First up check out the new prototype 8K Ultra High Definition shoulder mount camera from NHK shown in this video from DigInfo News. We have seen a few box and studio versions of the camera over the years but this is the first 8K camcorder that is compact and portable.
Earlier in May NHK successfully tested an 8K transmission experiment outdoors by sending a UHDTV video signal using two channels on the UHF band. The NHK 8K signal was compressed, encoded, and transmitted at around 183.6 Mbps then received at a distance of 4.2km away with no errors or drop outs in video or audio when the signal was restored.
Next up so you are up to date on UHDTV or SHV as NHK calls it is the news that the ITU has defined the parameter values for two formats of ultra high definition TV (UHDTV). These are the 4K and 8K UHDTV formats. They are constructed as multiples of the 1080p1920 format in ITU-R Rec. 709.
Lieven Vermaele EBU director of technology and development: “Facilitating these superb pictures hasn’t been made possible overnight, this represents over ten years of technical discussion and experiment. It has been a long journey, but we are delighted to have arrived at this point and pleased that the EBU has been able to make a contribution to broadcasting history.”
Shot last year at the ITU in Geneva in October, David Wood (EBU) Deputy Director of Technology and Development explains what UHDTV is and why it is relevant. He covers the format’s definition, screen space, audio system and what it does for the audience. The video probably needs some updating because of the release of the Nikon D800 camera.
Lastly some more light reading on UHDTV with older posts when Cinescopophilia previous covered the NHK 4320X7680 8K 120 fps Super Hi-Vision CMOS Sensor HERE, and how Panasonic will record Super Hi-Vision with P2 Towers for the 2012 London Olympics HERE.
