Topic 1
“8K” is the International Specification for UHDTV(Ultra High Definition Television) led by NHK(Japan broadcasting corporation)
• HDTV – 2K resolution(1920×1080)
• UHDTV1 – 4K resolution(3840×2160)
• UHDTV2 – 8K resolution(7680×4320)

Topic 1
“8K spec” is NOT defined by following the roadmap of the high resolution competition for the sensor/camera, but is defined by the study of
“Human Science”

Topic 1
To get: “Sense of being there” and “Sensation of realness”
Like being there Like watching a real object
