Elemental to provide Japan’s first realtime 4K HEVC transmission with K-Opticom

Elemental Technologies will deliver a first in Japan, when telecom operator K-Opticom Corporation uses the company’s video processing for a live 4K Ultra HD HEVC transmission. Elemental Live systems will power video streaming of the Osaka Marathon on 27 October in a K-Opticom-designed trial workflow.

“With resolution four times that of HD, demand for 4K content on high-quality, large-format screens is increasing,” said Takao Fujino, president of K-Opticom. “The advanced K-OPT optical fibre network combined with the power and flexibility of Elemental’s software-based architecture is vital to meeting this demand and to enabling this unprecedented experimental transmission.”

The Japanese telco is using Elemental Live systems to provide HEVC encoding of 4K/59.94p material acquired from Sony PMW-F55 CineAlta 4K cameras located at the midpoint and finish line of the racecourse. Each camera will be mounted with an AJA Ki-Pro Quad, which will send source content to Elemental systems via live 3G-SDI interfaces.

“The stunning images and high quality of 4K are best showcased at a world-class sporting event like the Osaka marathon,” said Keith Wymbs, VP of marketing for Elemental. “Elemental’s award-winning H.265 codec makes it possible to smoothly transmit 4K images across wideband networks provided by operators like K-Opticom.”

Elemental video processing systems will encode live content in realtime HEVC at 4Kp30 and stream video over K-OPT optical fibre networks to an NTT Docomo decoder with final rendering on an 84-inch Sony 4K Bravia TV. The public will be able to view 4K live coverage of the marathon in a K-OPT exhibit located Osaka.
