In conversation with The edge, CBS confirmed that the Super Bowl will stream in 1080p in 2021 to avoid lag or stability issues. CBS has never streamed an NFL game in 4K HDR, and the broadcaster’s use of remote edits during COVID-19 makes managing a high-bandwidth stream difficult.
Last year marked the first (and only) time the Super Bowl was streamed in 4K HDR. But that stream was broadcast by Fox Sports, which started offering 4K games in 2019. It’s also worth nothing that while the Super Bowl 2020 aired in 4K HDR, the actual game was shot in 1080p HDR and scaled up for broadcast.
CBS says that, despite the lack of 4K and HDR, it plans to keep the Super Bowl LV stream as reliable and lag-free as possible. You can tune in to the CBS channel on February 7th or stream the game in glorious 1080p through CBS Sports and NFL streaming apps.
