Ultra High Definition Video - Definition and Overview

Ultra High Definition Video or UHDV is a digital video format, currently, proposed by NHK of Japan.

• Resolution: 7,680 by 4,320 pixels.
• Frame rate: 60 frame/s.
• 22.2-channel audio
  • 9 - above ear level
  • 10 - ear level
  • 3 - below ear level
  • 2 - low frequency effects

The new format is four times as wide and four times as high as existing HDTV with a resolution of 1920 × 1080 pixels. Because this format is highly experimental, NHK researchers have to scratch build their own prototype. For example, they used an array of 16 HDTV recorders to capture the 18-minute-long test footage. The camera itself was built with 4 2.5 inch (64 mm) CCDs. According to people who had seen a demo, UHDV is so life-like it could cause motion sickness if the camera moves too much.
