Dolby Demos Live Ultra HD with HDR

Dolby Laboratories teamed with Envivio to showcase a live feed of Ultra HD video with High Dynamic Range (HDR) at IBC. The technology pairing used Muse video processing software and Dolby’s Dolby Vision and audio format Dolby AC-4.

At IBC an HEVC feed along with HDR information was encoded by Envivio Muse Live UHD in real-time and played back on a 65” Dolby Vision compatible 4K television. The Envivio encoder has been used in successful Ultra HD broadcast events, such as FIFA’s World Cup, and the French Open tennis tournament for distribution across satellite, cable TV, terrestrial or IP networks.

Envivio claims to be the first to demonstrate real-time encoding in both Dolby Vision and audio format Dolby AC-4.

“With Dolby we have broadcast events such as the French Open in 4K with AC-4 audio, to demonstrate how our technologies together help the video industry move to the next level of quality audio and video delivery," said Julien Signés, CEO, Envivio. “With the added support of HDR, we are highlighting the readiness of the video industry to move to the to the next level of audio and visual experience and delivering images that engage the senses and stir the emotions of viewers anywhere across the globe.”

Said Giles Baker, svp, broadcast business group, Dolby Laboratories, “At IBC Dolby and Envivio will show the industry’s readiness to deliver Dolby Vision and show how it delivers images that captivate the viewer’s senses with astonishing brightness, incomparable contrast, and brilliant colour you can feel,” said. “With a wider colour gamut and HDR, Dolby Vision revolutionises the viewing experience in the cinema and on TV, and Dolby is working closely with key partners like Envivio to bring these experiences to broadcast viewers around the world.”
