General description

’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 the variety of SHV equipment that is still being used today.

Japan Broadcasting Corporation (NHK) has conducted R&D on the UHDTV television format, which is called Super Hi-Vision in Japan. 8K SHV boasts a resolution of 7680x4320 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 to the SHV catalogue. From December 2018 the new 4K 8K satellite broadcasting began in Japan, and we are creating a steady stream of innovative equipment and technology from an intensive focus in R&D.

What is 8K Super Hi-Vision...

Production equipment that produces 8K contents is being developed by each company including Astrodesign. They already have a range of equipment such as camera, monitor, projector, recorder, signal processor, editing device, transmission device.

8K has great potential in various industrial applications besides broadcasting. In addition to enjoying images, it is possible to utilize the overwhelming amount of information to provide a variety of data to machine eyes and computer eyes. We believes that combining the latest technologies such as AI, IoT, and 5G with 8K will open up unlimited possibilities in social infrastructure, big data utilization, medical field and so on.
