Japanese NHK develops a compact 8K Ultra HD camera

The Japanese public broadcaster has also unveiled an HEVC/H265 encoder for transmission in Ultra High Definition format.

NHK camera in 8K

The Japanese NHK, in collaboration with technology companies in the country, is developing equipment and solutions to carry out the transmission of content at 8K Ultra HD resolution. One of the new features now presented by the company is a light and compact camera capable of capturing images in Ultra High Definition format, with a resolution of 7680x4320 pixels.

All circuits, including the 33-megapixel image sensor, are contained within a system of just 10 square centimeters. Precisely this reduced size allows the use of smaller and lighter objectives.

In addition to the camera, developed together with Astrodesign, NHK is also investing in a compaction system for transmission and playback of content in Ultra High Definition format.

In collaboration with Mitsubishi Electric, NHK has created the first encoder between HEVC and H265 systems. In this coding model, the Ultra HD image is divided into 17 tracks and compressed at 85 Mbps, making satellite transmission possible.

NHK plans to broadcast the first tests in 8K resolution over its network in 2016.
