8K Super Hi-Vision(SHV) is a next-generation video technology that provides an overpowering sense of realism and strong visual impact. ASTRODESIGN has been working on 8K SHV technology since its very beginning, resulting in the development of a variety of SHV equipment still being used today.
The Japan Broadcasting Corporation (NHK) has conducted extensive research and development on the Ultra High Definition Television (UHDTV) format called Super Hi-Vision in Japan. 8K SHV boasts a resolution of 7680×4320 or 16 times the pixels of the current HD format.
This video is viewed at 60fps in progressive video format. The feeling of immersion is impressive, with objects being displayed with a far more natural sense of depth.
ASTRODESIGN has been collaborating with NHK since the advent of SHV, leading to the development of many necessary pieces of equipment added to the SHV catalogue. From December 2018, 4K/8K satellite broadcasting began in Japan, and our company has been creating a steady stream of innovative equipment and technology with an intensive focus on research and development.
What is 8K Super Hi-Vision…
Aspect ratio: 16:9
Frame rate: 60Hz progressive
Audio system: 22.2ch
Regarding spatial resolution, 8K Super Hi-Vision’s is 7680×4320, 16 times that of current HDTV (1920×1080), and its 60 frames per second progressive scanning makes its timing resolution twice as much as current HDTV 30fps. Moreover, UHDTV defines appropriate viewing distance as 75% the vertical length of the display. People can enjoy a much closer position to the display than with HDTV and experience a 100-degree wide-angle view. These specifications make UHDTV quite immersive.
Not only the video, but 8K SHV’s audio is top-quality as well. A 22.2ch audio system includes twenty-two audio channels and two low frequency channels. The system includes three layers with 9 speakers at the top layer, 10 at the middle, 3 at the bottom, surrounding viewers from all directions, as well as two woofer speakers in front. This system provides a real-world audio experience.
Production equipment used to create 8K content is being developed by a variety of companies including ASTRODESIGN. We already have a range of 8K equipment including cameras, monitors, projectors, recorders, signal processors, editing devices, and transmission devices.
8K has great potential in various industrial applications other than broadcasting. Not only can people use 8K to enjoy high-definition imaging, but by utilizing 8K’s overwhelming amount of information, it is possible to provide various data to the eyes of machines and computers as well. We believe that combining the latest technologies such as AI, IoT, and 5G with 8K will open up unlimited possibilities in social infrastructure, big data utilization, medicine, etc.
