Comcast announced its new RealTime4K technology delivered the Super Bowl LX stream with just a 17-second delay, a speed that rivals traditional broadcast. The low-latency feed was nearly 50 seconds faster than competing streaming services, effectively making the viewing experience spoiler-proof for Xfinity subscribers.
Beating the group chat: "Delivering the fastest path from stadium to screen is the ultimate benchmark for live sports,” said Michael Pilquist, Comcast's Vice President of Video Architecture, in the company's announcement. The goal is to give customers "the speed that keeps them ahead of spoilers, texts, and social media.” Subscribers with a compatible X1 set-top box could access the stream on a dedicated Peacock-branded channel.
Under the hood: The performance boost comes from network upgrades that remove compression steps from the delivery pipeline. The process pushes 4K programming at what Sports Video Group reported was double the bitrate of standard 4K and five times that of HD.
The Super Bowl feed isn't a one-off, either. Comcast is using the same technology for its 4K feeds of the Winter Olympics, establishing low-latency as the new standard for its live sports coverage. Meanwhile, a separate third-party report from Stats Perform offered its own latency measurements for the big game. The low-latency push appears to be paying off for Comcast's streaming service, which saw Peacock stream a record 6.3 billion minutes of Olympics content over the first 11 days of the games.
