42k in 4K (Elemental stream Osaka marathon in Ultra HD)

Elemental Technologies have announced that it successfully supported the world’s first real-time 4K Ultra HD high-efficiency video coding transmission on Sunday when it streamed the Osaka Marathon. K-Opticom Corporation, a telecommunications operator, pioneered the workflow for the occasion and used Elemental video processing to deliver live coverage of the eight-plus-hour race.

“4K and Ultra High Definition will be very important, especially for live sports in the coming years, and HEVC compression will be critical to making 4K cost effective, reach multiscreen devices and not use too much distribution bandwidth,” says Tom Morrod, research director for consumer electronics and video technology at IHS. “With the upcoming World Cup and Winter Olympics, the industry needs successful real-time demonstrations of 4K video delivery and HEVC.”

Also in support of the event, K-OPT used Elemental video processing to provide live streaming of marathon coverage to PCs, smart phones, tablets and other connected devices. K-OPT was a presenting sponsor of the race.

With four times the resolution of high-definition (HD), 4K content presents a challenge to traditional compression approaches such as MPEG-2 and advanced video coding in terms of the bandwidth required to deliver a smooth and immersive viewing experience.
