Hongsu Jung, CEO of 4DREPLAY, said, “The prolonging of COVID-19 and the resulting consistent hosting of sporting events without on-site spectators is making viewers even more nostalgic for the feeling of watching a game offline in person. The broadcasting company personnel who are responsible for streaming the world’s biggest sporting event have the added responsibility of conveying the atmosphere on-site to fans watching from home so that fans feel like they are physically present.
“4DReplay features each athlete’s performance in a 360-degree view, which allows us to show every movement made by the world’s top athletes — the outcome of years of sweat and tears — in a high degree of detail that we believe will impress viewers. For team events, performances will be shown for different angles per team. Our videos will help viewers to better understand a particular sport through their multi-angle portrayal of athletes’ momentary decisions and performance.”
NBC used 88 cameras on one hole at Torrey Pines for the 2021 US Open. According to Tod Leonard in Golf Digest, “On the sixth hole on the Torrey Pines South Course alone, there were 88 cameras to capture the players’ swings. Let that sink in. Eighty-eight. On one tee box. That’s more cameras in one spot than NBC had on the entire grounds at Torrey Pines in 2008. The cameras, set up in a ring around the tee box, are part of the 4DReplay developed by Cisco that show a player’s swing at 360 degrees, and the video can be paused at 34 different junctures in the motion.”

After recording the swings, the video went to a 4DReplay truck on-site where producers pushed the content to the US Open app, allowing fans to choose and watch the swings of their favorite players on their phones. This footage was also available to NBC lead analyst Paul Azinger, allowing him to examine in unprecedented detail the swings of the world’s best male golfers.
