Super Hi-Vision, also known as Ultra High Definition Video, UHDV, Ultra High Definition Television, UHDTV and UHD is a digital video format, currently proposed by NHK of Japan.

For the 2016 Olympics Game in Tokyo, Japan will carry out test broadcasting in Super Hi-vision in 2015, and Japan is expected to have super hi-vision broadcasting within a decade from then.

An SHV image has an unfathomable 7680x4320 resolution, a complete four times that of 1920x1080.

NHK developed a Super Hi-Vision camera equipped with 8 megapixel CCD image sensors that can take 4k x 8k images. In the field test, it sent the two cameras to a sea park and sent baseband signals without image compression using an fiberoptic network formed by multiple network companies.

The signal of the total 24 gigabits per second was divided into 161.5 Gbps HD-SDI signals to sent using the DWDM (dense wavelength division multiplex) method.

Features of Super Hi-vision
- The system uses a video format with 7680 x 4320 pixels (16 times higher than standard Hi-vision, NHK’s HDTV system) . This world’s first video system with 4000 scanning lines delivers ultra-clear, realistic three-dimensional images that can be achieved only by ultrahigh-definition technology.
- The individual scanning lines are not visually noticeable even when relatively close to the screen, reflecting the high resolution of the system. What’s more, a wider viewing angle conveys a stronger sense of a reality.
- The new 3-D audio system with 24 loudspeakers dramatically enhances presence.
