Ultra High Definition Video

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

• Resolution: 7,680 × 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 had to build their own prototype from scratch. They used an array of 16 HDTV recorders to capture the 18-minute-long test footage. The camera itself was built with four 2.5 inch (64 mm) CCDs. According to people who saw a demonstration, UHDV is so life-like it could cause motion sickness if the camera moves too much.
