UEFA Champions League final the first live sports TV broadcast using HDR
Match in 4K UHD with Dolby Atmos on BT Sport on BT TV, and, via YouTube in 4K UHD
BT Sport this weekend conducted a world first by broadcasting, live, the UEFA Champions League Final using High Dynamic Range (HDR) technology in Ultra-High Definition (UHD) with Dolby Atmos® sound at a private screening in London. The match was also available for the first time ever in Virtual Reality to fans. The milestones are part of a series of innovations led by the broadcaster in conjunction with partners across the televisual and technology sectors.
The UEFA Champions League final on BT Sport used the latest broadcast technology, giving viewers the best pictures and the best sound experience available, with the game available for the first time in 4K UHD on YouTube and 4K UHD with Dolby Atmos sound on BT TV.
Additionally. BT Sport deployed a number of innovations and new services with its partners:
- HDR: High Dynamic Range (HDR) increases picture quality by preserving details in the darkest and brightest areas of a picture and allows for more natural, true-to-life colours that are closer to how we see them in real life. BT Sport developed some of the first ever live workflows for the demonstration of the live coverage of the weekend’s final.
- Virtual Reality: BT Sport gave away free Virtual Reality (VR) Google Cardboard headsets to football fans ahead of the game. For the first time ever the UEFA Champions League final was available through a number of 360°streams via YouTube and also in a new BT Sport Virtual Reality App which allowed viewers to choose between a 360° produced programme with commentary and graphics, or select their own camera viewpoint* and all for free.
- Free: BT Sport once again made this season’s UEFA Champions League and UEFA Europa League finals available for free to as many people as possible, on YouTube, the BT website, BT Sport channels and the app, underlining BT’s commitment to make televised sport more accessible to fans.
Jamie Hindhaugh, chief operating officer, BT Sport, said: “This weekend’s broadcast was a big step forward for the industry: from a live production perspective we are now declaring ourselves HDR ready. Our ambition is to deliver the very best pictures and sound and we will be looking at how we can deliver HDR as a core proposition.
“Innovation and collaboration with our technology partners is core to the way BT Sport works. Additionally the support of valued partners such as Dolby, UEFA, the Premier League and more, provide the scope for us to expand technology for the benefit of fans. Our editorial aspiration since we launched is to be at ‘The Heart of Sport’, bringing our audiences closer to the action.”
