leap forward.
The 8K's main specifications are:
Resolution 7,680×4,320 pixels (16:9) (approximately 33 million pixels per frame)
Color depth: 12 bits
Frame rate: 120 frames per second (progressive scan)
Audio: 22.2 channels
Bandwidth: UHF–8 MHz, 35~45 Mbit/s (RAI DVB-T2 Test)
8K video requires professional camera equipment
Although 8K can bring clear picture quality close to the limit of human eye recognition, the current 4K source still has some distance from us. Can we see the 8K source in our lifetime? Speaking of 8K 120fps transmission specifications, 8K resolution is approximately analogous to 33 million pixels, while 120fps refers to streaming video playback of 120 3,300,000-pixel images per second. This amount of data is very large. It is understood that even if the video in the 8K format is only one minute, it can occupy a full 194GB of space. With our current network or other video carrier, it is not enough to handle the huge 8K video capacity.
22.2 is very exaggerated In addition, the 22.2 channels of the 8K standard are even more exaggerated. They need speakers in the upper 9-channel, middle 10-channel, and lower 3-channel three-tier configurations, as well as two-channel low-frequency audio (LFE) speakers. Ten, nine, and three horns were placed in the horizontal position of the listener's ears, above and below the ears of the listener, and two subwoofers consisting of 36 small woofer units were also provided.
The good news is that Sharp will cooperate with ASTRODESIGN, a Japanese video equipment manufacturer, to combine Sharp's proprietary liquid crystal and camera sensor technologies with ASTRODESIGN's digital signal processing technology to jointly develop and support 8K video systems, including photography. Or make necessary cameras, video processing devices, monitors and other products.
If you can solve the film source problem, then the temptation of 8K TV is huge enough to spike any 4K TV product.
